Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of mounting a forklift on a carrier of a truck for transporting a forklift, a mounting jig used for the method, and a forklift.

[0002]

2. Description of the Related Art When there is a forklift only at one of a place where a load is loaded on a truck and a place where the load is unloaded from the truck, it is desirable to carry the forklift together with the load. When mounting a forklift on a truck, securing a space for loading luggage becomes a problem. For this reason, mounting methods that do not occupy the truck bed have been proposed.

As the mounting method, for example, there is a method using a straddle type forklift and a truck provided with a forklift support structure. As shown in FIG. 15, the support structure 9 is provided at a lower rear portion of the bed 31 of the truck 3 and has a fork insertion portion 91 and a main body support portion 92. On the other hand, the forklift 8 is a straddle type as described above, and the front wheel 81 projects forward and is located below the fork 83.

When the forklift 8 is mounted on the truck 3, the fork 83 is inserted into the fork insertion portion 91 of the support structure 9 of the truck 3, and the fork 83 is lowered in this state. The forklift 8 is raised by itself to the main body supporting portion 92 of the forklift. Next, the main body support portion 92 supports the main body of the forklift 8 and prevents the main body from falling.

[0005]

However, the above mounting method has the following four problems. First, since the straddle-type forklift 8 has the front wheels 81 projecting forward, it may interfere with the rear wheels 39 and the tilt of the truck 3 to make loading and unloading difficult. In addition, since the front wheel 81 is located below the fork 83, it may not be possible to drop a load wider than the inner width of the front wheel onto the ground.

Second, when the forklift 8 is mounted on the truck 3, the forklift 8
, The load applied to the rear wheel 39 of the truck 3 greatly increases.
Therefore, in order to keep the axial load of the rear wheel 39 within the allowable range, the load amount of the load may have to be limited.

Third, even if the forklift 8 is mounted on the ordinary truck 3 with the support structure 9 provided thereon, the forklift 8 will protrude significantly behind the rear end 32 of the truck 3. For this reason, domestic regulations such as "the rear overhang is within 60% of the wheelbase" may not be satisfied. Fourth, the forklift 8
When the forklift 8 is mounted on the truck 3, the forklift 8 hides the license plate, lamps and the like of the truck 3, and therefore, it is necessary to change these positions.

In order to solve the first problem, it has been proposed to provide a reach mechanism in the forklift, and to solve the second to fourth problems, it is proposed to provide a notch in the rear of the truck bed. I have. However, these measures still have a problem that truck remodeling becomes large-scale and cannot be applied to a forklift without a reach mechanism.

A method of mounting the above-mentioned straddle type forklift on a truck bed (Japanese Patent Laid-Open No.
JP-A-111153, JP-A-7-101688, JP-A-8-133689, and the like have also been proposed. However, even in this mounting method, there is a case where the cargo handling becomes difficult due to interference with a truck.

In contrast to the above two mounting methods, a method of mounting a counterbalance type forklift on a truck bed (JP-A-58-148198, JP-A-58-148198)
157699, JP-A-7-172229, JP-A-8-26687). The above counterbalance type forklift is suitable for cargo handling in that the front wheels are located rearward of the forks, and thus interfere with trucks. However, when the forklift is lifted by itself and then moved to the truck bed, the operator must manually operate the forklift. For this reason, there are cases where it is difficult to mount the forklift, such as when the bed is inclined or when the forklift is large.

In addition, when a forklift is lifted in a cantilevered state when a forklift is mounted, for example, as disclosed in Japanese Patent Application Laid-Open No. 52-111153, it is necessary to significantly remodel the truck to reinforce the truck. Becomes Also,
For example, when a forklift is mounted upside down as in JP-A-8-26687, a special engine, battery, tank, or the like that does not leak even when rotated by about 90 degrees is required.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned conventional problems, and a method of mounting a forklift on a truck bed by itself without modifying the truck, and a mounting method used for the method. And a forklift.

[0013]

According to the first aspect of the present invention, there is provided a method of mounting a forklift on a bed of a truck for transporting a forklift, comprising: a vertical member extending substantially vertically;
A mounting jig comprising a horizontal member extending in a substantially horizontal direction and a hook provided on the vertical member for engaging a lifting member that moves up and down along a fork lifting mast of a forklift; The horizontal member is placed on the ground in a state facing the forklift, the lifting member of the forklift is engaged with the hook of the vertical member, and then the lifting member is lowered relatively to the forklift. Thereby, the forklift is raised along the vertical member of the mounting jig, then the truck bed is positioned below the forklift, and then the lifting member is raised relatively to the forklift. The forklift is lowered along the vertical member and mounted on the carrier. In the method of mounting to click.

