4 Page 3 of 23 Part B 1 Purpose To specify to managers and users, factors that must be considered for controlling, safely using and operating rail mounted cranes in the railway environment. 2 Scope This standard applies to all personnel involved in the operation of all types of rail mounted cranes. 3 Key definitions Competent Examiner A person who possesses sufficient knowledge in crane working to be able to assess the competency of the persons being examined in their duties and holds an authoritative certificate in a recognised training and instruction method. Controller A trained and certificated person capable of:- devising a safe system of work for a crane operation, specifying cranes and lifting tackle, identifying numbers of staff required for the lifting operation, communicating the safe system of work to staff, controlling the operation of cranes and supervising personnel in connection with the lifting operation. Crane For the purposes of this standard reference to crane will mean a rail mounted, power operated lifting machine capable of lifting, lowering or suspending loads at various radii and specifically designed for use with railway operations, breakdown work or infrastructure maintenance/renewal. All references to rail cranes throughout this standard will apply equally to Road-Rail cranes when operating in the rail mode. Emergency An event requiring immediate action to avoid danger to life, health or serious interruption of essential public services. Operator

5 Page 4 of 23 A trained and certificated person capable of:- operating the crane within a defined safe system of work, knowing the limits of the crane's operation, reporting defects, carrying out daily servicing and inspection, operating the crane's safety equipment in the event of an emergency. Operator for Maintenance Purposes A trained and certificated person capable of functionally testing the crane. Slinger A trained and certificated person capable of:- carrying out slinging duties, directing the movement of loads by crane power within the safe system of work. Slipper A device which, when fitted on the rail head, will safely stop a slow moving rail vehicle when the wheels of the vehicle run on to it. 4 Crane Acquisition 4.1 Before a crane is used technical approval must be sought from the infrastructure owner or their appointed agents. In the case of repetitive requests a type approval may be applied for. The infrastructure owner will take into consideration the appropriate Group Technical Standards (Nos. GM/TT0109 Engineering Acceptance of Rail Vehicles for Operation on Railtrack, GC/TT0257 Engineering Design of On-Track Plant and GC/TP0382 Engineering Acceptance of Road-Rail Plant) to determine whether or not the crane will be safe and satisfactory for the required duties and operating conditions. 4.2 In addition the following features will be required:- having a safe working load of more than one tonne must have an operational safe load indicator (S..I.), with provisions to take account of canted track or in the case of hydraulic loaders a load limiting device. must have operational power brakes independent of the traction drive mechanism. NOTE: The above conditions will not apply retrospectively for equipment used on the railway at the date of issue of this standard.

6 Page 5 of 23 must have a legible duty table showing values of load and radius prominently displayed in the cab (for operator use) and externally on each side (for controllers use). Excavators used as cranes are exempt from having a table on the outside of the machine. Diagrams showing the gradient working restrictions and jib height in relation to rail charts must be displayed in the operating cabs. 5 Registration 6 Maintenance All cranes must be registered so that they are uniquely identified for operational and maintenance purposes. 6.1 All cranes shall be subject to maintenance and such maintenance shall be recorded. An indication of when the next maintenance and statutory examinations are due shall be apparent or available to the user. 6.2 The maintenance and operator servicing schedules must be approved by the infrastructure owner to ensure that they at least meet the minimum safety requirements for use in the railway environment. 6.3 A log book must be provided for each crane, to record daily checks, maintenance, defects and repairs. 6.4 Servicing, maintenance or operational checks on cranes in the vicinity of live overhead wires or ground conductor systems is only permitted in accordance with the safe system of work defined in GC/OG0020 Operation of Plant in the Vicinity of Overhead Electric Supply ines.

