Bracket-swing cranes

Bracket crane  - reliable assistant in production

Electric bracket crane is a popular type of lifting equipment. The construction is made of steel and has a form of a vertical column to which a jib is mounted in a horizontal position. There are two main types of such constructions: bracket-swing on the column and bracket-swing wall-mounted constructions. The swing-type crane is permissible for use both indoors and outdoors.

Swing jib crane: design features

The structure has a form of a column on which the jib is mounted. Its characteristics depend on the nature and quantity of cargo, length and the maximum height that it can rise on. The boom section can be boxlike or I-beam.

The jib is equipped with a swivel mechanism, which is operated manually or by means of a geared motor.

Constructions of this type are 6 meters high. The angle of rotation of the jib can be 180 °, 270 ° or 360 °, and the boom length is up to 8 meters. The carrying capacity of the mechanism is variable: 0.5 t, 1 t, 2 t, 3.2 t, 4 t, 5 t, 6,3 t, 8 t and 10 t. The structure is equipped with a load-lifting device that does not allow lifting more than the lifting structure of this type is provided.

It can be used for work of A3 - A5 type - light and medium load. General purpose industrial designs are made, as well as special designs for work in explosive conditions. They are capable of withstanding ambient temperatures from -40 ° C to +40 ° C, no matter whether indoors or outdoors. It is possible to set a limit for the angle of rotation of the jib and the departure of the electric hoist.

The easiest modification of this design is a jib-crane - a triangular bracket with blocks that can be mounted on a wall, column or another plane. Its load-carrying capacity does not exceed 5 tons, so the price for the crane-jib is set to the minimum.

The electric telpher deals with lifting and moving of cargo. It allows moving heavy loads at a compact size of the lifting structure. Electric motors with a conical rotor and planetary gears participate in the process. The electric drive can be made in such variations:

  • 1 or 2-speed contactor with a magnetic starter;
  • thyristor;
  • frequency-response with a smooth start;

The mechanism is activated when an alternating three-phase current is applied at a frequency of 50 Hz and with a voltage of 220 V or 380 V. It is fed by a flexible copper cable.

The construction is controlled remotely via a hanging console or a radio control system. You can make the design for individual requirements. For example, for work in seaports, hazardous industries, etc.

How to choose the swing crane

The portable bracket crane is selected according to the following parameters:

  • amount of electricity consumed;
  • ambient temperature when it is used;
  • reach of the boom; the angle of rotation;
  • carrying capacity;
  •  the surface area of operating space.

 As a rule, it is chosen for work in the production of light and heavy industry, warehouses, and workshops, especially for construction or transportation companies.