It is most remarkable in the present invention that the lifting member is engaged with the hook of the mounting jig, and the lifting member is moved up and down relative to the forklift. To be mounted on the carrier. That is, the mounting method is performed by lifting and lowering a forklift using the mounting jig and moving the truck.

Next, the operation of the present invention will be described. In the mounting method, the lifting member is engaged with the hook of the mounting jig, and the lifting member is lowered relatively to the forklift. As a result, the forklift starts to ascend by itself from the elevating member. The relative lowering of the elevating member is performed by a distance equal to or greater than the height of the bed of the truck.
The forklift is raised to a height equal to or higher than the height of the carrier.

Next, a truck bed is positioned below the raised forklift. Next, the lifting member is raised relatively to the forklift. As a result, the forklift uses the lifting member as a base point,
It descends on its own and is mounted on the bed of the truck. When the forklift is to be lowered from the truck bed to the ground, operations that are substantially the reverse of the above series of operations are performed.

Next, the effects of the present invention will be described. As described above, in the mounting method of the present invention, the mounting is performed by lifting and lowering the forklift using the mounting jig and moving the truck. Therefore, the truck does not need to be specially modified, and the forklift can be mounted on the truck bed by itself.

That is, by using the mounting jig, the truck can be mounted on the carrier without moving in the horizontal direction only by moving the forklift up and down. The mounting position of the forklift on the truck is determined by the position of the bed of the truck disposed below the raised forklift. Therefore, by devising the stop position of the truck, it is possible to easily mount the forklift at an arbitrary position on the carrier.

The forklift is mounted on the carrier as it is while the entire body of the forklift can travel. For this reason, it is possible to move from the mounted position to an arbitrary position on the bed by self-propelled in the same manner as normal traveling. Therefore, there is no need to make special modifications to the truck or forklift.

Next, as in the second aspect of the present invention, the vertical member of the mounting jig is provided with an engaging member movable on the surface of the fork of the forklift. A stopper capable of engaging with the engaging member is provided at the tip end so as to protrude upward from the surface of the tip portion. After the forklift is completely mounted on the carrier, the fork is engaged with the engaging member. It is preferable that the mounting jig is moved and mounted on the carrier by moving the fork while engaging the member.

That is, for example, the fork is engaged with the engaging member, and the fork is moved up and down along the fork elevating mast, or is tilted in the front-rear direction together with the fork elevating mast (FIGS. 4 and 4). 5). Thereby, the mounting jig placed on the ground is mounted on the loading platform.

In this case, since the mounting jig is also mounted on the carrier, the same mounting jig can be used at the destination of the truck. Therefore, the work of mounting the forklift on the truck using the mounting jig can be further simplified. The mounting of the mounting jig can be performed by the forklift itself by operating the fork as described above. Therefore, the mounting jig can be easily and efficiently mounted on the carrier.

Next, according to the third aspect of the present invention, there is provided a mounting jig used for mounting a forklift on a carrier of a truck for transporting a forklift. A vertical member extending so far, a horizontal member extending substantially horizontally and placed on the ground, and a hook for engaging a lifting member that moves up and down along a fork lifting mast of a forklift, Further, the hook is provided at a position higher than the height of the loading platform in the vertical member, and the horizontal member is connected to the forklift and the mounting member in a state where the lifting member is engaged with the hook. There is a jig for mounting a forklift on a truck, wherein the jig extends to the rear of a center of gravity combined with the jig.

Here, the composite center of gravity refers to the total center of gravity when the forklift and the mounting jig are considered integrally. In using the mounting jig, the horizontal member is placed on the ground with the side member facing the forklift. Next, the lifting member is engaged with the hook, and the lifting member is lowered relative to the forklift. Thereby, the forklift is raised along the vertical member.

Next, the operation and effect of the mounting jig will be described. The hook is provided at a position higher than the height of the carrier in the vertical member. Thus, when the forklift is raised as described above, it can be raised to a position higher than the height of the bed of the truck. Therefore, after the forklift is raised, the bed of the truck can be positioned below the forklift. Therefore, the forklift can be mounted on the carrier by itself without modifying the truck.

The horizontal member extends rearward from a combined center of gravity of the forklift and the mounting jig in a state where the lifting member is engaged with the hook. Therefore, when the forklift is raised along the vertical member, the forklift can be supported without the mounting jig falling over.

As described above, according to the mounting jig, the forklift can be mounted on the truck bed by itself without modifying the truck.

