What are the three types of jib cranes？

There are three types of jib cranes: column type, wall-mounted type and balance jib crane.

①Column jib crane is a cantilever crane composed of a column and a cantilever whose cantilever can rotate around a fixed column fixed on the base, or the cantilever is rigidly connected to the rotating column and rotates together relative to the vertical centerline in the base support. It is suitable for occasions where the lifting capacity is not large and the operating service range is circular or fan-shaped. It is generally used for clamping and transporting workpieces such as machine tools.

Column-type jib cranes mostly use electric chain hoists as the lifting mechanism and operating mechanism, and rarely use electric wire rope hoists and manual hoist. Rotation and horizontal movement operations are mostly manual, and electric is only used when the lifting capacity is large.

②The wall crane is a cantilever crane that is fixed on the wall,or a cantilever crane that can run along an elevated track on a wall or other supporting structure.

Wall travelling jib cranes are used in workshops or warehouses with large spans and high building heights, and are most suitable for frequent hoisting operations near the walls. Wall travelling cranes are mostly used in conjunction with the girder or bridge cranes above, serving a cuboid space near the wall, responsible for lifting light and small objects, and the overhead bridge cranes for large ones.

③Balance jib crane uses the principle of four-bar linkage mechanism to form a balance system between load and balance weight, and can use a variety of spreaders to flexibly and easily lift loads in three-dimensional space. The balance jib crane is light and flexible, and is an ideal lifting equipment for lifting small items. It is widely used in machine tool loading and unloading in factory workshops; workpieces in processes, automatic lines, production lines; sand box lifting; parts assembly; and Stations, docks, warehouses and other occasions.
