On ropes attached explosive, United conductor with the interior of the truck.The truck pulls to the towed car and maneuvering with the help of mover 2 in a horizontal plane and driven Coulter 5 to move the lever in a vertical plane, the loop of the first wire 10 is installed in the cavity of the throat boxingthe ago. When this capture 7 overcomes the force of the stopper 8 and moves the clamp 9. When the clamp from the capture cable 10 falls into the groove of the grip, the width of which is larger than the diameter of the rope. The first cable is connected with the machine and disconnected from the device. Upon further movement of the tractor back the cable is tensioned, the tension of the rope drag exceeds the strength of the element 13, the latter is triggered, and the middle part of the first rope is released. The connection of the second cable 12 with the machine is the same way. If necessary, eliminate the fire from the outside of the machine and the towing device of the machine handle cleaning agents, who served in the area of the hitch through the hose 18.To tow in forward motion of the tractor from the middle part of the rope is passed along one of the sides of a vehicle, secured it decaying elements, and the ends of the cables, the opposite terminals are connected with the rear hooks of the tractor. Coupling cables tractor with hooks evacuated machine is the same as when towing in reverse. Release the cables from the boards after coupling with the machine is carried out by turning the body of the tractor in the direction opposite to the placement of the cables due t is Yahweh efforts during the evacuation of the machine used block sheave pulleys and winch tractor (Fig.3).In the initial position, the lever is mounted on the vomer. On the lever fixed block sheave pulleys 15 by collapsing element 13. The winch cable 14 skipped around the block and connected with the hook 3. The cables 10 and 12 one ends connected to the hooks 16 of the polyspast, and the other ends connected to the grippers 7 and 11 and secured them with brakes. The middle part of the rope attached to the tractor decaying elements 13.After alternately snapping loops both cables to the tow hooks of the machine and release the middle part of the rope the same as the above tractor continues to move back. When the tension of the cables 10 and 12 of the collapsing element 13 block variable geometry mechanism is triggered, because the power cable tension exceeds the strength of the destruction of the element. The block is released from the lever and is connected strained ropes with hooks on the machine. Further movement of the tractor back going with the omission of the levers and the unwinding of the winch cable. Unwinding the winch is due to the inclusion for the grant of a rope and exceeding the tension of the tow rope relative to the holding force of the winch cable in the body of the tractor.
