[0002] The hoisting device applied to building engineering refers to various types of equipment for lifting and hoisting operations at construction sites. These devices come in a wide variety of types and configurations, and mainly include cranes, spider cranes, hoists, hoisting pulleys, and rigging. Most of the cranes used at construction sites are tower cranes, which can carry heavy loads and efficiently complete hoisting operations.

[0003] Generally speaking, high-rise buildings under construction are usually equipped with construction elevators to facilitate worker access. Although the cabin in the construction elevator has been lengthened, it is still unable to transport steel pipes longer than the cabin. Therefore, when transporting steel pipes, it is still necessary to use a tower crane to deliver the steel pipes to the top of the building. However, this delivery method requires workers to be present at the top of the building and to transport the steel pipes to the construction floor, so some construction workers will hoist the steel pipes to the outside of the designated floor to reduce the transportation time of the steel pipes. However, this practice is extremely dangerous because there is an unmeasurable gap between the steel pipe-carrying basket and the floor. If workers do not take adequate safety precautions, they may easily fall or the steel pipe may fall to the ground. Therefore, we provide a hoisting device facilitating unloading to solve the above problems. SUMMARY
