11 BEARING CAPACITY The Bearing Capacities tabulated below are based on the Hiley Formula; Bearing Capacity (tonnes) = Blow Efficiency x E/(s+2.54), where E=Hammer Energy (kg.m), s=final Set per Blow (mm/blow). Blow efficency for a hydraulic hammer is typically around 80% and adding a safety factor of 2 permits the formula to be modified to Bearing Capacity (tonnes) = 0.4 x E/(s+2.54). Irrespective of hammer selection the Hiley formula is a simplified analysis and actual bearing capacity achieved will be significantly affected by pile type, length, mass and stiffness, in addition to prevailing ground conditions.the Hiley formula was originally devised to estimate pile bearing capacity based on actual site measurements. The Dawson Hydraulic Impact Hammer has a visible stroke marker on the side of the hammer. This marker can be calibrated to indicate maximum and minimum hammer energy outputs and any energy figure between those two limits. In addition, it is possible to relate the hammer blow rate at final drive to hammer energy output as set out in the table and on the graph shown below providing hammer performance meets with manufacturers specifications. Please note that practical refusal is considered to be 10 blows/25mm. Driving in excess of 10 blows/25mm for more than 150mm of pile penetration or any driving in excess of 20 blows/25mm will invalidate the hammer warranty. 11

16 HYDRAULIC HAMMER POWER PACKS IMAGE OF DHP170 This Dawson power pack is fully self contained, including all oil and fuel reservoirs, prime mover and hydraulic circuitry. The power pack is designed to be directly connected to the working element of the system; however it can be connected through further hydraulic valves to perform alternative operations with guidance from the manufacturer. The power pack is designed to produce a fixed oil flow rate at a preset pressure to supply hydraulic piling hammers in various enviroments from hot summers in Kuwait to cold winters in Ontario. The diesel engine runs at a fixed RPM and is calibrated against the pump flow rate. A built in offline filtration system is used to condition the hydraulic oil to 2 microns and remove an amount of water contamination.

18 ADDITIONAL EQUIPMENT A full range of accessories are available from Dawson to help solve numerous pile driving challenges. If it is not contained within this brochure please do not hesitate to contact us to discuss your requirements there is a good chance we may have met the challenge successfully before. Hydraulic Interface Control Module Integrates the HPH Hydraulic Hammer range wih a vast array of hydraulic power sources e.g. crawler crane, power packs etc, with minimum installation effort. Maximum flow input 400 l/min (107 gpmus) Maximum pressure input 350 bar (5,075 psi) Unit requires a 24V/5A power supply. Dimensions 650x450x470 (LxHxW) Weight 126kg Underwater Kit All Dawson hammers can be set up to operate under water in depths of excess of 100m.

19 e l e c t r i c a l s w i t c h i n g Dawson Construction Plant has developed an industry leading, robust and simple, electronic control system that constantly monitors the drop weight position. This constant monitoring allows the switching timing on the main hydraulic spool to be trended to continually optimise hammer performance throughout varying piling conditions, such as: 1 Hard driving with pile recoiling 2 Soft driving with a running pile 3 Cold hydraulic oil on start up 4 Raking piles DATA CAN BE RECORDED TO A LAPTOP INTERFACE SCREEN MOUNTED ON POWER PACK MAIN PAGE With constant drop weight position monitoring, the velocity of the drop weight is also known, therefore energy output can be accurately measured and is displayed to the operator on the powerpack interface screen. This information can be recorded direct to a laptop via a Dawson software interface, and can be saved in standard spreadsheet formats, giving a blow by blow account of every pile driven and a day to day productivity record. HISTORY PAGE TYPICAL SCREEN SHOTS The main screen displays bar graphs showing hammer stroke & hydraulic oil temperature. An Off Pile indicator confirms when the hammer is securely seated on the pile, and allows piling to commence. There are numerical read outs showing blows per minute, energy per blow and total blows. The lower reading shows blows in LAP cycle. (Measuring blows per increment). The units can be changed from imperial to metric. The history screen provides information on the total number of start ups / total hours / total blows and total energy through out the life of the hammer. 19

