The jib crane is used mainly as an aid in the operation of an overhead crane and is installed in the same room, but one level lower. This type is very popular in enterprises. This is explained by its versatility, convenience and efficiency.

In the industry, there are mainly two types of jib cranes - a mobile and a stationary jib crane. Mobile is a console mounted on a vertical frame. The frame, in turn, rests on two wheels with a separate drive. Such a crane is fixed on the wall, it can only move along it. The movement takes place along special guides using an electric mechanism.

The second type is a stationary cantilever crane. This type is attached either to the wall of a building or to a vertically standing tubular or box-shaped column. In this case, the column is placed on the foundation. In the event that the console can turn, this type is called a "cantilever-slewing crane".

Movement of goods is carried out with the help of a hoist fixed on the console andmoving along it. It can move both with the help of a mechanism installed on it itself, and with the help of a cable traction leading to the console winch. In the second case, it is possible to move loads with a large range of speeds. The console itself is moved manually, with the help of a rope, most often fixed at its end, or by an electric motor. In the latter case, the device will be called "cantilever electric crane".

If a column is used as a support, the crane can have two arms. It is called double shoulder. Single-arm (single-girder) cranes are lighter and less expensive. The two-arm can lift loads of greater weight and can withstand a greater load.

Expediency of using different types of cranes

  1. In the event that it is necessary to lift loads that are not too heavy, it is better to use a jib crane with a manual hoist and manual rotation of the console. Such devices are most often very convenient, as they are easy to operate.
  2. If you need to lift and move heavy loads, it is better to use a crane with electric traction. In addition, it is not bad if it is equipped with a hoist (an electric winch for moving the hoist).
  3. If special stability is required for any production reasons, it is best to move loads using a double-arm cantilever crane.

In addition, the industry produces this equipment and to order, if necessary, its work in anyspecific conditions. At the same time, the length of the console, its angle of rotation, the height of the load, the total load capacity of the crane can be increased.

The jib crane is often used to service warehouses, construction sites, small production areas, special posts, etc. Based on many years of experience in the use of this technique, it can be said with confidence that it can be simply indispensable in various industries - mechanical engineering, loading and unloading terminals, machine shops, etc.
