As a compact and lightweight lifting device, the stage hoist is widely used in performance-related operations such as stage construction, equipment hoisting and scene layout, thanks to its portability, flexibility and stable load-bearing capacity. However, during actual operation, due to factors such as operational errors, limited on-site space and accidental slipping of hands, the stage hoist will inevitably collide with stage trusses, equipment enclosures, the ground and other objects, or even fall accidentally.
When a stage hoist sustains a minor collision, a comprehensive and meticulous visual inspection and functional test should be carried out on the device first. Focus on checking whether key components such as the hoist shell, hook, chain and gear cover have deformation, dent, scratch or crack. Meanwhile, manually pull the chain to check if the lifting and lowering movements are smooth, if the chain engages and retracts properly, and if there is any abnormal noise inside the device.
If the inspection shows that the hoist has no obvious deformation in appearance, no internal parts are loose, displaced or damaged due to the collision, and all functional tests are normal, it indicates that the collision has not affected the load-bearing structure and transmission system of the device. In this case, the hoist can be put back into use after simply cleaning the dust and stains on its surface.
