The Electric Rotating Crane Hook must be strong enough to withstand the maximum loads involved in the lifting operation, taking into account a certain safety factor to avoid failure due to overloading. The construction of the hook is also crucial. To facilitate loading and unloading of goods, hooks generally have openings, but in some special cases, a closed structure is more effective in preventing objects from slipping during lifting. In addition, anti-slip measures are an important part of the design, and many hooks are fitted with latches or other safety devices to prevent the load from being accidentally dislodged. Finally, as hooks are often repeatedly subjected to heavy loads, fatigue strength is also an important consideration in the design, and the design needs to ensure that the hook is able to withstand the fatigue stresses of the material without cracking or fracturing during its service life. There are also many types and names for hooks, such as crane hook, crane hook safety latch, hook crane, crane hook latch, engine hoist chain and hook, lifting hooks for cranes, crane, swivel hook, automatic crane hook, crane lifting hook, truss lifting hook, heavy duty crane hook.