7 Page 6 of Persons must not walk, or work, under raised booms or attachments, whilst maintenance or repair is being undertaken, unless the equipment has been secured by external means. 6.6 When a crane is hired and the hire company undertakes to perform maintenance, it is the hirers (users agent) responsibility to ensure that a satisfactory maintenance programme exists and that the crane is made available for it to be implemented. 6.7 The operator must ensure before use, that the crane and its associated equipment are in good order and that laid down daily inspection and servicing have been carried out. 6.8 The crane must be withdrawn from service for any defect which is considered likely to affect its safe operation and a notice stating "DANGER - NOT TO BE USED" placed over the controls. The controls shall be immobilised and the maintainer informed. Any defective component must be retained for technical investigation by the maintainer / technical department. If such a defect occurs during work this must be reported to the controller. 6.9 Fuelling. Fuelling must only be undertaken in accordance with local instructions. Fuelling must not be carried out in confined spaces. Smoking is strictly prohibited during any fuelling operations. 7 Modifications 7.1 Modification to type approved cranes that affect the safety of the railway operation must be approved by the infrastructure owner or their appointed agents. 7.2 Where significant modifications are made to the crane a reassessment of the training needs must be made.

8 Page 7 of 23 8 Statutory Requirements 8.1 Periodic statutory examinations shall be in accordance with the requirements of the Factories Acts, Where the crane is required to work on a site where the Construction Regulations are in operation (i.e. when constructing a new railway) then the Construction (ifting Operations) Regulations 1961 apply. 8.2 The records of all cranes shall be kept in a location agreed between the user and the owner. 8.3 The controller must ensure the crane is not overdue for statutory examination. 8.4 In the event of an accident or dangerous occurrence, the requirements of the Reporting of Injuries, Diseases and Dangerous Occurrences Regulations 1985 (RIDDOR) and The Railways (Notice of Accidents) Order 1986, must be complied with. 9 Training and Authorisation 9.1. General The use of a crane requires staff to be trained, authorised and certificated. The following categories will apply; Controller, Operator, Slinger or Operator for maintenance purposes only. 9.2 Selection of Personnel Persons selected for training on cranes shall have the following attributes: be a minimum age of 18 years at the time of the examination be fit, with regard to eyesight, hearing and reflexes (As defined in the GO/ZT0005 : Medical Fitness of Persons Competent in Personal Track Safety) able to judge distances, heights and clearances physically capable of carrying out the required duties.

9 Page 8 of Training The training syllabus shall contain sufficient content as appropriate to enable staff to work safely and competently with the crane. This will include such facets as:- knowledge of this standard (GC/0G0004) the relevant parts of BR Rule Book (BR87109) significance and working of the S..I. protection of vehicles on running lines principles of lifting, slewing, craneage of loads safety of passengers and staff on platforms or on the line full appreciation of principles and modes of operation of the crane as applicable determining the weight of the load and the load/radius relationship use of the cranes emergency equipment and procedures fire and other emergency procedures function of all operators controls use and purpose of warning devices hand Signals as defined in BS safe control of the plant while performing its full range of duties working on gradients multiple crane lifting reporting of defects safety precautions to be taken when working in the vicinity of overhead power lines ( GC/OG0020 Operation of Plant in the Vicinity of Overhead Electric Supply ines) the correct use of a two way radio to control lifting operations. The emphasis on the items will depend upon the skills being taught i.e. controller, operator, slinger, or operator for maintenance purposes only. The training should be both practical and theoretical in content and must entail off the job classroom activity Whilst training, candidates shall be under the direction, at all times, of a person trained and authorised for that class of work.

10 Page 9 of Authorisation On completion of training, staff will be examined, by competent examiners, in one of the following defined skills:- Controller Slinger Operator Operator for Maintenance Duties only If the trainee is deemed competent by the examiner, the trainees manager may give full authorisation and issue an authorising certificate containing the following information :- person's full name employer's name and address class of certificate (i.e. controller, operator, slinger or operator for maintenance duties only) type and or make of crane authorised to operate (operators only) date of issue and date of expiry any limitations of validity (e.g. may only be valid in certain areas) examiner's name, company address and signature authorising manager's name, address and signature An operator's certificate shall be issued for a specific make and type of crane to which the authorisation relates. Where additional types of crane are required, the individual shall be trained and examined in accordance with the requirements specified and an additional certificate issued accordingly The training assessment and authorisation must be recorded for audit purposes The certificate shall be valid for 2 years, after which the person concerned shall be re-examined Where the member of staff fails to demonstrate the required knowledge of procedures, the certificate shall be withdrawn immediately and if considered suitable they shall be re-trained and re-examined.

