Description

The invention relates to devices for securing lengthy 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 simplify the design of the device.

Figure 1 shows the proposed device, a General view; figure 2 is the same, side view; on fig.Z - the device with the inclined racks.

The device comprises a turntable 2 mounted on the vehicle 1 with stands and a lever 3 which is spring-loaded relative to the vehicle by a spring 4, a loop 5 formed by a working cable passed through the guide block 6 and fixed at one end on the mechanism 7. the winch, and the second on the beam 2, and the loop opening mechanism, made in the form of hydraulic cylinders 8 with blocks 9 and cable straps 10. The sleeves of hydraulic cylinders 8 are simultaneously strut beams 2..

The working cable bends around -balku 2 relative to its longitudinal axis. This gives him the opportunity, using a stack of 11 trees as a support, to turn the beam 2 and stretch the spring 4 under the action of tightening the loop 5. The minimum amount of bending around the beam 2 by the working cable

should be such that the end of the working cable is fixed on the beam from the bottom, at the point of intersection with its vertical axis. This allows the working cable to turn the beam 2 through an angle ensuring the horizontal cylinders 8 are in horizontal position.

The device works as follows.

As the pack of 11 trees (fig. 3) is set, one end of the working cable, fixed on the pulling mechanism 7, is wound onto the drum. Loop 5 compresses bundle 11. The second end of the working cable, mounted on beam 2, using packet 11 as a support, under the force of tightening loop 5 rotates beam 2. with hydraulic cylinders 8 and lever 3. The spring 4 is extended, the struts are horizontal, and fit, for example, into the frame of the vehicle 1 ,. and exit from the danger zone of their contact with package 11.

Thus, it is possible to freely rotate the stack 11 relative to the vehicle 1 during its turns.

When unloading the bundle II, the cable loop 5 is loosened and the spring 4 by means of the lever 3 returns the beam 2 with the legs to its original position. Cable pull 10 under the hydro-. The cylinders 8 stretch the cable loop 5 and release the pack 11.
