The workshop overhead crane limiter switch
The limiter switch is an essential safety device for a workshop overhead crane and is used to limit the ascent height of the picking device. When the spreader of the workshop overhead crane rises to the limit position, the limiter switch will automatically cut off the power supply to prevent the lifting device (such as the hook) from continuing to rise, causing the hook collide with crane body. After the wire rope shrinks completely, if the electric hoist or winch continue to work and pull, will broken wire rope and the heavy object will fall down.
The workshop overhead crane limiter switch combines the trip switch with the convex-concave puller, simple structure, sensitive movement, can effectively suppress the occurrence of heavy object falling accidents and ensure the crane working site safe production. Therefore, the workshop overhead crane must be Install limiter switch.
