Monkey Hoist Trolley

The trolley is the mechanism that moves the hoist along the bridge girder of a crane. The hoist is moved horizontally along the top or underside of the bridge girder to position it above a load (Figure 1, Motion 2). There are three types of trolleys: low headroom, normal headroom and double girder trolley.Hoists are a type of assistance that can make people move quickly from one place to another in the hospital or at home. The hoist allows for more mobility and more independence for disabled people in the comfort of their own homes.
