Foot-mounted Load Limited Switch for Electrical Hoist
The crane limiter is the overload protection device of the crane. The overload operation of the crane is one of the important reasons for the accident of the crane. The excessive stress generated by the overload operation can damage the transmission parts, break the steel wire rope, deform the structure and fail the braking, resulting in the downward deflection of the main beam of the crane, cracks and desoldering of the upper cover plate and web plate of the main beam, It will also cause major accidents such as boom and tower body breaking, and also cause motor overload and motor burning of electrical system. Therefore, overload is invented as protection.
The foot-mounted overload limit switch, once the overload is confirmed, a high-frequency alarm will occur and the rising power supply will be automatically cut off, so as to protect the safety of people and mechanical devices. It is an ideal supporting product of the crane
