Load testing is an important comprehensive indicator for testing the quality and safety performance of lifting machinery products. Through load testing, not only can the deformation of the metal structure of the crane be detected, such as the deflection value of the bridge crane, but also the effective condition of the crane safety device, such as the overload limiter and the action protection of the torque limiter of the tower crane under rated load state, can be detected. In short, load testing is extremely important for checking the structural load-bearing capacity of cranes and their components, welding and cracking conditions, permanent deformation, loose connections, effectiveness of safety devices, and damage that affects the performance and safety of cranes.
