When lifting heavy objects, the hook wire rope should remain vertical. It is not allowed to drag the lifted object diagonally. When lifting heavy objects, the center of gravity should be accurately located and the object should be firmly bound. If there are sharp corners, they should be padded with wooden blocks. Before the heavy […]

(1) The deviation of the actual centerline of the track from the actual centerline of the crane girder shall not be greater than 10 mm. Precise alignment of these centerlines is fundamental. In large industrial workshops where cranes operate continuously, any misalignment here can lead to uneven stress distribution on the crane structure during movement. […]