11 Page 10 of Where a member of staff has not carried out their certificated duties during the previous 12 months, the certificate shall be withdrawn and the individual shall be re-familiarised and re-examined When a crane is hired with an operator, that operator shall be in possession of a valid authorising certificate (issued under the conditions specified in this section) for the particular type of crane concerned. 10 Safe System of Work A safe system of work for the operation must be established by the Controller Duties of a Controller (Planning) The controller must obtain all the necessary information to ensure a safe lifting operation and decide on a work plan. FOR A SCHEDUED WORK, THE WORK PAN MUST BE DOCUMENTED. Exceptionally the work plan need not be documented for rigid arm loading devices as specified in The work plan must take into account the following:- the weights and symmetry of the load(s) to be lifted, taking into account any possible adhesion between the load and structure. When a load cannot be weighed, calculated, or estimated accurately, assistance must be obtained from a relevant technical department the weight of the lifting tackle to be used, for which due allowance shall be made in the crane loading the radius, track cant and track gradient on which the crane will be required to lift each load the details of any special instructions which may apply to the lifting equipment to be used, or to the method of lifting to be employed the suitability of physical ground conditions to withstand the concentrated loads imposed by wheels or outriggers of the crane the clearance between the crane and loads to overhead and adjacent structures e.g. bridges,

12 Page 11 of 23 telephone cables, etc. Where applicable this must be indicated on a site diagram any sub-surface works or services e.g. culverts, drains, building construction, etc., which might affect the safe operation of the crane all other rail vehicles. These must be listed, their use defined and their position and direction of approach clearly indicated an assessment for the possession requirements of running lines upon which the crane stands and adjacent running lines (including electrical isolation Ref. GC/OG0020 ( Operation of Plant in the Vicinity of Overhead Electric Supply ines) any requirements for liaising with other parties responsible for work in the same possession the requirement for slewing overhead line equipment for the duration of the work the provision for controlling the operation on site any requirements for cranes working independently but in close proximity on the same site. The limits of travel must be agreed in advance any requirements for multiple crane lifting. All factors and constraints must be accurately assessed as far as possible and the cranes down rated as appropriate for the task. Where all the factors have been identified and the lift is being monitored on instruments, the cranes may be used up to their safe working load. Further guidance can be obtained from the standard SP-PM-3 (Staff Involved in the Planning, Supervision and Operation of Simultaneous ifting of a oad with Two ) the requirement to work on a bridge, arch or viaduct. Advice and authority of the relevant Civil Engineers Department must be obtained to ensure the structure is capable of supporting the crane and the assessed loads the limits of the lifting operation, the marking of the boundary of the hard hat area and positions of safety for work groups.

13 Page 12 of After the controller has produced the work plan and where the work is of a repetitive and simple nature, the controller may delegate the control of the operation to a slinger provided that:- the crane is not required to work where it or the load may foul a line on which trains are required to run the controller maintains overall control of crane work within the operational site All staff involved must be fully briefed and understand their part in the work plan Duties of the Controller (On-site) - General Requirements The operation must be under the direction of a controller on site. This person may be different from the controller who developed the work plan. On jobs of a long duration, more than one controller may be necessary to complete the operation. Exceptionally where the crane involved is a rigid arm loading device and where the overturning moment is limited by means of a hydraulic relief valve or similar, such that the device cannot be overturned, then it is adequate for the operator to assume the roles of controller and slinger The person directly controlling the operation on site must remain within the immediate vicinity of the crane operation All staff must be briefed and be aware of the intended crane movements, as indicated in the work plan In accordance with GC/OG0021 Control, Safe Use and Operation of oose ifting Tackle, each item of loose lifting tackle to be used must be checked to ensure that it is suitable for the lift, in a serviceable condition and used in the correct way The controller must ensure that:- adjacent lines are not fouled by any part of the crane, equipment or its load, unless suitable protection has been taken in accordance with the British Railways Board Rule Book (BR 87109)

