1 1/5 1.0 PURPOSE This specification describes the minimum requirements for all activities involving hoisting, moving or transporting cargo using equipment such as mobile cranes, hoisting equipment in underground mine shafts, winch-activated subsoil extraction and transportation equipment, vehicle-mounted articulated cranes, cargo elevators, tower cranes, overhead cranes, electric hoists, ore handling equipment, monorails, gantry cranes, cargo handlers and tire handlers. It is also applicable to hoisting accessories. It does not apply to manual cargo handling. For equipment used to hoist, move or transport cargo that is not contained in the above list, a risk analysis must be carried out in order to guide and determine the applicable requirements. 2.0 OVERHEAD Overhead cranes must have the following features: Sound alert for bridge movements; Visual indication of maximum load capacity, visible at a distance; Guardrail or lifeline protection for workers circulating on high parts of the structure; Electromechanical, electromagnetic or electro-hydraulic braking mechanism within the hook movement system; Fault circuit interrupting devices; Limit switch for loose cables; Limit switches to control speed of all movements; Overload sensor; Excess-speed sensor; Individual electronic excess-speed sensors for each hoist drum, and differential speed sensors to monitor the drums, in the case of bridges with two hoist drums and cables activated using differential reduction; Anti-collision sensors for spans with more than one bridge; Safety braking mechanism incorporated into hoisting system, in the case that the overhead crane s power supply is interrupted; Hook with safety lock; Removable shutdown switch for equipment controlled by radio (remote control) and wires; Radio controls with shoulder holsters (or a similar mechanism) to prevent them from falling and being set off accidentally; Standardized visual design of activation controls; Device to lock wheels on rails to prevent derailment. Overhead cranes equipped with an operator s cabin must also have the following features:

2 2/5 Safety mechanism that enables the bridge s movements to be stalled before the operator accesses the cabin; Safe access routes to the bridge, trolleys and operator s cabin. In the case of access to the bridge being on the same level as the bridge s trolley rails, there must be gates that normally remain shut; Operating cabin that meets ergonomic requirements in terms of internal work space, view, temperature, noise and instrument configuration. The cabin must also be equipped with safety instruments to protect 3.0 HOISTS This specification is for general purpose hoists. Any site specific requirements such as environmental (corrosive, wet, dusty, hot, etc. areas), high lifts, ergonomics, etc. must supplement this specification. All hoists will be in accordance with the following applicable standards: ASME B30.16 Safety Standard for Overhead Hoists (Underhung) ASME B30.21 Safety Standard for Manually Lever Operated Hoists ASME HST-1 Performance Standard for Electric Chain Hoists ASME HST-2 Performance Standard for Hand Chain Manually Operated Chain Hoists ASME HST-3 Performance Standard for Manually Lever Operated Chain Hoists ASME HST- Performance Standard for Electric Wire Rope Hoists ASME HST-5 Performance Standard for Air Chain Hoists In addition to the above ASME standards, all hoists will have: WWL (working load limit) load limiter (mechanical) ie overload protection visual indication of maximum load capacity, visible at a distance hook with a spring loaded safety latch Electric hoists must have the following features: Safety braking mechanism incorporated into hoisting system, in case the power supply is interrupted; Removable shutdown switch for remotely controlled equipment; Standardized visual design of activation controls. Electric hoists to have an ASME H duty rating unless noted otherwise Electric hoists to have NEMA control housing unless noted otherwise Electric hoists to be CSA certified

3 3/5.0 GANTRY Gantry cranes must have the following features: Sound alert for gantry crane in movement; Visual indication of maximum load capacity, visible at a distance; Electromechanical, electromagnetic or electro-hydraulic braking mechanism within the hookmovement system; Fault circuit interrupting devices; Limit switch for loose cables; Overload sensor; Excess-speed sensor; Safety braking mechanism incorporated into hoisting system, in case the gantry crane s power supply is interrupted; Hook with safety lock; Removable shutdown switch for equipment controlled by radio (remote control) and wires; Radio controls with shoulder holsters; Standardized visual design of activation controls; Signs/markings on ground to indicate gantry crane movement safety area. 5.0 MONORAILS Monorails must have the following features: Visual indication of maximum load capacity, visible at a distance Structures properly grounded 6.0 REMOTE RADIO CONTROL SYSTEMS (RF COMMUNICATIONS) All Radio Remote systems (including licensing) shall meet the requirements of the Vale Limited, Division Radio System Guidelines (most recent revision). This document can be obtained by contacting the Vale RF Communications Department. Note: the standard remote style at Vale is Cattron. In addition, all cranes are to come with a pendant controller, in the event that the remote controls become inoperable.

4 /5 7.0 DRAWINGS Drawings, at a minimum, are to follow the requirements of Vale Standards SPEC and SPEC REFERENCE DOCUMENTATION The following documents are related to this specification and shall be used to their latest revision: Vale Limited Division Radio System Guidelines CSA B167 Overhead travelling cranes Design, inspection, testing, maintenance, and safe operation.

5 5/5 8.0 REVISION AND TRANSITION NOTES Revision notes describe: what was changed, and if applicable, why it was changed, and the plan to implement the change, including whether changes are retroactive. Note: The revision notes are a summary of the changes and may not necessarily be a complete list. A risk code is entered for each revision and if applicable, the revision notes will describe how risk was addressed for the revision. Risk Code A Risk Category This revision is a minor change and/or introduces no risk. B C Risk has been addressed for this revision by the reviewer and approver. Low risk or no new hazards identified. For this revision, a PHR or other risk management tool has been used to address risk and minimize hazards. This risk assessment has been documented and is available through Central Engineering. Rev Revision Notes New document issued according to Vale RAC requirements (Requirements for Critical Activities). Load limited requirements added in Hoist section. This revision is applicable to all new hoists installed after this date. (June 17, 2013) Format updated Requirements for Radio Remote Systems (RF Communications) added Risk Code Approved by Reviewed by Issue Date YYYY/MM/DD --- BM BM 2012/0/ MDF MDF 2013/06/17 A M.Fogarty B.Lavers 2016/09/ Review No changes A A.Alaeddine M.Fogarty
