Description

This invention extends the pallet, attaches auxiliary wheels and expands the loading surface, so that it is possible to transport long objects by low lift and load a large amount of articles at a time, thereby improving workability and stability. Do not decrease

Conventional low lift pallet size is limited by the length of the fork, and there was no long pallet, so long items could not be transported and the load capacity was limited. Since stable storage and smooth moving operation are not compatible, special transport vehicles, pallets, and other equipment are used, which reduces the efficiency of cargo handling work and increases equipment costs.

Problems to be solved by the invention

The first object of the present invention is to improve the carrying capacity by low lift so that long objects and a large amount of articles can be carried at a time without deteriorating work efficiency and stability.

A second object of the present invention is to easily move a pallet with auxiliary wheels by a low lift.

A third object of the present invention is to enable safe storage of a pallet with auxiliary wheels carrying a load.

Means for solving the problem

In order to achieve the first object, the present invention provides a pallet with an auxiliary wheel according to claim 1, wherein the auxiliary wheel is operated by an attached arm using the vertical movement of the fork portion of the low lift. It is characterized by lifting.

The invention according to claim 2 is characterized in that a bottom frame is provided on the bottom side of the pallet with auxiliary wheels in order to achieve the second object, and the movement of the unitary object is made by floating the fixed wheel in the low lift fork portion. To do.

According to a third aspect of the present invention, an arm or a mechanism for operating an auxiliary wheel is attached to a pallet with an auxiliary wheel to achieve the third object, and the auxiliary wheel of the pallet with an auxiliary wheel is operated by a low lift fork portion. It is characterized by taking in and out.

Form of actual invention

Hereinafter, embodiments of the present invention will be described with reference to the drawings. In FIG. 1, the external appearance of the pallet 1 which is an example of invention is shown.

In the pallet 1 with auxiliary wheels, an arm 12 is attached by a support shaft 9 between the stacking surface 3, the three vertical frames 2 supporting the same and the vertical frame, and auxiliary wheels 10 are attached to the arms 12. A bottom frame 11 on which the fixed ring 6 of the low lift fork portion 5 is placed is formed on the bottom surface.

The arm 12 shown in FIG. 5 is supported by a support shaft 9 and is not fixed so that it can freely move up and down. An auxiliary wheel 10 is attached to the tip of the arm 12, and a low lift 4 is attached to the tip of the opposite side. A plate for pressing the fork 5 and a push-up arm 13 are formed.

When the pallet 1 with auxiliary wheels shown in FIG. 1 is used, an article is placed on the loading surface 3, and the low lift 4, which is a cargo handling equipment, extends between the push-up arm 13 of the arm unit 12 and the bottom frame 11. The fixed wheel of the fork part 5 is rotated and inserted in the traveling direction.

For example, as shown in FIG. 2, the low lift 4 includes a pair of elongate forks 5 that protrude in parallel from the main body 14 and horizontally hold them, and is provided with a main steering wheel 7 provided on the main body 14 and the tip of the fork 5. The fork 5 can be lowered by pulling the lever 8 to release the hydraulic pressure.

Now, as shown in FIG. 7, the tip of the pair of forks 5 of the low lift 4 is rolled from the fork insertion port of the pallet, and the fork tip is inserted from the fork insertion port to the bottom frame 11.

Then, the pair of forks 5 is relatively lifted by pulling the low lift hydraulic lever 8 many times around the support shaft, and the push-up arm 13 of the arm 12 is pushed up as shown in FIGS.

When the fork 5 is raised and the arm 13 is pushed up and the arm 13 is pushed up, the auxiliary wheel 10 of the arm 12 is lowered to the ground by the lever principle. At this time, the fulcrum of the arm 12 is on the support shaft 9 and the pallet 1 with auxiliary wheels is It will not float.

Further, as shown in FIGS. 8 to 9, the fork 5 is lifted to move the fulcrum from the support shaft 9 to the auxiliary wheel 10 at the arm tip. The support shaft 9 of the arm 12 is raised. As a result, the support shaft 9 is replaced with a force for pushing up the pallet 1 with auxiliary wheels.

At the same time, a force for the fixed wheel 6 of the fork to push down the bottom frame 11 acts, and this force acts to keep the distance between the pallet 1 with the auxiliary wheel and the auxiliary wheel 10 at the end of the arm as shown in FIG. The pallet 1 with auxiliary wheels is lifted. Thus, the low lift 4 can be used to lift it safely and easily.

Further, since the fixed ring 6 at the tip of the fork 5 of the low lift 4 is supported by the bottom frame 11, the fixed wheel 6 at the tip of the fork 5 also floats together with the pallet. As a result, the pallet with auxiliary wheels is lifted by the auxiliary wheels 10 coming out of the pallet with auxiliary wheels and the low lift steering main wheel, so that it can be easily transported rather than difficult operability like a towing vehicle.

In addition, as an example of the present invention, there is a method of using the fork 5 of the low lift 4 as shown in FIG.

As for transportation, the fork of the low lift forcibly spreads the push-up frame and the bottom frame to apply pressure to the contact part, and the bottom frame has an angle on the insertion side as shown in FIG. The fork cannot be removed from the attached pallet.

After transporting, pull the low lift release lever to release the hydraulic pressure and lower the fork. As a result, the arm 12 of the pallet with auxiliary wheels is lowered and the auxiliary wheel 10 is raised, so the pallet with auxiliary wheels is lowered. The auxiliary wheel is housed in the pallet together with the arm, and the entire pallet is grounded to the ground, so that the original stable storage of the pallet can be performed.

Effects of the embodiment

As described above, according to the present invention, in the pallet with auxiliary wheels, it is possible to operate the auxiliary wheel and lift the pallet without difficulty even when the load is loaded by the function of the low lift fork part. A pallet longer than the fork length can be easily lifted and moved easily. Moreover, since the wheel can be stored, it can be stored safely.
