Application

This Lebus split drum shell is designed for crane winch systems, mainly used for hoisting and luffing mechanisms of mobile cranes, crawler cranes and portal cranes.
It is applied in heavy-duty outdoor scenarios including ports, mines, wind power hoisting and large infrastructure projects for orderly winding and load-bearing of steel wire ropes.
The split structure allows direct replacement of damaged rope groove segments without replacing the entire drum, ideal for machinery maintenance and equipment retrofitting projects.
Custom manufacturing is available based on client drawings to match heavy lifting equipment with different rope capacities and wire rope specifications.
