Disassembly:

In some cases, it can be possible to pull the new rope on to the hoist by using the old rope and a
cable-sock. Pay special care when using this practice. Make sure there is no risk for personal
injuries and assure the new rope does not get damaged.
Re-assembly:
• Check that the new rope is compatible with the hoist. Check the rope certificate to determine whether
the rope is of the correct diameter and breaking load.
• Unroll the cable (when delivered as a roll) or use a cable-reel stand (when delivered on a drum).
Follow the principles as set out in standard ISO 4309.
• Fasten the rope end to the rope drum with the rope clamps.
