There are three types of cantilever cranes: column type, wall type, and balance crane.
① Column cantilever crane is a cantilever crane composed of a column and a cantilever that can rotate around a fixed column fixed on the base, or the cantilever is rigidly connected to the rotating column and rotates relative to the vertical centerline in the base support. It is suitable for occasions where the lifting weight is not large and the operating service range is round or fan-shaped. Generally used for loading and transporting workpieces such as machine tools.
Column cantilever cranes mostly use electric chain hoists as the lifting mechanism and operating mechanism, and seldom use wire rope electric hoists and hand chain hoists. Rotation and horizontal movement are mostly manual, and electric is used only when the lifting weight is large.
②The wall crane is a cantilever crane fixed on a wall, or a cantilever crane that can run along an elevated track on a wall or other supporting structure.
Wall cranes are used in workshops or warehouses with large spans and large building heights. They are most suitable when lifting operations are frequent near the wall. Wall cranes are mostly used in conjunction with beam or bridge cranes above, serving a cuboid space near the wall, and are responsible for lifting light and small objects. Large ones are borne by beam or bridge cranes.
③Balanced crane, which uses the principle of four-bar linkage to make the load and balance weight form a balance system, which can use a variety of spreaders to flexibly and easily lift loads in three-dimensional space. The balance crane is light and flexible. It is an ideal lifting equipment for lifting small items. It is widely used in the loading and unloading of machine tools in the factory workshop, work-pieces in the workshop, automatic lines, production lines, sand box lifting, component assembly, and Various occasions such as stations, docks, warehouses, etc.