Next, as in the invention as set forth in claim 4, the vertical member of the mounting jig is movable on the surface of the fork of the forklift and is provided at the tip of the fork. It is preferable that an engagement member capable of engaging with the stopper is provided. As the engagement member, for example, a roller or the like can be used.

Thus, as described in the description of the second aspect of the present invention, after the forklift is completely mounted on the carrier, the fork is engaged with the engaging member to move the fork. The mounting jig can be moved and mounted on the carrier.

Next, as in the fifth aspect of the present invention, it is preferable that an auxiliary wheel is provided at the tip of the horizontal member. As described above, when the mounting jig is mounted on the loading platform by the fork, the tip of the horizontal member of the mounting jig is dragged on the ground toward the front of the forklift, It may be dragged on the loading platform toward the rear (FIGS. 4 and 5).

Next, a fork lift mast for a forklift, comprising a vertical member extending substantially vertically and a horizontal member extending substantially horizontally, is provided. A forklift mounted on a forklift truck using a mounting jig provided with a hook for engaging the elevating member that moves up and down along the vertical member, wherein the elevating member comprises: There is a forklift characterized in that it is configured to be able to forcibly lift and lower the forklift.

The most remarkable feature of the present invention is that the elevating member is configured to be able to forcibly elevate and lower the forklift. The elevating member of a normal forklift is configured so that it can be forcibly raised using hydraulic pressure or the like when it is raised. However, at the time of lowering, the lowering member is lowered by its own weight or the weight of the load. On the other hand, the elevating member of the forklift of the present invention is configured to be able to forcibly perform not only the ascent but also the descent using, for example, a backward-acting hydraulic cylinder.

Thus, the forklift can be lifted by using the mounting jig. That is, by engaging the lifting member with the hook and forcibly lowering the lifting member relative to the forklift, the forklift can be raised by itself. Also, by disposing the bed of the truck below the raised forklift, the forklift can be mounted on the bed. Therefore, there is no need to modify the truck.

As described above, according to the present invention, it is possible to provide a forklift capable of mounting a forklift on a truck bed by itself without modifying the truck.

Next, as in the invention as set forth in claim 7, at the tip end of the fork of the forklift, a stopper engageable with an engaging member provided on a vertical member of the mounting jig is provided. It is preferable to be provided so as to protrude upward from the surface of the distal end portion. As a result, the forklift
The mounting jig can be moved by itself by engaging the engaging member at the tip of the fork.

That is, for example, the fork is engaged with the engaging member, and the fork is moved up and down along the fork elevating mast, or is tilted in the front-rear direction together with the fork elevating mast (see FIGS. 4 and 4). 5). Thus, the mounting jig placed on the ground can be mounted on the loading platform. The mounting of the forklift and the mounting jig can be performed by the forklift by a series of operations. Therefore, the mounting jig can be easily and efficiently mounted on the carrier.

Next, as in the present invention, the fork is provided so as to be rotatable in the front-rear direction of the forklift, and the tip of the fork is arranged toward the rear of the forklift. It is preferable that it is constituted so that it can be performed.

Thus, after the forklift is mounted on the truck bed of the truck, the fork can be turned to arrange the tip end rearward (see FIG. 6). Therefore, the forklift is not mounted with the fork protruding from the carrier. In addition, even when the forklift is moved and loaded after mounting, the space on the loading platform occupied by the forklift can be reduced.

Above the fork lifting mast 11, the forklift 1 is held rearward (FIG. 6). Thus, the mounting of the forklift 1 on the truck 3 is completed.

Next, the operation and effect of this embodiment will be described. As described above, in the mounting method of the present invention, the forklift 1 is moved up and down using the mounting jig 2 and the truck 3 is moved (FIGS. 1 to 3). Therefore, there is no need to make any special modifications to the above truck 3,
In addition, the forklift 1 can be mounted on the bed 31 of the truck 3 by itself.

That is, by using the mounting jig 2, the truck 3 can be mounted on the loading platform 31 without moving the forklift 1 up and down without any lateral movement. . The mounting position of the forklift 1 on the truck 3 is determined by the position of the bed 31 of the truck 3 disposed below the raised forklift 1. Therefore, by devising the stop position of the truck 3, the forklift 1 can be easily mounted at an arbitrary position on the carrier 31.

The forklift 1 is mounted on the carrier as it is in a state where the entire vehicle body can travel (FIG. 3). Therefore, it is possible to move to an arbitrary position on the bed 31 by self-propelled from the mounted position in the same manner as in normal traveling. Therefore, there is no need to make special modifications to the truck 3 or the forklift 1.

