Abstract
A lifting equipment is provided. The lifting equipment may include a working assembly, a safety assembly, and a shaft assembly. The working assembly may include a working fastener. The working fastener may be spirally connected to the shaft assembly. When the shaft assembly rotates the working fastener may move along the shaft assembly. The safety assembly may comprise a limiting component. The limiting component may be connected to the working fastener. A portion of the safety assembly may be in located a space between the limiting component and the working assembly.
Claims20
A system comprising:
- a working assembly including a working fastener;
- a safety assembly including a safety fastener;
- a shaft assembly;
- and
- a load lifting mechanism including a first fastener surface, wherein:
- the working assembly is configured to support the load lifting mechanism when the working assembly is coupled to the load lifting mechanism;
