Referring to FIG. 2, the safety bar device of the forklift includes a lift 5 that lifts up and down while moving up and down, a pair of forks 6 that lift up the load, a safety bar support 7 fixed to the lift 5, And a safety bar (8) mounted on a support (7).

The lift 5 is attached to the mast assembly 4 installed in front of the forklift. As the chain moves up and down by the operation of the hydraulic cylinder installed in the master assembly 4, the lift 5 connected to the chain moves up and down.

The fork 6 is mounted on the lift 5 and can adjust the left and right spacing. The forks 6 are installed on both sides of the lift 5 so as to lift the load. The distance between the forks 6 can be adjusted automatically, and the fork 6 is moved along the guide rails provided on the lift 5.

The safety bar support 7 is fixed to the upper portion of the lift 5. The safety bar support 7 is provided with an insertion portion 72 through which the safety bar 8 can be inserted. The first member 82 of the safety bar 8 is inserted into the insertion portion 72 and slides left and right along the guide rail.

The safety bar 8 is adjusted such that the distance between the safety bars 8 on both sides is adjusted by the left and right slides of the first member 82 and the front and rear slides of the second member 84 to the fourth member 88, (8) is adjusted. The left and right slide movement and the back and forth slide movement of the safety bar 8 can be performed manually or automatically.

After the load is loaded on the pair of forks 6 in two stages, the operator moves the first member 82 to the left and right in accordance with the width of the load, and moves the second member 84 to the fourth member Thereby moving the safety bar 8 back and forth so that the safety bar 8 can closely fix the load.

If the cargo is loaded and carried in more than one tier, the view of the driver of the forklift may be obscured by the tier 2 cargo. In the embodiment of the present invention, a camera 93 for front confirmation can be installed on the safety bar 8 in order to secure the field of view of the driver in carrying the two-stage cargo.

It is preferable to install the camera on the safety bar 8 because the lift 5 and the safety bar support 7 are covered by the two-stage load when the fork is loaded on the fork 6 in two or more stages.

However, if the camera is installed on the first member 82 to the fourth member 88 of the safety bar 8, the camera must be installed upright in the forward direction.

When the camera is installed in the left and right longitudinal direction in the first member 82, the camera must be inserted into the insertion portion 72, so that the camera can be installed in the longitudinal direction of the longitudinal direction rather than in the longitudinal direction. In addition, when the camera is installed in the second member 84 to the fourth member 88, the camera must be inserted into the member, so that a space for inserting the camera must be provided inside the member.

In order not to create a camera inserting space inside the member, a camera 93 may be provided on the fixing member 90 as shown. Since the fixing member 90 is placed in front of the load, the camera 93 can be installed easily and the front view can be efficiently photographed by providing the camera 93 on the fixing member 90. The cable 95 of the camera 93 is extended and retracted along the longitudinal direction of the second member 84 to the third member 86 as shown in FIG. Respectively. That is, the cable 95 of the camera 93 is spiral so as to be elastic so that the second member 84 to the fourth member 88 can be stretched and contracted together with the back and forth slide movement.

The camera 93 is capable of viewing the forward direction through the image output through the camera even if the cargo is loaded on the fork 6 with high load.
