Hoist rope exchange



Alatas was commissioned to conduct a hoist wire rope exchange on an LHM280 crane in Ireland, supplying all necessary equipment for the task.


Routine maintenance involves changing hoist ropes to uphold the reliability and safety of crane hoist operations.

Job Scope:

  • Position the boom for maintenance.
  • Lower winches until limits engage, then lower further to ensure one turn is on the winch.
  • Secure hoist ropes on the roof using bulldog clamps and chain blocks.
  • Remove hoist ropes from the winch and store clamps inside the machine house.
  • Set up rope stands in front of the chassis and position two sets of ropes.
  • Ensure the rope reels from the bottom of the new hoist rope reel.
  • Remove rope sockets from the hook, one by one, and bind the rope to the opening.
  • Cut rope sockets from the old hoist rope and weld a chain link on the end.
  • Attach new and old hoist ropes with hammerlocks.
  • Lower hoist ropes over the back of the counterweights and attach them one by one to a suitable pulling vehicle, maintaining radio contact.
  • Secure the new hoist rope on the machine house roof with bulldog clamps and chain blocks once it reaches the winch.
  • Repeat the process three more times until all hoist ropes are at the winch.
  • Attach the new hoist ropes to their respective winches, ensuring all rope tails are equal for a consistent rope level.
  • Attach all clamps to the winch, and then attach all new hoist ropes to the hook.
  • Raise the boom, ensuring the correct seating of the hoist ropes on the winches.
  • Check the level of the hook once it is off the ground.
  • If the hook is not level, use a spirit level and a straight edge located on top of the rope anchors to record levels and necessary adjustments for each rope.
  • Adjust the ropes as necessary with the boom in the maintenance position based on measurements.
  • Raise the boom again and repeat the leveling process if the hook is still not level.
  • Test hoisting up and down to ensure proper functioning.
  • Remove all equipment from the site and clean the working area.
  • Conduct a final briefing with the client.
  • Complete timesheets.
