Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a structure for disposing balance weights in a cargo handling vehicle such as a forklift truck.

[Prior art]

In a cargo handling vehicle such as a forklift truck, a balance weight is disposed at the rear of the vehicle in consideration of vehicle balance when cargo is placed on the front.

For example, as shown in FIG. 3, a balance weight 7 is fixed to the rear of a cargo handling vehicle 90 in a forklift truck 9. Also.

An engine hood 92 provided with a seat 93 is provided in front of the balance weight 7.

As shown in FIG. 4, the balance weight 7 is attached to the hook 71 of the balance weight 7 by an engaging portion 95 provided on the vehicle 90 at the rear of the engine hood 92.
At the same time, attach the lower part to the bolt hole 72. bolt 8
6 is fixed to a bracket 94 of a vehicle 90.

Further, in front of the balance weight 7, as shown in FIG. 4, there is a radiator 81 for cooling the engine cooling water.
An exhaust muffler 82 and the like are provided. Note that the reference numeral 85 in the same figure is a tow bar.

[Problem to be solved]

However, the radiator 81. Exhaust muffler 82
When carrying out maintenance services such as protection and repair, the balance weight 7 must be removed from the vehicle 90.

This maintenance service is often performed for the radiator 81. That is, the ventilation section of the radiator tends to become clogged with dirt and the like, and such clogging reduces its heat dissipation efficiency and tends to cause overheating of the engine.Therefore, regular maintenance is required.

However, this balance weight 7 is used to improve vehicle balance when loading and transporting cargo on the fork 901.
It is made from a heavy iron ingot (approximately 100 to 300 kg). Therefore, when removing the balance weight 7, it is necessary to lift the balance weight using a hoist or other lifting device.Furthermore, after maintenance, the balance weight 7 must be lifted again and the hook 71. It must be fixed by the bolt 86, thus
Conventional balance weights require a lifting tool such as a hoist to remove and install, and involve the risk of operating two heavy objects.

In view of these problems, the present invention does not require a lifting tool during maintenance, etc., and can be safely removed. The purpose is to provide a balance weight for cargo handling vehicles.

[Means for solving problems]

The present invention relates to a cargo handling vehicle having a balance weight disposed at the rear of the vehicle, wherein the balance weight is pivotally mounted to the vehicle so as to be rotatable in a substantially horizontal direction. It is in.

What should be noted in the present invention is that the balance weight can be rotated substantially horizontally. Here, being able to rotate in the horizontal direction refers to a state in which it can be opened and closed not only completely horizontally but also slightly upwardly or downwardly, that is,
As shown in the embodiment, the rotatable state, which is a state in which the balance weight can be opened and closed in the lateral direction, includes a structure in which the balance weight is pivoted to the vehicle in a pin-point type.

[Action and effect]

In the present invention, the balance weight is pivotally mounted to the vehicle so as to be rotatable in a substantially horizontal direction.

Therefore, the balance weight can be opened and closed laterally.

Therefore, if the balance weight needs to be removed, such as during maintenance of the radiator in front of the balance weight, the balance weight can simply be opened laterally.

According to the present invention, it is possible to provide a balance weight that does not require a hanging tool and can be safely removed.

〔Example〕

Regarding the balance weight of the cargo handling vehicle in this example, the first
This will be explained using FIG.

In this example, a balance weight 1 is arranged at the rear of a forklift truck 9 so as to be horizontally rotatable.

That is, as shown in FIG.
At the rear left end of vehicle 90.

A concave plate 61 having engaging pieces 611, 611 is fixed by welding. Also, the engagement pieces 611, 621 of the double concave plate 61.62 are similarly welded and fixed to the rear right end of the vehicle 90 with the concave plate 62 having the retention pieces 621.621.
face towards the rear of the forklift truck and have pin holes 612, 621 for inserting pins 21, 22, respectively.

On the other hand, the balance weight 1 is made of a heavy iron ingot, and has a convex engaging portion 11 at its front left end and a similar convex engaging portion 12 at its right end.

The double-convex engaging portion 11.12 has a pin hole Ill, 121 for inserting a support pin 21.22.

Thus, the balance weight 1 has its right convex engaging portion 12 fitted into the concave plate 62 on the vehicle side, and is pivotally attached by the support pin 22 (FIG. 1).

Moreover, the balance weight l is as shown in FIG.

It is normally closed, and at this time, the convex engaging portion 11 on the left side of the balance weight 1 fits into the concave plate 61 on the vehicle side and is fixed by the support pin 21 so that it cannot be opened.

Note that the head of the support pin 22 is designed so that it cannot be easily pulled out.

A fixed piece 25 is fixed.

Next, radiator 81. When removing the balance weight 1 for maintenance etc. of the muffler 82,
As shown in FIG. 1, the left support pin 21 is removed and the balance weight l is opened to the right, thereby making it possible to easily repair the radiator 81 and the like.

As mentioned above, when opening and closing the balance weight 1, it is preferable to arrange the opening/closing aid 3 below the balance weight 1, as shown in FIG. It has a flexible roller 31. According to the auxiliary tool 3, it is possible to smoothly open and close the balance weight 1, and also to support the balance weight 1 and maintain the weight balance in the lateral direction of the vehicle during opening and closing. Also, assistance! 43 has a roller, and
It is preferable to use a format that can be jacked up.
