• Check the proper rotation of rope drum with and without load. Pay attention to running sound of rope
drum bearings and check that the rope drum does not touch with machinery end plates.
• Lower the hook to the ground.
• Check the grooves of the drum.
#
Healthy grooves are smooth and do not have sharp edges. In case of doubt, unwind some more
rope from the drum and compare the used grooves with unused grooves.
• Lubricate the drum surface.
• Check the drum axial locking parts (8) for wear. Replace the axial locking part with new one.
• Lubricate the groove in the drum, in which the axial locking part is located.
• Lubricate the drum bearing.
