Abstract

FIELD OF THE INVENTION The invention relates to a lifting and transport machinery, namely, cross-arms for lifting articles with an offset center of mass. The purpose of the invention is to expand operational capabilities by increasing the range of sizes of lifted loads. The traverse includes two cargo beams 2, 3 connected with spacers 4 for cargo suspensions 5 connected by struts 1, supporting beam 7, mounted for movement along cargo beam 2 and fixing by means of a pin 8 and provided with assembly lines 9 with sling 10, an additional supporting beam 12. The supporting beams 7 and 12 are moved along the cargo beams 2 and 3 so that the center of mass of the lifted load is approximately located near the vertical passing through the hook 11. 1 sludge. b (L S

position

The adjustment of the traverse to another size of the lifted loads is carried out by moving the support by means of the pin 8. Supporting beams 7 and 12 along the cargo

The living beam 7 is provided with slinging nodes 9, to which the slings 10 are attached, which are hung on the hook 11 of the lifting mechanism.

The yoke is provided with an additional support beam 12 connected to the load beam 3 by means of the clips 6 for movement along the beam.

Cargo beams 2 and 3 are placed at an angle of 45-90, and supporting beams 7 and 12 are parallel to the corresponding cargo beams 2 and 3 above them.

The traverse is provided with a device for fixing the position of the supporting beams 7 and 12 relative to the cargo beams 2 and 3, containing chains 13, fixed on the supporting beams 7 and 12, and brackets 14, fixed on the cargo beams 2 and 3, interacting with chain links 13.

Traverse works as follows.

Lanyards 10 are hung on hook 11 by lifting the mechanism. The traverse is placed over the load 15. The cargo suspensions 5 are installed in the sockets 4. The pin 8 fixes the position of the socket 4 on the cargo beams 2 and 3. Supporting beams 7 and 12 are moved along the cargo beams 2 and 3 so that the center of mass of the lifted load

approximately, the support beam was parallel to

ticking through the hook 11 of the lifting mechanism.

Lifting gears with a load of 15 over the zenpay. ni) ii of this cage 6 supporting beams 7 and 12 move along the load 1 m beams 2 and 3 until the center of gravity of the load is on the vertical, passing through the hook 11 of the load lifting mechanism. Thereafter, further movement of the collars 6 along the load beams 2 and 3 is stopped. The link of the chain 13 is hooked onto the bracket 14, fixing the position of the supporting beams 7 and 12 relative to the cargo beams 2 and 3. Thereafter,

lifting the load and feeding it to the desired position.

The re-adjustment of the traverse to another size of the lifted cargo is carried out by moving the supporting beams 7 and 12 along the cargo

beams .2 and 3 so that the center of mass of the lifted load is on a vertical line passing through the hook of the lifting mechanism.

The use of the proposed cross bar for lifting structures of various sizes and configurations with a displaced center of mass makes it possible to reduce the labor costs for slinging the lifted loads and expand the operational capabilities of the cross bar.
