Claims

[Claims for Utility Model Registration] 1. A lift plate 21 that is movable up and down and consists of a main plate 22 and an auxiliary plate 23 is provided at the rear or side of the vehicle, and the main plate 22 is provided on the vehicle body 1 in a horizontal direction. It can be folded freely around the axis X-X. At the same time, the auxiliary plate 23
is the second axis Y-Y perpendicular to the 11th idle line X-X.
In the lifting device which is foldable/foldable with respect to the main plate 22 about the center, the cylinder 6 and the arm 12 whose one end is pivotally connected to the shaft 7 at the upper part of the cylinder box 4 rotate about the pivot shaft 11. A locking pin 36 is fixed to the center of the link 9 that is integrated with the arm 12 of the parallel link, and a locking hook 34 that rotates about the pivot 11 is provided, and one end of the gas cylinder 39 is attached to the locking hook 34. A lifting device characterized by being pivotally connected above a pivot 11 and having the other end pivotally connected to an end surface of a shaft 7 of a cylinder 6. 2. The lifting device according to claim 1, in which the shaft 38 of the gas cylinder 39 is attached to the side surface of the cylinder box 4. 3. A locking pin 36 is fixed to the central part of the cylinder 6 whose one end is pivotally connected to the shaft 7 at the upper part of the cylinder box 4, and the arm 8 which is a parallel link that rotates by the arm 12.
A locking hook 34 that rotates around 0 is provided, one end of a gas cylinder 39 is pivoted above the pivot shaft 10 of the locking hook 34,
The elevating device according to claim 1, wherein the other end is pivotally connected to the side of the cylinder box 4. 4. Attach the locking piece 27 fixed to the main plate 22 of the elevating plate 21 to the first
The end face of the locking piece 27 comes into contact with the catch seat 29 provided on the extension line of the axis X-X and fixed to the cylinder box 4 when the lifting plate 21 is at the horizontal lift limit position, and the lifting plate 21 is folded and raised. The elevating device is characterized in that when the elevating device is lifted, it is locked to a locking piece 31 fixed to the side of the catch seat 29.
