1、 Limiter

The limiter is an important component of the safety protection device for cranes, which can limit the displacement of machinery in walking, lifting, expansion and contraction, thereby avoiding accidents such as collisions and falls of equipment.

2、 Overload protector

Overload protector is a safety protection device that can automatically cut off the power supply when the equipment is overloaded. Once the crane is overloaded, it will immediately activate the overload protector, automatically cut off the power supply, and protect the machinery and personnel from danger.

3、 Height limiter

Height limiter is a reliable safety protection device mainly used for height control of cranes. It can accurately measure the height of the equipment and automatically stop the operation of the machinery when the limited height is reached.

4、 Crane height limiter

The lifting height limiter is a special type of height limiter used to control the lifting height of a crane. It can accurately measure the lifting height of the equipment and automatically stop the operation of the machinery when the limited height is reached.

5、 Lifting torque limiter

A lifting torque limiter is a safety protection device used to control the lifting torque of a crane. It can accurately measure the lifting torque of equipment and automatically cut off the power supply when the limit value is exceeded, protecting the safety of equipment and personnel.

6、 Walking safety device

The walking safety device is one of the important components of the crane safety protection device, which can achieve safety control during the walking process. It can measure the walking speed and position of the equipment, and automatically stop the operation of the machinery when abnormalities occur.

The above are common safety protection devices for cranes. Enterprises need to configure and maintain these devices reasonably when using cranes to ensure the safety of equipment and personnel.
