Description
Stable Transmission · High Torque Capacity · Precise Alignment · Reliable Power Connection
Crane coupling is a key transmission component used to connect the motor shaft, reducer shaft, and drum shaft in overhead cranes, gantry cranes, and hoisting mechanisms. It efficiently transmits torque while compensating for slight misalignment, axial displacement, and vibration between connected shafts.
Manufactured from high-strength alloy steel with precision machining and dynamic balancing, our crane couplings ensure stable power transmission, reduced mechanical wear, and extended service life. They are widely used in single girder cranes, double girder cranes, gantry cranes, and other industrial lifting equipment.
Advantages
Designed for heavy-duty crane applications with strong load-bearing capacity and reliable torque transfer.
Effectively compensates for axial, radial, and angular deviations, protecting motors and reducers from overload stress.
Made of high-strength forged steel with heat treatment for superior hardness and long service life.
Precision machining ensures low vibration, reduced noise, and stable transmission during lifting operations.
Modular structure design allows convenient assembly, disassembly, and replacement of wearing parts.
Application
- Hoisting Mechanism Systems: Connection between motor and reducer in electric hoists and crane trolleys.
- Bridge & Gantry Cranes: Torque transmission between gearbox and drum shaft in workshop and outdoor cranes.
- Port & Metallurgical Cranes: Heavy-duty applications requiring high torque and shock resistance.
- Industrial Production Lines: Equipment requiring stable rotary power transmission and shaft alignment compensation.
