Description

one

The invention relates to equipment for mounting equipment, in particular to balancing beams for lifting telescopic equipment and structures with two cranes.

The known balance bar is equipped with a main beam, equipped with a device for hanging on crane hooks, and an additional beam with slings for lifting cargo 1.

However, when re-adjusting the traverse, there is a need for time-consuming manual operations.

The purpose of the art is to simplify the traverse design.

The goal is achieved by the fact that the additional beam is hinged directly on the main beam, and the slings are of variable length.

FIG. 1 shows the proposed traverse, general view; in fig. 2 - the same, when raising the apparatus of smaller diameter.

The balance bar includes a beam 1 with axles 2 for attaching the slings 3 going to the hook holders of the cranes. In the center of the beam 1 on the axis 4 with the possibility of rotation in the vertical plane, an additional beam 5 is installed, at the ends of which axis 6 is installed to secure, neither the lines 7, going to the lifting device 8.

Depending on the dimensions of the lifted load, the lines 7 are designed to be of various lengths.

Balance traverse works as follows.

With the help of the slings 7, the apparatus 8 is attached to the beam 5, and with 10 using the slings 3, the beam 1 is connected to the hook holders of the crashes. Including the cargo tackles of the cranes, they raise the traverse, and as the straps 7 are tensioned, the beam 5 rotates relative to the horizontal beam 1. The beam 5 rotates until the lines 7 and the device 8 are in a vertical position without tilting, which further lifting apparatus 8.

If it is necessary to lift the apparatus 20 of a larger (smaller) diameter with the same traverse, lines 7 are changed, respectively, reducing (increasing) their length. Re-adjustment of the remaining elements of the traverse is not required.
