  • Page 6: Basic Safety Points

    2.1 Basic Safety Points • The vibrator should only be operated by suitably qualified personnel. • There should be visual contact between operator and slinger (spotter) at all times. • Monitor the piling operation constantly – interrupt the process immediately if any danger occurs.

  • Page 7: The Danger Area

    2.1.4 The Danger Area This is an area defined as that being within a 15m(50’) radius of the vibrator. Personnel are at risk when within this area from: • Falling piles – should the pile be handled incorrectly • Liquids under high pressure and associated components •...
  • Page 8 3.0 HOW DOES THE EXCAVATOR MOUNTED VIBRATOR WORK? Modern pile vibrators basically work in the same way. Pairs of high-speed contra-rotating eccentric weights are geared together so as to produce net vertical vibratory forces. The vibrations produced are transmitted to the pile through a powerful hydraulic grip. Consequently the pile is vibrated at the same speed and displacement (or movement) as the gearbox itself.

  • Page 9: Mounting Instructions

    If the excavator is fitted with a quick hitch it will either be necessary to remove it or purchase half a quick hitch and modify to suit the Dawson adaptor bracket. Standard brackets are available for different machine size ranges. Typically, one of these brackets can be adapted to fit a variety of different pin sizes and dipper end widths by using a kit of bushes and spacers.

  • Page 10: Hydraulic Hoses - Layout And Connections

    Hydraulic Hoses - Layout and Connections The EMV hydraulic fittings are metric for the EMV300. The pressure and return lines (already connected to the vibrator) have metric 20 S. The pressure line is usually connected to the bucket ram "extend" circuit and the return line to the bucket ram “retract”...

  • Page 11: Operating Instructions

    5.0 OPERATING INSTRUCTIONS Preparations – before driving/extracting piles. It is the excavator operator's responsibility to ensure that the equipment is functioning and performing correctly and that the EMV method of piling is implemented efficiently. In order to meet this responsibility please note the following points:- Bundles of sheet piles should be set out on the job site so as to minimise the amount of handling and travelling required with the EMV.

  • Page 12: Extracting Piles

    hangs too far away from the clamp when it is raised to the vertical – this will make it difficult to engage the pile in the clamp. Clear all personnel standing in the Danger Area and lift up the pile until it just hangs freely off the ground.
  • Page 13 Clamp the vibrator onto the pile head ensuring that it is level. Ensure all personnel are out of the Danger Area. Start the vibrator and allow the soil to loosen around the pile. Start to lift up the pile. Ensure the pile clutches are not rubbing together. Pay attention to the distortion of the rubber sandwich mounts - under no circumstances should these mounts be allowed to deflect by more than the stipulated amount shown on Figure 1 in section 2.0.

  • Page 14: Maintenance

    • Secure the equipment against unexpected starting during the maintenance process. • The equipment should be inspected by a Dawson technician or by one of their approved distributors once a year or every 1000 working hours.
  • Page 15 their grip on the pile during driving and certainly during extraction. Besides causing a reduction in performance this can become a safety hazard. We define the following wear limit: Hard Jaw Wear Limit - 90% of all teeth on any hard jaw should make contact with the pile and 80% of all teeth should have points with flats no greater than 5x5mm.

  • Page 17: Every 50 Working Hours

    It is recommended that the unit be inspected and serviced by the manufacturer. Apart from undertaking to do the relevant preventative maintenance work and checks as described above Dawson will inspect the structural integrity of the equipment and ensure there are no safety related matters that may go unchecked. Bearings and gears will also be inspected to check for signs of unusual wear or potential problems.

  • Page 18: Trouble Shooting

    Please ensure that troubleshooting, inspection work and repairs are undertaken by suitably qualified personnel. Training can be carried out by the manufacturer or by your local approved Dawson distributor. The following guidelines are intended to assist with basic diagnostics and are not intended to be a definitive list –...

  • Page 19: Emv Clamp Closes But The Unit Will Not Vibrate

    7.2 EMV clamp closes but the unit will not vibrate 7.2.1 Check the base machine operating pressure and flow rate. If the pressure output of the excavator is too low the EMV will not run at all. This is because the sequence valve pressure setting has to be overcome before oil can pass to the drive motor.

Motor Blow- Off Valve 7.4.1.1 Check the drain line hose for obvious restrictions at fittings, filters etc. 7.4.1.2 Check the drain hose for damage – look carefully as the bore of the hose can be crushed even when the outside of the hose looks to be in good order at a casual glance.
