Description

The invention relates to devices for securing long loads on a vehicle, such as trees on forest machines, and can be used in the forest industry.

The purpose of the invention is to improve ease of use.

1 schematically shows a device with an open loop, a general view; figure 2 - the same, with a closed loop.

The device (figure 1) contains a hollow beam 1 mounted on the vehicle 2, the cable loop 3,. formed by a working cable, passed through block 4, fixed with its ends on the mechanism 5 for tightening the loop 3 (winch) and, for example, on T1 means of transport 2, the mechanism for opening the loop, made in the form of hydraulic cylinders 6, which are also racks of the beam 1 and secured along its edge.

The cavities of the hydraulic cylinders 6 are connected via channels cx with the cavity of beam 1, which is filled with working fluid and provided with an airtight elastic tank 7 with compressed gas, which opens the cable loop 3.

Cable loop 3 in the open position is supported by hydraulic cylinder rods b by means of cable

five

otezhk 8, fixed at one end movably on the cable loop 3, and the other fixed, for example, on beam 1, and projected through the blocks

9, which are equipped with rods of hydraulic cylinders 6.

The device works as follows.

For fastening wood 10 or

The bundles of trees (Fig. 2) of the cable loop 3 are tightened by the tightening mechanism 5. Decreasing along the perimeter, the cable loop 3 tightens towards the center of the tree 10 beds

tether cable 8 supporting it. Cable wires 8, having a constant length, move their rods into the cylinders 6. Rods squeeze out part of the working fluid from

the cavities of the hydraulic cylinders 6 through the channels d into the cavity of the beam 1 and compress the gas in the elastic tank 7.

Before opening, the cable loop 3 is loosened. The compressed gas in the elastic container 7 forces a portion of the working fluid from the cavity of the beam 1 through the channels a in the cavity of the hydraulic cylinders 6 and returns their stems to the initial position. Itoc hydraulic cylinders 6 by means of cable delays 8 open the cable loop 3, ensuring the loading of the next gear in it. Then the cycle is repeated.
