Hydra Crane Axle Bolt is a type of fastening component used in the axle assembly of a hydra crane. Axle bolts are essential for securing the various parts of the axle system, which is crucial for the crane’s mobility and stability. Axle bolts secure the axle components, such as wheel hubs or track assemblies, to the crane's chassis. They bear the loads transmitted through the axle system, including the weight of the crane and the loads being lifted.
