Description

[Detailed Description of the Invention] Conventional retsu car vehicles have a small crane device attached to the loading platform, and the crane device lifts the front or rear part of the vehicle and tows it. As a result, since the vehicle is lifted by a crane, the vehicle being towed cannot be towed in a stable manner. Also, its lifting power was limited, making it unsuitable for towing large vehicles. The present invention aims to eliminate such drawbacks and provide an excellent tow truck that can tow even large vehicles quickly and safely.

The gist of this invention is that the front end of the main beam 2, which extends from the front of the loading platform 1 toward the rear and is bent downward at the rear to a position slightly higher than the tire contact surface on the outside of the loading platform, is connected to the front end of the main beam 2. A hydraulic cylinder 4 for rotating the main beam is provided between the rear part of the main beam and the loading platform 1, and an arm 5 extending outward is provided as a pivot at the bent lower end of the main beam. At the same time, a hydraulic cylinder 6 is provided to raise the arm, and a tire support 8 with tire holders 7, 7' attached to both left and right ends is pivotally mounted 9 at the center of the arm, and a winch device 10 is further installed. It is in the car that will be prepared.

In addition, in the figure, 11 is the bent part of the main beam 2, and 12 is the bent part of the main beam 2.
13 is a locking hook at the end of the wire of the winch device 10, 14 is a tire mounting rotatably attached to the tire pedestals 7, 7', 16 is a vertical rod attached to the rear end of the main beam 2, and 17 is a A stopper pin 18 is a rod guide stand, 19 is a tire of a car to be towed, and 20 is a pivot of the arm 5.

In this device, when not being towed, the arm 5 is erected by the hydraulic cylinder 6 and stands upright at the rear end of the cargo platform 1, as shown by the solid line in Figures 1 and 2, so that the tow truck can be operated. It is designed to be safe and trouble-free. When towing a car, the hydraulic cylinder 6 is activated to rotate the arm 5 about the pivot 20 and tilt it down until the tip of the arm touches the ground (see imaginary line in Figure 1).

Next, the winch device 10 is activated by hooking the locking hook 13 of the winch device 10 to a part of the chassis or body of the vehicle to be towed, and winding the wire and using the locking hook 13 to lock the vehicle towed. The tire 19 is moved toward the loading platform 1, climbed up the tire board 14, and seated on the tire pedestals 7, 7'. Next, when the hydraulic cylinder 4 is activated, the main beam 2 rotates counterclockwise around the pivot 3 with the tire 19 placed on the tire pedestals 7 and 7', and the arm 5 is lifted and the traction The tire 19 of the car to be used is lifted. left and right tires 1
9 is held in a balanced state at the same height and left and right by a tire cradle, and by mooring a car towed by a winch device 10 with a wire, the car being towed can be stably supported and towed. It is something. Moreover, these operations are carried out using the hydraulic cylinder 4.
6 and operation of winch device 10 and winch device 10
Since the only work required is to lock the locking hook, it can be carried out quickly and safely.

As described above, the present invention has the effect that even large vehicles can be towed quickly and safely by using the above structure.
