Product Description
Drum Assembly It is the core component of the crane hoisting mechanism, mainly used for winding wire ropes or chains to achieve the lifting and lowering movement of the hook. Its performance directly affects the safety, stability, and service life of the crane. Drum assemblies are widely used in various lifting equipment such as bridge cranes, gantry cranes, and tower cranes.