14 Page 13 of 23 before lifting commences steps are taken to see that the load is free and neither pinned down, nor jammed in any way when lifting or lowering loads through hatchways, they will not foul hatch coamings, the sides/tops of openings, or rigging if a load is found to be out of balance it is lowered and suitably balanced before resuming the lifting operation the load is not lifted higher than is necessary to clear obstructions persons do not stand below or touch a suspended load. Where there is a need to guide a load, or prevent it swinging, this must be achieved by the most appropriate and safe means, involving if necessary the attachment of ropes and assistance of other slingers or staff when chains or slings are being removed, care is taken to prevent catching the load loads are not allowed to remain suspended longer than absolutely necessary for the operation the cab or crane controls are not vacated whilst the crane is working cranes are not overloaded or the safe working load indicated exceeded. If any inadvertent overloading occurs, this must be reported to the maintainer if an S..I. defect occurs on any crane whilst in service, the crane is only permitted to remain in use to complete its immediate lift. Work can continue, provided that, it is only used in conjunction with an emergency safe load indicator kit and cranes fitted for over end duties are returned to full slew duty conditions. The defect must be entered in the log book and on completion of the task, the crane must be removed from service until the defect is rectified. Note: If an S..I. defect occurs on a recovery crane, either being used or proposed to be used, and an emergency SI kit is unavailable, the crane may only be operated in an emergency situation (see definition). The controller must take exceptional care in establishing the weight of the load (including the tackle) and the radius. This shall be done by taking the weight marked on the load (or by calculation making due allowance for unknown factors) and by measuring the radius.

15 Page 14 of The controller must check for the most restrictive track cant on site and ensure that the work is carried out within the duty dictated by that cant The controller must consider the use of outriggers, where provided, in the following situations:- when the load is approaching the "free on rails" duty limits when making short radius lifts over the high rail on canted track The controller must ensure rail clips are not used on rails without the permission of the Civil Engineers Department. Rail clips must only be used in conjunction with outriggers, but in no circumstances shall they be used to increase the capacity of the crane The controller must ensure that match wagons or relieving bogies have been detached and properly parked at a safe distance as laid down in the plan The controller must ensure that when the crane is slewing towards the high side of a canted track, great care is taken to ensure that the load does not foul the crane, or that the jib is not brought inside the minimum working radius with the resulting danger of the crane falling backwards Care must be taken when lifting loads on the high side of canted track. Outriggers must be repacked firmly after the first lift, and before slewing on to the low side When a crane without power brakes is working, a competent member of the ground staff must be appointed by the controller as a brakesman. The brakesman shall give general assistance to the crane operator Where it is found that the travel brakes are non operational, the crane may be worked coupled to a locomotive providing the crane is through braked or the operator has an adequate hand brake that he could operate in an emergency and the operation authorised by the controller The controller must ensure that cranes which cannot be moved under their own power are only moved when coupled to a locomotive.

