It has a large operating space and is mainly used for vertical and horizontal transportation of materials and installation of building components in house construction. It is an indispensable and important equipment in construction projects.
[0003] When using a tower crane to suspend construction materials, the materials need to be fixed and suspended by a hook. In order to prevent the materials from falling off the hook, a spring lock is provided on the hook to give the hook a self-locking function. However, the spring lock on the hook generally moves inside the hook and then resets to achieve the self-locking function. Therefore, when the rope or hanging ring passing through the hook is large in size, the spring lock will be blocked from resetting inside the hook, affecting the normal use of the hook and the normal operation of material transportation. Therefore, further improvements can be made. Utility Model Content
