Overload limiter is a safety protection device designed specifically for lifting heavy objects on lifting weights. The hoisting equipment shall be protected by a preset Angle. This ensures that the crane is safe to use.

Working principle:

The protection level is IP44.

Do not need to remove the wire rope when installing, do not need to change the crane mechanism structure, adjust to most steel wire rope diameter specification.

The structure is simple, stable and reliable, easy to install, easy to operate, no influence on hoisting height.

Accurate, sensitive, consistent good, non-mechanical wear, long-term usage accuracy remains unchanged.

The reaction speed is fast, 0.5 s inside can realize judgement and action.
