For vertical lifting of freely suspended, heavy, bulky loads, hoisting equipment (or hoists) works in conjunction with overhead cranes and workstation cranes. Their lifting capacities depend on their construction. Their travel is directed by an operator, either manually or with a wired pendant station or wireless controls. Typical applications include helping operators in manufacturing, warehousing and construction to lift loads in support of production or storage activities, loading and unloading, or one process to the next.
