Abstract

The invention relates to lifting devices. The purpose of the invention is to simplify the design. The device comprises a carrier beam 1 with spring-loaded gripping bodies 2 connected by cables 5 with crane hooks. In the middle part of the beam on a vertical support 6 there is a chain 8 with a sinker 10 at one end and with a ring 9 for hanging on the crane hook. The position of the chain is regulated by a latch 11. Depending on the chain length, the tension of the cables 5 and the position of the gripping bodies V2, 2, or so on changes.

The invention relates to a lifting and transport engineering.

The purpose of the invention is to simplify the design, with

Fig, 1 shows the device, a general view; 2 is a view A of FIG. 1.

The device comprises a carrier beam 1, the gripping bodies 2 placed at its ends, spring-loaded springs 3, JQ one of which can move in the guides 4. Cables 5 are connected to the gripping bodies to hang onto the body of the load-lifting mashine. B. The middle part of the beam contains a support 6, in which 5 an opening 7 is made, through which the chain 8 is passed. At one end of the chain 8 there is a ring 9 for attachment to the body of a lifting machine, and at the other end is a weight 10. The chain can be fixed in different positions of the support retainer 11.

The device works as follows.

Cables 5 and chain 8 are hung on the three-legged sling of the roof. In dependence
