Light and small lifting equipment mainly refers to hoisting machinery with only one lifting device, including jacks, tackles, electric hoists, manual hoists, and trucks.
Cranes refer to hoisting machinery that can be lifted vertically and transported horizontally, such as bridge cranes (also called cranes or overhead cranes), truck cranes, and tower cranes.
According to the structure, cranes are divided into two types: bridge cranes and jib cranes. Cranes, metallurgical cranes, gantry cranes, and cable cranes belong to bridge cranes, portal cranes, tower cranes, truck cranes, crawler cranes, tire cranes, and cantilever cranes.
According to the operation mode, cranes are divided into fixed and mobile types. Tower cranes and cantilever cranes belong to fixed cranes, bridge cranes, tire cranes, crawler cranes, and railway cranes belong to mobile cranes. Mobile cranes are divided into two types: tracked and trackless. The bridge crane is a track type, and the crawler and car type are trackless.
Lift refers to a hoisting machinery with a fixed position, a fixed lifting line, a wire rope traction, a slide rail restriction, and a cage. Including various elevators, winches, winches, etc.
