While a standard electric chain hoist is either coupled with a trolley or suspended from a beam by a hook, the P-MH-5 is a stationary type that has metal clamps for mounting it onto a frame or other structure.
Since it can be mounted directly onto a structure (such as a frame), it can be used as a hoist at a multistory parking lot, as opening/closing gear for a door, as a hoist for a crab crane, and for many other applications.