16 Page 15 of If a locomotive is attached to a crane, the locomotive driver shall be briefed in the plan, made aware of signals to be used in the operation, verbally instructed to commence operation and work to the signals given The controller must ensure that clearance is allowed between any part of the load, crane and adjacent vehicle or obstruction, to ensure the safety of public or staff. If the clearance is less than 600 mm (24 ins) then the area must be designated a no go area for personnel Duties of a Controller On-site - Gradient Working The controller must ensure that : when a crane is being coupled or uncoupled, the parking brake/s are applied, and the travel gear, where fitted, disengaged. On gradients steeper than 1 in 260, additional protection must be provided by a rail slipper under the crane wheels a crane must not be coupled or uncoupled when standing on a gradient steeper than 1 in 70 when working on a gradient that changes over the limits of work, the steepest gradient shall be taken as the ruling gradient for the purpose of determining gradient protection if there is a notice in the cab indicating the gradient working capabilities and the travel gear and brakes are fully operational then the crane may be worked to the conditions stated in that notice. Where there is no notice or the travel gear or brakes are not operational then it must be worked in accordance with the limitations specified in Diagrams 1 or 2 pages 16 & 17 where the limits of work involve moving over a summit then gradient protection shall be provided to suit the ruling gradient on each side of the summit in accordance with the diagrams 1 & 2 pages 16 & 17

17 Page 16 of 23 where the track on which the crane is working is broken, or is otherwise unfit to take the crane, a baulk of timber shall be secured across the rails as in diagrams 1 & 2 pages 16 & Where the point of break in the track is continually moving, rail slippers may, at the discretion of the controller, be substituted for the baulk of timber. Rail slippers may be used in any other circumstances where the controller considers that the baulk of timber is insufficient to protect the crane.

Similarly, if because of weather conditions or other causes the rails are wet or greasy the pair of slippers must be kept as close to the crane as practicable for the operation, and a partial application of the crane hand brake should be made Duties of Controller (On-Site) - Preparation For Crane Transit. The specific instructions under this heading must be read in conjunction with BR 30054/6 "Preparation and Working of Freight Trains, clause D7, Instructions relating to Power Driven rail " When moving a crane from location to location, the controller must ensure the crane is prepared for travel in train formation and must see that, where applicable:- the crane, match wagon and relieving bogies, are properly coupled together. Relieving bogies must be properly adjusted

19 Page 18 of 23 the jib is correctly stowed with its rubbing plate properly resting on the cradle of the match wagon, the hoist and derrick ropes slack and the hook assembly correctly secured. Special attention must be given to cranes with articulated jibs to ensure the fastenings for securing the jib during working are released the tail locks/slew pin on the superstructure and any security chains are secured to prevent excessive movement of the jib and balance weights the outriggers are fully retracted, secured and rail clips are correctly stowed all spring stops are free, bearing screws or packing are fully released, so that the springs may take the load the travelling gear is disengaged. This shall be proved by attempting to move the crane under its own power in both directions. When proved, the gears should be locked in the "OUT" position the slewing brake is released or applied as appropriate to the crane type the parking brakes are on, unless the crane forms part of a train and is coupled up all pressure has been released from the air receivers all other equipment belonging to the crane is properly stowed away ready for travelling Duties of the Slinger The slinger shall be responsible for attaching and detaching the load to the crane and for using the correct lifting gear and equipment in accordance with the work plan For repetitive work and where delegated by the controller the slinger shall be responsible for initiating and directing the safe movement of the crane in accordance with the work plan. If there is more than one slinger, only one of them should have this responsibility at any one time.

20 Page 19 of Duties of the Operator The crane operator must prepare the crane in accordance with the specific procedure for that crane, and ensure that:- the parking brake is applied on the crane and associated match wagons when a crane is fitted with air or vacuum brakes, and is to work coupled to a locomotive, the brake pipes are correctly coupled between the crane and the locomotive the tail/slew locks and any hook retaining chains have been removed in a manner that will prevent free movement of the jib the springs have been relieved by adjusting the bearing screws or other forms of spring packing and where applicable, adjustable counterbalance weights are moved into the working position the jib is raised correctly. In the case of an articulated jib, care must be taken to ensure that this is in line with the superstructure and the jib foot is correctly located and secured Before commencing work the operator must carry out a full functional test without load and must ensure that all motions and safety devices are functioning correctly Operators must ensure that they have been briefed on the work plan and understand from whom they will receive their instructions Before commencing work the operator shall, by reference to the duty table, assess the lifting duty within which the crane will work and select the appropriate setting for the S..I. or other warning device where fitted. At no time during the lifting operation will the S..I. or other safety devices be overridden or disregarded The crane operator must be vigilant at all times especially when working on canted track or where the track is in poor condition. The capacity of a crane is reduced in these conditions. When slewing on canted track or when travelling with the jib over the side on track where the cant changes, the true radius to the hook will change Where a crane is equipped with two hooks on a single jib (main and auxiliary) only one hook must be

