Description

Side shift carriage for forklift

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to side shift carriages for forklifts, and more particularly to side shift carriages for forklifts that are designed to increase the cargo lifting capacity of the forklifts.

Generally, the main body carriage is provided in front of the main body of the forklift, and the side shift carriage is provided on the main body carriage. The side shift carriage is conveniently used as needed when the forklift lifts the cargo, moves it and then unloads it to the required position. For example, a forklift may need to move an object lifted by its fork to the required position and then move the forklift itself to the left or right in order to lower the load as generally accurate. In this case, the driver repeatedly moves the forklift to reverse, forward, right turn and left turn to move the position of the forklift to the required unloading point. This series of operations adds to operator fatigue and consumes time and fuel. Side shift carriage is used to solve this problem. That is, this problem is solved by the side shift carriage being moved left and right by the cylinder on the main carriage.

1 and 2 show a state in which the forklift side shift carriage 12 according to the prior art is mounted on the main carriage 10. A separate upper guide 18 is attached to the upper end 14 of the connecting member 22 of the side shift carriage 12. Similarly, a separate lower guide 20 is attached to the lower end 16 of the connecting member 22. The upper guide 18 and the lower guide 20 are slidably coupled to the upper rail 11 and the lower rail 13 of the body carriage 10, respectively. The rod 31 of the cylinder 30 attached to the main carriage 10 is connected to the connecting member 22. Accordingly, as the cylinder 30 operates, the side shift carriage 12 can move laterally.

However, as shown in FIG. 2, the sliding center of the upper rail 11 and the lower rail 13 and the upper guide 18 and the lower guide 20 and the center of the rod 31 of the cylinder 30 Since the distance as much as C, there is a problem that the lifting capacity is lowered when the side shift carriage moves left and right.

Accordingly, an object of the present invention is to provide a side shift carriage for a forklift that is designed to solve the problems described above and to increase the cargo lifting capacity of the side shift carriage.

Side shift carriage for forklift according to a preferred embodiment of the present invention for achieving the above object is mounted to the left and right by a cylinder mounted on the main carriage on the upper rail and the lower rail of the main carriage provided in the front of the main body of the forklift. A side shift carriage for a forklift, comprising: an upper guide slidably coupled to the upper rail, a lower guide slidably coupled to the lower rail, and a connection member for connecting the upper guide and the lower guide. And a cylinder end formed with both rods extending from the lower side of the upper guide such that the sliding center of the upper rail and the lower rail, the upper guide, and the lower guide is substantially coincident with the center of the rod of both ends of the cylinder. Opened on a fixed bracket It is characterized in that is.

The features of the present invention can be better understood from the detailed description with reference to the accompanying drawings.

3 and 4 show a state in which the forklift side shift carriage 12 is mounted to the main carriage 10 according to a preferred embodiment of the present invention. The upper guide 18 is directly connected to the upper end of the connecting member 22. The upper guide 18 is slidably coupled to the upper rail 11. Similarly, the lower guide 20 is directly connected to the lower end of the connecting member 22. The lower guide 20 is slidably coupled to the lower rail 13.

As shown in Figs. 3 and 5, the cylinder 30 is provided with a mounting flange 30a. The mounting flange 30a is fastened to the cylinder fixing bracket 13 provided in the main carriage 10. On the other hand, the lower end of the upper guide 18 is provided with a cylinder end fixing bracket 18a. The rod 31 of the cylinder 30 is connected to this cylinder end fixed bracket 18a, respectively. A fixing hole 18b is formed in the cylinder end fixing bracket 18a. The cylinder rod 31 is fixed by the fixing pin 41 and the fixing split pin 43 through the fixing hole 18b. As shown in Figs. 4 and 5, the cylinder end fixing bracket 18a has a sliding center C 'between the upper rail 11 and the lower rail 13 and the upper guide 18 and the lower guide 20. It extends below the upper guide 18 so as to substantially coincide with the center of the rod 31 at both ends of the cylinder 30.

On the other hand, a bushing 40 is provided between the upper rail and the upper guide and between the lower rail and the lower guide, respectively. This bushing 40 is fastened to the upper rail 11 and the lower rail 13 by the bushing fixing screw 42 as shown in FIG. Accordingly, the sliding motion of the upper rail 11 and the upper guide 18 and the sliding motion of the lower rail 13 and the lower guide 20 are smoothed.

As the hydraulic oil flows into and out of the first port 37 and the second port 39 of the cylinder 30, the side shift carriage 12 moves at a lateral distance S. At this time, as mentioned above, the sliding center C 'between the upper rail 11 and the lower rail 13 and the upper guide 18 and the lower guide 20 is formed at both ends of the rod 31 of the cylinder 30. Since it is generally coincident with the center, it is possible to increase the lifting capacity of the side shift carriage 12.

As described above, the side shift carriage according to a preferred embodiment of the present invention has a simple configuration, the number of parts is reduced, and the effect of increasing the lifting capacity of the cargo. In addition, there is an advantage that the bushing is provided between each rail and the guide can be more smooth sliding movement.
