Rope drums are a key element of lifting drives – they are used to wind steel rope and transfer the pulling force from the drive to the hoist or grab. Structurally, they are a steel cylinder with ends and grooving adapted to the rope diameter and winding direction to ensure its correct seating and minimise wear.
The design of the drum diameter, length, and groove profile is based on the required lifting height, winding method, and operating conditions. The drum includes secure anchoring for the free end of the rope.
A correctly designed rope drum extends the life of the rope, ensures smooth lifting operation, and contributes to the safe operation of the entire crane.