21 Page 20 of 23 used for the lifting operation. The operator shall ensure the hook not in use is free of load, lifting tackle and is elevated to its maximum height oads must only be lifted vertically and must never be dragged. Operators must not rely on safety devices cutting out and must be able to stop the movement before the limits of the crane are reached Before commencing or changing the direction of movement of a load, the operator must ensure it is safe to do so and give ample warning of his intention If a load becomes jammed during a lifting operation, the operator must cease operations and inform the Controller immediately When travelling with a suspended load the operator must, where possible, ensure the load is carried as low as possible and the load is not allowed to swing excessively The operator must follow the work plan and any proposed changes or deviations to the plan must be authorised by the Controller on site The operator must not allow any person to travel upon a crane or any attachment except:- where there is designed provision for the carrying of personnel or for the purpose of instruction, or technical investigation and where sufficient safety precautions are being taken The operator, when operating a power braked crane working in conjunction with a locomotive, must ensure that a brake continuity test has been carried out. The crane brake application valve must only be used in an emergency The operator must not leave the crane unattended, even for short periods, unless:- the load has been removed from the hook or bales and the jibs have been brought in line with the track the hook or bales has/have been raised to a safe position clear of other operations the engine has been stopped and the controls left in neutral position

22 Page 21 of 23 the brake and superstructure locks have been applied and the wheels scotched. NOTE:- For short periods it is unnecessary for the jib to be placed on the match wagon When it is necessary for the crane operator to park the crane for longer periods, in addition to the requirements in , the following shall also be carried out - The crane shall be parked on a line or siding not required for traffic during the period of parking. The points leading to this line shall be clipped and padlocked in order that the siding shall be protected. If it is not practicable to lock the points, a baulk of timber must be secured to the rails, as specified in diagrams 1 & 2 on pages 16 & 17, 18 metres (20 yds) from the crane, with a red flag or red lamp adjacent. the jib is lowered outriggers/tail/slew locks or chains, where provided, must be properly secured and the crane cab doors and tool boxes locked all air pressure shall be released from the receivers The operator must not permit the crane to be used for the movement of other plant or rolling stock, unless specifically designed or modified for that purpose General Safety Fire Prevention: The machine must be kept clean and free from excess oil, grease etc. Smoking is prohibited in any cab. Oil or similar flammable material must not be carried on the machine unless it is held in purpose built containers and then only in positions provided for in the design of the machine.

23 Page 22 of 23 Under no circumstances may.p.g appliances be used on a machine unless it is in an approved permanent installation..p.g. bottles must not be carried on a machine unless they are part of the fixed installation or carried as part of an authorised load adders must not be:- carried on machines unless specifically permitted by the safe system of work used adjacent to an open line. Where use of ladders is permitted they must be:- of wooden construction or other non conducting material and must not have any metal reinforcement running along the sides kept at a point designated by the person responsible for safety when not in use If an electric shock is experienced as a result of a machine defect then the crane should be stopped, the maintainer called and an entry made in the log book. 11 Personal Protective Equipment 11.1 All staff must wear safety helmets when lifting is taking place Staff must wear protective clothing and equipment where required. Where the crane displays a noise protection warning sign, then staff within the limits defined on the sign must wear approved ear defenders. The minimum requirements for personal protective equipment are: Safety helmet to BS 5240 (in date) Safety footwear High visibility clothing Ear defenders if applicable eather faced gloves for slingers
