The important role of the overload protection device in cantilever cranes

Thread Content

To ensure the safety and reliability of cantilever crane operation, relevant overload protection devices must be installed before each crane operation. Under normal circumstances, the overload protection devices for cantilever cranes are divided into automatic stop type and comprehensive type. The automatic stop type means that it can stop the lifting operation on its own when the lifting weight exceeds the load capacity. Additionally, in the case of integrated types, where the lifting capacity is much greater than 90% of the rated lifting capacity, the jib crane will emit alarm signals and visual warning indications. At this point, if the lifting weight exceeds the rated lifting capacity, the lifting operation will stop automatically. It is understood that these two types of cantilever cranes can ensure that the crane operates in a safe manner. Furthermore, the overload protection device can also ensure dynamic performance by accommodating the actual overload of the crane as well as its normal operation. At the same time, it is also capable of automatically performing specified functions as well as automatic safety functions.
