WITH

Sl

The invention relates to a lifting and transport equipment, namely, traverses for cantilever lifting and transporting cargo, and can be used to spread the area served by a lifting device.

The purpose of the invention is to increase the convenience of operation.

FIG. 1 shows a traverse console without load; in fig. 2 - the same, with a load; in fig. 3 shows section A-A in FIG. one.

The traverse contains a carrier beam 1, an element for attaching it to the hook of the lifting mechanism and a balancing mechanism connected to it.

The hook-and-hold element is a rigidly connected to the floor bar, 1 vertical upright 2 with roller 3 at the upper end.

The balancing mechanism includes a counterweight 4 with roller 5 displaced with possibility of shifting 1ep1 relative to the heats of beam 1 and the flexible element associated with it fixed to one end of the middle part of the bearing beam 1 and the other

Bending the rollers 5 and 3, to the additional counterweight 7. By means of the cable 8, the counterweight 4 through the blocks 9 installed at the ends of the carrier beam 1 is connected to the load gripping body 10 by means of a chain hoist 11.

To limit the displacement of the counterweight 4 and adjust the crosshead, the carrier beam 1 is equipped with adjustable limit stops 12.

When the load 13 is taken by the load gripping body 10, the counterweight 4 by cable 8 through blocks 9 moves along the carrier beam 1. This increases the horizontal component of the forces acting on the counterweight 4 from the flexible element 6 from the weight of the additional counterweight 7, and the latter moves upwards along the vertical rack 2.

At the moment when the horizontal forces acting on the counterweight 4 are balanced, the displacement of the counterweights 4 and 7 ceases.

When the load is removed from the load gripping body 10, the counterweight 4 under the action of the additional counterweight 7 returns to its original position.

Claims (1)

A CONSOLE LOAD-BEARING CROSS, containing a supporting beam, an element connected to it for hanging a load-lifting mechanism on a hook, a balancing mechanism, including a counterweight placed with the possibility of movement relative to the beam and connected to the latter a flexible element fixed at one end in the middle of the supporting beam mounted on the ends of the supporting beam are blocks enveloped by a cable, one end of which is connected to a load-gripping body, and the other to a counterweight. characterized in that. that, in order to increase the convenience of operation, the balancing mechanism is equipped with an additional counterweight and a roller fixed on the nerve counterweight, the element for hanging on the hook of the load-lifting mechanism is a vertical rack rigidly connected to the supporting beam with a roller at the upper end, while the flexible element is stocked on the counterweight rollers and racks and is fixed at the other end to an additional counterweight, the first counterweight being mounted on a support beam with the possibility of horizontal movement in l it, and the additional movable along the vertical upright.