21 EXCAVATOR MOUNTED OR CRANE SUSPENDED VIBRATORS Dawson excavator mounted vibrators have been designed specifically to work in place of an excavator bucket to drive and extract piles. The pile can be lifted to vertical using the builtin lifting chain where it is then gripped tightly in a powerful hydraulic jaw. Once secured, the pile is then vibrated with high frequency vibrations so as to fluidise the soil resisting the pile. Downcrowd force applied by the excavator boom, coupled with the selfweight of the pile and the vibrator, provides sufficient force to push the pile into the ground. Naturally, the process works in reverse for pile extraction. The equipment offers a highly productive and cost effective piling rig based around a standard, readily available excavator! Principal Advantages. Compact, robust and reliable no electrics!. Simple and fast attachment to excavator. Minimal height to maximise pile length. Slim design to drive single sheet piles. High power to weight ratio. Universal joint suspension for easy alignment of piles. Extremely low vibration transmitted to the excavator. Enviromentally friendly low noise/localised directional vibration. Automatic hydraulic clamp operation. Flexiblity in application. Flow regulator prevents excessive oil supply to vibrator. Heavy saddles available for crane suspended models Driving / extracting when the movement is less than 1 (25mm) per minute is considered pratical refusal. Driving / extracting when movement is less than 1 (25mm) for more than 5 minutes of driving / extracting or driving at all when penetration is less than 1 (25mm) per minute and amplitude is greater than 1 (25mm) [ vibrator and pile are bouncing] is considered improper use and will void the warranty. Contact DCP for an alternative larger vibrator. 21

As a guide the EMVs typically suit the following base machine sizes: EMV70 (requires 30l/min, 240 bar) ~ 5.517t excavator EMV300 (requires 130l/min, 280 bar) ~ 1235t excavator EMV450 (requires 195l/min, 270 bar) ~ 2545t excavator EMV550 (requires 256l/min, 280 bar) ~ 3055t excavator EMV SELECTION GUIDE There are many variables that determine how effectively a vibratory pile driver will perform. This graph below is a guide, not a guarantee! Vibratory drivers work at their best in granular (gravels and sands) materials, where the amplitude in the pile can fluidise the ground and allow the pile to advance as the ground rearranges itself. They will still function in cohesive materials (clays), but piles will not penetrate as far.

29 EXCAVATOR MOUNTED DRILL Dawson s excavator mounted drilling machine has been designed to fit via an adaptor plate to the stick arm of an excavator and runs via the flow and return lines that normally supply the bucket. There are five models to choose from starting at 17,5 knm up to 48,5 knm that cover a wide range of applications from drilling precise holes in many varied ground conditions, subject to the auger/drill bit, through to stirring the ground prior to using a Dawson EMV vibro piling machine. By selecting the correct drill bit combined with the downcrowd force of the excavator the EMD will make light work of the most demanding conditions. Another benefit of the EMD is that because its mounted on your excavator you can drill vertical holes, anywhere the excavator goes. It s ideal for drilling over casings, on railway embankments, under bridges, or near power lines, + anywhere with low headroom constraints. Key Features. 5 models to choose from 17,5 to 48,5 knm torque. Easy to fit to a wide choice of Excavators. Drill over obstructions, under low bridges, on inclines that traditional rigs cannot do. High Power to weight ratio. Compact, robust, reliable. Connects in place of bucket, using the flow and return lines. Standard hexagonal drive shaft 80mm 100mm 29

35 AUGER CLEANER Spoil from continuous flight augers should be removed at the lowest possible level so as to prevent rig instability and avoid injury to personnel or damage to machinery due to falling debris. Units are custom built to suit customer s drilling rigs and auger specifications. An auger cleaner can be adapted to a variety of different auger diameters and pitches using alternative shells. The shell, or barrel, is attached to the underside of the auger cleaner drive. Auger cleaners provide a fast, powerful and productive means of cleaning all soil types from a continuous flight auger. This becomes increasingly important as the diameters increase, particularly with heavy soils. Models are available to clean auger diameters from 300 to 2,000mm, depending on rig specification.

