And the rear end surfaces 8 and 8 are wrapped. By the operation of the two hydraulic cylinders 3, 3, the rear end surfaces 8, 8 of the lift arms 6, 6 are slid and guided on the inner surfaces of the rear guide posts 14, 14, respectively. The slide posts 9, 9, 11, 11 are guided by the inner surfaces of the respective guide posts 13, 13, 14, 14, so that the lift arms 6, 6 move up and down while maintaining a horizontal state. The two pallet support bars 10, 12 installed between 6, 6 move up and down at the same time.

An upper pallet 15 on which a vehicle is mounted is provided on the front and rear pallet support bars 10 and 12, and the upper pallet 15 is provided with the pallet support bars as the lift arms 6 and 6 move up and down. It moves up and down while maintaining a horizontal state by the vertical movement of 10, 12.

On the other hand, in the pit 1, a lower pallet 16 on which a vehicle is mounted is provided on the upper surface. The lower pallet 16 has front links 17 and 17 and rear links 1 at substantially four corners corresponding to the upper pallet 15.
The upper pallet 15 is suspended from the upper pallet 15 so that the lower pallet 16 is flush with the ground when the upper pallet 15 is at the highest position. When the upper pallet 15 moves up and down through the vertical movement of the pallet support bars 10 and 12 due to the operation of the hydraulic cylinders 3 and 3, the lower pallet 16 moves up and down in conjunction with that. Here, the vertical distance of the upper pallet 15, that is, the hydraulic cylinders 3, 3
The width of expansion and contraction of the piston rods 5, 5 is substantially equal to the depth of the pit 1, and the lower pallet 16 is moved up and down in the pit 1 from the bottom surface 2 to a position flush with the ground. The upper pallet 15 moves up and down.

In the present embodiment, the front link 17 is formed by connecting two flat bars to each other with their ends overlapped and axially connected to each other. It is configured to bend toward.

The pallet 16 is attached to the rear side portion. Lock holes 21 and 22 are formed on the rear cylinders of the outer cylinders 19 and 19 and the inner cylinders 20 and 20, respectively, when the upper pallet is in a horizontal state. A lock lever 24 having a claw 23 engaging with the lock holes 21 and 22 is rotatably supported on the side surface of the lower pallet 16 behind the lower ends of the inner cylinders 20 and 20. The lower end of the lock lever 24 is a lock spring 25
Therefore, in the normal state, the claw portion 23 is locked by the lock holes 21 and
The rear portion of the lower pallet 16 is suspended from the outer cylinder 19 via the lock lever 24 by engaging with the lower pallet 16.

On the side of the lower pallet 16 in front of the lock lever 24, there is provided a release lever 28 which has a roller 26 at its lower end and which rotates when the roller 26 comes into contact with an inclined surface 27 provided appropriately. The upper end of the release lever 28 and the lower end of the lock lever 24 are connected by a wire 30 via a buffer spring 29 having a higher elastic force than the lock spring 25. In this embodiment, the inclined surface 27 is buried at the bottom of the pit 1.

When the lower pallet 16 descends to the bottom surface 2 of the pit 1 due to the structure of the rear link 18, the roller 26 comes into contact with the inclined surface 27 and rolls, and the release lever 28 pivots. The wire 30 is pulled against the pullback force of the lock spring 25. As a result, the lock lever 24 is released, and the integration of the inner cylinder 20 and the outer cylinder 19 is released.

[0031] Of the lift arm guide surfaces 31, 31, which are the inner surfaces of the rear guide posts 14, 14 and guide the rear end surfaces 8, 8, of the lift arms 6, 6, the lowermost of the lift arms 6, 6 are lowered. In the position, the lift arms 6, 6 are inclined and the rear end faces 8, 8 of the lift arms 6, 6 are tilted.
Pockets 32, 32 into which the lower ends 8a, 8a of the bosses fit are formed. The rear guide posts 14, 14 receive the pallet support bars 10, 12 when the lift arms 6, 6 reach the lowest position, and stop the lowering of the lift arms 6, 6. A stopper (not shown) is provided.

The pocket 32 is approximately 12.
As a result, the lift arms 6, 6 are lowered to the lowest position, and the pallet support bar 12 is received by the stopper and stopped (at this time, the upper pallet 15 and the upper pallet 15). The lower pallet 16
Are at the lowest position), and at the same time, the lower ends 8a, 8a of the rear ends of the lift arms 6, 6
The guide loses the guide due to the presence of the pocket, and fits into the pocket 32 while being inclined. At this time, the lift arms 6, 6
The front link 6 connecting the upper pallet 15 and the lower pallet 16 is bent at the front end portions 6a, 6a side of the front pallet. At this time, the lower pallet 16 is in the lowest position, that is, the pit 1

The rear side of the upper pallet 15 rotates upward while the extension 8 is extended.

By the above mechanism, the vehicle entrance side of the upper pallet 15 is tilted downward at its lowermost position.

On the other hand, when the upper pallet 15 is tilted, the piston rods 5 of the hydraulic cylinders 3, 3
When the extension 5 extends, first, the front ends 6a, 6a of the lift arms 6, 6 are lifted and the front link 17 in the bent state becomes linear, and the extended rear link 18 is restored to the original state. The upper pallet 15 returns to the horizontal state. Then, the lift arm 6,
The rear end surfaces 8 of the rear guide posts 6
The upper pallet 15 rises while being kept horizontal by being guided by the inner lift arm guide surfaces 31, 31. At this time, the front side of the lower pallet 16 begins to slightly lift due to the action of the front link 17 and the release lever 28 separates from the inclined surface 27, so that the claw 23 of the lock lever 24 is moved by the action of the lock spring 25. Lock holes 21 and 2 that are formed in the outer cylinder 19 and the inner cylinder 20 that constitute the rear link 18 and that are compatible with each other.
2 is engaged. As a result, the rear side of the lower pallet 16 is suspended from the outer cylinder 19 via the lock lever 24, and the lower pallet 16 moves up together with the upper pallet 15.

A folding board 33 is connected to the front end 15a of the upper pallet 15 using a hinge. The riding plate 33 has a structure in which a front member 34 and a rear member 35 are connected by a hinge 36, and the upper plate 15 is folded upright on the front end 15a thereof in accordance with the tilt of the upper plate 15; Pallet 15
