Hook for improving safety prevents damage

Hook in cranes would have the power of side pulling puts added stress on ropes and other crane components and sets the stage for hazardous load swing when we wholesale them from overhead crane supplier China. And the zbcranes hook centering feature automatically eliminates side pull of loads.

What’s the principle for the crane’s hook? Actually, hook centering is based on measurement of the rope angle. If the angle exceeds a preset value when the hoist starts to lift a load, the hook will work for that to keep the safety of the crane. Generally speaking, side pull occurs when a hoist lifts a load that is not placed directly underneath it. Side pull from China gantry crane manufacturer causes extra stress on different crane components such as the wire rope, rope guide and drum. It can also cause uncontrollable movements of the load, which is a safety hazard for the surrounding area. The crane operator turns on hook centering with the selector switch on the radio controller. After that, the feature is always on in every lifting situation.

At the same time, movement upwards is limited. When the crane and high quality hydraulic lifting platform and load are vertically aligned, lifting continues normally.