39 Leader Articulation The leader should have the ability to articulate or pivot (in plan view). This is typical of any rig that has been engineered to undertake sheetpile work though alternative arrangements can be supplied. This feature offers two significant operational benefits:. The entire piling process is faster, more economic and safer when the operator has the ability to see what he is doing. Lead articulation means the operator can position the leader for good visibility with minimum track movement.. The 2Cylinder PushPull unit can accomodate numerous pile profiles simply by articulating the lead and/or adjusting the rotational setting of the individual cylinder assemblies. The example below shows the same 2Cylinder PushPull unit working with Arcelor AZ18 and PU32 steel sheet piles. The centres of the two Modular Hydraulic Cylinder Sub Assemblies remains the same, but the Adjustable Guidance System is altered to correctly align the Clamp Assemblies with the clamping faces of each pile.

49 EURO GROUND RELEASE SHACKLES This robust pile lifting shackle was contractor designed and developed over many years of site use and abuse. The use of these shackles compliments the Feet on the Ground approach to piling. When used in conjunction with the Sheet Pile Threader, there is no need for site operatives to go above the safety of top frame level for interlocking sheet piles or releasing the lifting shackles. The shackles are suitable for lifting all steel piles up to 28mm thick and within the safe working load of the shackle. The shackle is stiffened to resist spreading of the forks when lifting at 90 to the axis of the pile. (See Safety Check List ). When lifting sheet piles in pairs or individual piles weighing more than the Safe Working Load of the shackle, it is necessary to use multiple shackles in order to keep within the safe working load. Pairs of shackles can be supplied mounted on a two legged steel wire rope sling. The advantage being that the standard pair of shackles with lifting sling can be fitted to any pair of Larssen U piles, Frodingham Z piles, pipe or box piles. No additional parts or change of components is necessary. The ring at the top of the sling can be hooked directly onto a standard crane hook block, D shackle or fork anchor. Shackles can also be fitted onto a solid steel cross head according to customers requirements. FEATURES. Robust High Strength cast steel body. High alloy steel plunger. Plunger mechanism concealed for maximum protection. Plunger mechanism easily detachable for maintenance.

67 UNIVERSAL SHEET PILE THREADER The Dawson Universal Sheet Pile Threader has been developed to enable a safe, easy and productive method of pitching sheet piles. The need for a top man is eliminated as all operations can be performed at ground or top frame level. The Universal Sheet Pile Threader can be set up for virtually all Larssen and Z section sheet piles, and once set correctly will quickly interlock the piles with one simple movement. Care should be taken during the setup procedure to ensure that each adjustment is accurately set, extra time spent here will be saved tenfold during operation. Within one pile section there may be several variations. On a Z section interlocks are usually different at each end. The leading can also be left or right hand. The Universal Sheet Pile Threader can accommodate these variations with the simple adjustment of roller positions. This can be accomplished on site by offering the Sheet Pile Threader up to a pile and adjusting the rollers to the correct position. They are now set for a left or right hand threading.

Improve productivity and working safety. The one basic guide frame is standard for ALL Z section piles, ALL straight web piles and U piles of size 2 and upwards. Below this size may require modifications to the main frame, but the principal of operation remains the same. The different sections are accommodated simply by inserting appropriate rollers onto the lower spindles which form part of the lower clamp. These rollers fit the pile profile to give positive and accurate location. Different stop plates are attached to the top grip to suit different pile sections.

73 PILE POINTS & SPLICERS A range of products are available that enhance the performance and productivity of driven piling. Pile Points help to protect the leading edge of the driven pile thus maintaining its chosen mechanical properties. These are available to suit: pipe piles; sheet piles; timber and Hpiles. Piles Splicers speedup the alignment and buttwelding of piles being joined end to end. They are available for pipe as either drive on or weld on items, and for H piles as weld on only. Key Features. Reinforce the pile toe, increasing the piles resistance to buckling, maintaining the profiles shape. Reduce skin friction in certain ground conditions minimising installation forces. Improve the end bearing for load bearing piles. Castin cutting teeth help to break debris and boulders then cut into rock for full bearing, even on inclined strata. May permit the use of lighter piling sections in some applications e.g. pipe piles. Can help to reduce surface damage to coated piles during installation. Points available to suit: pipe, sheet, timber and Hpiles 73
