The invention relates to lifting equipment.

The purpose of the invention is. increased reliability. FIG. 1 shows the traverse, the general view in FIG. 2 is section AA. Fig about 1; in fig. 3 - Air Force B in FIG. 2 ,,

The traverse includes a carrier beam 1, a stand which is made telescopic and includes an upper 2 and lower 3 guides, the suspension assembly 4 to the lifting mechanism is mounted on the upper guide 2 racks. The lower end of the lower guide 3 is pivotally connected to the middle part support beam 1. At one end of the latter, a load gripping body 5 is installed, and at the other bypass unit 6o the traverse contains a polyspast comprising two blocks 7 and 8 mounted on a rack. On support beam 1 it is mounted to move Or is it a counterweight 9 connected to one end of the cable 10, which goes around the side block 6 and the blocks 7 and 8 of the chain hoist. At the same time, the other end of the cable 0 is fixed on the Traverse support beam equipped with two spring-loaded arms 11 and 12, located symmetrically with respect to the rack, while one of the arms is completed. Of adjustable length, two parallel-mounted drums 13 and 14, rigidly connected with their axes 15 and 16, which are pivotally mounted on a carrier beam 1 o. A ratchet wheel 17 is rigidly fixed on the oi and one of the drums. There is a flexible control body 18 which is attached to the end of the beam 1 connected to the load gripping body 5, the ends of t g 11 and 1 2 are pivotally connected to the lower 3-post guide and supporting beam .1, and the stop 19 of the ratchet wheel 17 is rigidly connected to the lower guide 3. The cable 10 is stored on the drums 13 and 14, and the upper block 7 of the chain hoop is mounted on the upper direction 2

Traverse works as follows

The traverse is suspended on the hook of the load-lifting machine. The load is suspended in the load gripping body 5 ,, At the beginning of the lifting, the chain hoist lengthens and the counterweight 9 moves until the carrier rotates

beams 1 and traverse trim. When the carrier beam 1 is rotated, spring-loaded rods 11 and 12 operate, while the drum with the ratchet wheel 17 interacts with the stop 19 and stops the traverse. The elongation of the chain hoist stops, and the balanced traverse is transported with the load to the unloading place. When unloading, the traverse is operated through the flexible control member 18, turning the traverse by a certain angle. The angle is selected on the basis that the force in the cable 10 of the polyspast is less than the component weight of the weight of the counterweight 9 After turning at this angle, the stop 19 leaves the ratchet wheel 17 and the counterweight returns to its original position