Since the mounting jig 2 is also mounted on the carrier 31, the same mounting jig 2 can be used at the destination of the truck 3. Therefore, the work of mounting the forklift 1 on the truck 3 using the mounting jig 2 can be further simplified. Further, the mounting of the mounting jig 2 can be performed with the ability of the forklift 1 itself by operating the fork 13 as described above. Therefore, the mounting jig 2 can be easily and efficiently mounted on the carrier 31.

Can be smoothly moved on the carrier 31 or on the ground (FIGS. 4 and 5).

The elevating member 12 is constructed so that not only ascending but also descending can be forcibly performed by the reciprocating hydraulic cylinder 15. Therefore, as described above, the forklift 1 can be lifted by itself using the mounting jig 2.

The fork 13 is provided so as to be rotatable in the front-rear direction of the forklift 1. Thus, after the forklift 1 is mounted on the bed 31 of the truck 3, the fork 13 can be turned to arrange the tip 131 rearward (FIG. 6). Therefore, the forklift 1 is not mounted with the fork 13 protruding from the carrier 31. Further, even when the forklift 1 is moved and loaded after mounting, the space on the loading platform 31 occupied by the forklift 1 can be reduced.

As described above, according to this embodiment, it is possible to provide a method of mounting a forklift capable of mounting a counterbalance type forklift on a truck bed by itself without modifying the truck.

Embodiment 2 In this embodiment, as shown in FIG. 12, a method of mounting the forklift 1 on the front part 311 of the bed 31 of the truck 3 will be described. For example, when other luggage is not loaded on the bed 31 of the truck 3, the forklift 1 is moved from the front part 31 of the bed 31 also from the viewpoint of the stability of the truck 3.
1 is preferable. However, according to the method of the first embodiment, it is easy to place the truck 3 on the rear part 319 of the bed 31 behind the rear wheel 39, but the space between the rear wheel 39 and the front wheel 38 Bed 3

When the forklift 1 is mounted on the front part 311 of the bed 31 of the truck 3 in the same manner as in the first embodiment, the rear wheel 39 of the truck 3 is mounted on the horizontal member of the mounting jig 2. You need to get over 22. That is, FIG.
When the truck 3 is further retracted from the state shown in FIG. 4 and the front part 311 of the bed 31 of the truck 3 is positioned below the raised forklift 1, the rear wheel 39 needs to climb over the horizontal member 22. .

Therefore, in the mounting method of this embodiment, FIG.
As shown by reference numeral 2 in FIG. 2, a trapezoidal step having a gentle inclination is installed so as to get over the horizontal member 22. The step 4 is installed after the forklift 1 is raised by the same method as in the first embodiment (see FIG. 2).

Next, the truck 3 is moved backward, the wheel 39 is then moved over the step platform 4, and the front portion 311 of the loading platform 31 is positioned below the forklift 1. Next, by lowering the forklift 1, the forklift 1 is moved to the front 3
11 Other configurations are the same as those of the first embodiment.

By using the step 4, the rear wheel 39 of the truck 3 can easily get over the lateral member 22. Therefore, according to this example, the forklift 1 can be easily mounted on the front portion 311 of the bed 31 of the truck 3. In addition, the third embodiment has the same functions and effects as the first embodiment.

Embodiment 3 As shown in FIGS. 13 and 14, this embodiment is an example in which the forklift 1 mounted on the bed 31 of the truck 3 is lowered from the bed 31. That is, after the forklift 1 is mounted on the carrier 31 of the truck 3 and transported by the method shown in the first embodiment, the forklift 1 is transported at the destination.
Take down.

In this case, from the state where the forklift 1 and the mounting jig 2 are mounted on the carrier 31 of the truck 3 (see FIG. 6), the mounting jig 2 is first lowered to the ground. When lowering the mounting jig 2, first, the fork 1 held above the fork lifting mast 11
3 (see FIG. 6) is rotated downward to engage the engaging member 24 of the mounting jig 2 (FIG. 13).

Next, the fork lifting mast 11 is tilted forward, and the lifting member 12 is raised to raise the fork 13. As a result, the engaging member 24 is rolled on the fork 13 toward the tip 131,
The mounting jig 2 is moved forward of the forklift 1 (arrow G in FIG. 13). Then, the engagement member 24
Is engaged with the stopper 14 at the tip 131 of the fork 13, and the fork 13 is further raised. As a result, the mounting jig 2 is located outside the loading platform 31.
Is suspended (arrow H).
