The crane is usually equipped with many protection devices to ensure crane safety and avoid potential dangers.
The load lifting limiter is a crane safety device to restrict the lifting weight of the crane. If the crane is overloaded, the device will cut the lifting electrical loop and give the alarming message, since the overloaded lifting weight not only damages the crane itself but also leads people around the crane into danger. Therefore, in order to guarantee the safety of the crane, operators should predict the lifting weight in the beginning, prepare a large tonnage crane or use two cranes to work together.
The lifting height limiter is another crane safety device on the crane hook to protect the safety of the crane. When the lifting hook rises to the limited height, the device will automatically cut power and remain enough safety height to ensure the lifting braking has enough safety distance. This device is well-designed by engineers after taking various cases into consideration. When the operator incorrectly operates the crane, the journey inhibiting device will automatically cut the power of the crane's running mechanism to stop the crane operation immediately, ensuring the safety of the operator and the crane.
What's more, it is also necessary to make regular inspections and maintenance for the crane, making sure that all devices of the crane can run smoothly. Before using the machine, a comprehensive crane safety check should be conducted to see whether the crane components are all well placed and if there is rust or wear of the components. Regular clean is also needed to avoid the accumulated dust.
