Description of explosion proof overload limiter:

The (bqx-b) type explosion-proof overload limiter is applied to explosion-proof gantry crane, explosion-proof electric hoist and other hoisting machinery and equipment used in explosive environment. It is a kind of safety protection to prevent overload of load objects during hoisting operation in explosive environment.
The overload limiter is composed of sensor, operational amplifier, control actuator and load indicator. The overload limiter is composed of sensor, operational amplifier, control actuator and load indicator. The display, control and alarm functions are integrated. When the crane lifts objects, the sensor produces deformation, calculates the tensile force load weight, converts it into signal number, and amplifies the indicator load value through calculation. When the load reaches 90% of the set weight value, an early warning signal will be sent out. When the load weight reaches the rated load, the sensor will send a signal command to cut off the power supply of the lifting mechanism.
