5.30.3 Assembly

Disassembly:

• Adjust (or by-pass) the lower limit switch so that the rope can be fully unwound from the drum

• Lower the hook onto a stable working-platform.

• Remove the rope guide, see section “Rope guide, Assembly” for details.

• Pull, with a gloved hand, the rope down from the drum, until the last turn.

• Switch OFF the power supply to the crane.

• Extract the rope anchorage from the overload device, see section “Rope anchorage, Assembly” for

details and remove the rope from the anchorage.

• Pull the rope out from the hook block and return sheaves.

• Remove the rope clamps from the drum and remove the rope.

# 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.
