The Role of Drum Couplings in the Lifting Industry

The core function of drum couplings in the lifting industry is transmitting power and compensating for deviations. They connect the crane's drive motor (or reducer) to the drum, ensuring stable power transmission for lifting/lowering heavy loads while adapting to displacement errors during installation and operation.

Its key roles can be broken down into two points:

1. Core of Power Transmission: Acting as a "power bridge", it accurately transmits the torque from the drive unit to the drum, driving the drum to rotate and realize the winding/unwinding of the steel wire rope. This is the direct power link for the crane to achieve lifting functions.

2. Deviation Compensation & Protection: uring the operation of lifting equipment, the axes of the motor, reducer and drum may shift (such as radial or angular deviation) due to installation errors or load deformation. The coupling can absorb these deviations through its own structure (e.g., elastic components), avoiding damage to parts caused by hard impact and prolonging the service life of the equipment.

I can help you translate the core technical parameter list for drum coupling selection (mentioned earlier) into English, which will include key indicators like torque, speed, and deviation compensation. Do you need me to do that?
