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.
