Description

The invention relates to construction and installation work, in particular to devices for slinging lengthy structures, mainly column type apparatuses.

The purpose of the invention is to improve performance by balancing the loads on the load-lifting mechanism.

FIG. 1 shows a device for slinging lengthy structures in FIG. 2 shows section A-A in FIG. 1, in FIG. 3 shows a section BB in FIG. 2; in FIG. A, the link of the bandage in FIG. 5 is a diagram of the lifting of a column-type apparatus with a device for slinging lengthy structures} in FIG. 6, node I in FIG. five.

The device for slinging lengthy structures consists of a bandage 1 and a flexible line 2, to cover the tie band 1. Bandage 1 consists of individual links 3 each. The link 3 includes a plate 4, on which on the outer side is hinged TC roller 5 and roller bearings .6. To prevent the sliding of the flexible sling 2 from the band 1 with a vertical position of -4

The scientific research institute of the lifted structure 7 is welded to the latter by two mounting nipples 8 consisting of pipe 9, ring 10, plugs 11, fins 12, rollers 13 and sleeves 14. Plates 4 are hingedly connected to each other. The rollers 5, bending around the flexible sling 2, are made concave in a longitudinal section, which prevents the flexible one from sliding.

Sling 2.

Device for slinging lengthy structures works as follows.

The band 1 is attached to the raised structure with 7 ropes 15. Then a flexible sling 2 covering the band 1 and mounting nipples 8 sling a device for slinging lengthy structures on crane hooks.

In the process of lifting a lengthy design in the event of uneven operation of lifting equipment, the flexible sling 2 freely flows over the rollers 5 of the brace and the rollers 13 of the assembly

fittings, resulting in automatic balancing of the entire system, which in turn ensures uniform loading of lifting equipment and the stability of the load in space.
