When loading, unloading and demoulding, the building template can be lifted upwards by hooking the lifting hook by the lifting mechanism. The common situation in actual construction is that a worker self-makes a steel bar S-shaped lifting hook, and the lifting hook is convenient to construct and has the following problems: 1. the unhooked Shi Mu square holes are deformed because the wood has small rigidity and is easy to deform due to uneven stress; 2. the S-shaped lifting hook is convenient to unhook when being hooked with a machine, but potential safety hazards of unhook exist in the lifting process. 3. Many lifting hooks need to be matched with a steel wire rope for use, and irregular construction is easy to cause.
