    We strongly recommend that this publication be read and understood by all staff concerned before the hammer is operated in the field. BSP products are engineered for reliable operation and long life in normal conditions of use; reliability and life can be extended by careful and regular maintenance following the recommendations in the maintenance section of this manual.

    3 minutes the rate reaches 25 blows per 25mm (inch) the hammer must be stopped immediately. iii. Maximum rake – when used with established BSP raking configurations 1 : 3 (18°) PLEASE NOTE: NEVER START THE HAMMER UNTIL THE HAMMER ROPE IS SLACK. THE ROPE MUST REMAIN SLACK DURING ALL DRIVING OPERATIONS, or IF A SLEDGE IS USED IT IS ALWAYS KEPT IN CONTACTWITH THE HAMMER USING THE PULL DOWN WINCH.

  • Page 24: Regular Maintenance

    REGULAR MAINTENANCE 4.1 Transport Whenever the hammer is configured for transport from site to site, the ram must be secured to the cage to prevent unintentional movement. An eyebolt must be screwed into the ram through a hole in the side of the cage. Provision is made for this on either side of the hammer to suit the mounting configuration.
  • Page 25 4.3 Hydraulic Contamination It is important that no dirt or debris finds its way into the hydraulic system. In the short term the operation of the hammer is unlikely to be effected, but the gland seals will quickly become damaged causing leakage and damage to the piston rod.
  • Page 26 The oil should be warmed to at least 5°C prior to hammer operation to prevent cold oil bypassing the return filter b) If circumstances allow, the oil in the BSP HP125 should be warmed to 20°C by circulating oil over the relief valve at 50% flow.

  • Page 27: Regular Maintenance Schedule

    4.5 Regular Maintenance Schedule The following checks are a guide to the frequency with which the machine should be inspected when in regular use. If it has been standing idle for some time all points need to be checked out before re-com- mencing work.
  • Page 28 4.6 Dolly Selection & Replacement Selection of Cushion Material BSP recommends the use of a Cast Nylon material which has been specifically processed suitable for piling use. To protect the pile from damage during driving the combination of Elastic Modulus and assembly thick- ness should not result in a stiffness of greater than 3.4 MN / mm.

  • Page 29: Vibration Damper

    4.7 Vibration Damper A polyurethane damper is retained in the cage bottom adapter to absorb the recoil from the pile and prevent damage to the hammer. The damper should be replaced if it becomes miss-shapen or burns out due to overheating. To access the damper remove the hammer by removing the M48 bolts securing the hammer to the cage bottom adapter.
