Description

[Detailed Description of the Invention] The present invention relates to a forklift in which a freely rotating pad is attached to the bent portion at the base of the fork to ensure speed and reliability of work.

In conventional forklifts of this type, it required a high degree of skill to use the fork to raise and prop up packages lying on the ground. That is, by operating from the driver's cab, first clamp one end of the package with a fork while adjusting the clamping force, then raise the fork and clamp the other end of the package that is in contact with the ground. This was only possible by swinging the package as a fulcrum and moving the vehicle forward while tilting the mast back and forth as necessary. For this reason, the work is troublesome and time-consuming, and the process lacks reliability. In addition, there was also the problem that slippage occurred between the fork and the packaged item, causing damage to the packaged item.

This invention was developed in view of the above-mentioned shortcomings of the conventional forklifts, and a normal forklift has a fork installed in front of the mast to place cargo and pallets for loading cargo. However, by providing a pad that can freely rotate at the base of the fork, we have created a forklift that can be operated easily and reliably without the need for conventional skilled techniques. That is.

Embodiments of the present invention will be described below with reference to the accompanying drawings.

In FIG. 1, a forklift 1 according to the present invention moves a vehicle body 2, front wheels 3, rear wheels 4, cab 5, mast 6, clamp control mechanism 7, fork 8, and vertically moves the clamp control mechanism 7 and fork 8. and a tail cylinder 10 for tilting the mast 6 forward or backward. The fork 8 has two forks (8a, 8) as shown in FIG.
b) Installed.

Both forks 8a and 8b have horizontal portions 8a ₁ ,
It consists of a vertical part 8b ₁ and vertical parts 8a ₂ and 8b ₂ , and a support 12 is fixed by welding to the inside of the bent part.
A freely rotatable pad 14 is set on the support 12 via a bearing 13 (FIG. 3) so as to be freely rotatable about its axis. The free rotation pad 1
4 is formed by fixing a rubber elastic body 14a to the shaft body 14b by adhesive or the like. The end of the shaft body 14b is supported by a ring 15 to prevent it from coming off in the axial direction. The elastic bodies 14a of both freely rotating pads 14 are configured to face each other. The reason why the support 12 and the free rotation pad 14 are installed at the bending part of the fork 8 is to enable so-called fork work in which pallets and cargo are placed on the horizontal parts 8a ₁ and 8b _{1 and} the cargo is moved. It's for a reason.
Further, the support 12 is used to reinforce the bent portion.

In the forklift truck 1 of the present invention configured as described above, when the driver lifts up a package that is lying on its side,
By operating the clamp control mechanism 7, the distance W between the two forks 8a and 8b is changed, and one end of the package 11 is securely clamped on the surface of the pad 14a. In such a state, the freely rotating pad 1
4 can rotate about its axis, so after clamping, the cylinder 9 is activated to raise the fork 8, and then the vehicle body is moved forward a little to erect the package.

In this way, the present invention is a forklift in which the distance between both forks can be changed by operation from the driver's seat. Since rotating pads are installed and the surfaces of the pads are arranged to face each other, conventionally the driver had to adjust the clamping force of the fork when raising a package that was lying on its side. However, in the present invention, the driver operates from the driver's cab to securely hold the package with the fork, and then raises the fork.
This can be accomplished by simply moving the forklift forward a little. Further, in the present invention, since the freely rotating pad is installed on a support provided at the rear end r of the fork, that is, at the bent portion where the horizontal and vertical portions intersect, conventional fork work is possible.
Furthermore, in the present invention, both forks can be reinforced by providing supports at the bent portions of both forks.

In the above description, the work of raising and standing a packaged item has been described, but the work of laying down a packaged item that is standing upside down can also be performed at the same time.

[Brief explanation of the drawing]

FIG. 1 is a side view showing the entire forklift according to the present invention, FIG. 2 is a perspective view showing details of the fork, and FIG. 3 is a sectional view taken along the line -- in FIG. In the figure, code 1 is a forklift, 8a, 8b
is a fork, and 14 is a freely rotating pad.

Claims (1)

[Scope of utility model registration request] In a forklift in which the distance between both forks can be changed by operation from the driver's seat, a support is provided at a bending part from a horizontal part to a vertical part of both forks, and the support is freely rotatable around an axis. A forklift having a fork with a freely rotating pad, characterized in that a rotating pad is installed and the surfaces of the pads are arranged so as to face each other.
