In addition, the purpose is to enable efficient and safe cargo handling work even in a dark place. [Structure] An inclinometer 4 is attached to a forklift mast 2 at a height easy for a driver to see by a bracket 5, and wiring for illumination is installed.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a forklift used for cargo handling in all industries.

[0002]

[Prior art]

 Conventional forklift trucks were not equipped with an inclinometer for determining the inclination of the vehicle body and the inclination of the mast and fork in the front, rear, left, and right directions during loading, unloading, or while driving. . Since the vehicle body and the inclination of the mast and the fork were visually inspected only by the driver to carry out the work, it was not only extremely dangerous to carry heavy objects and odd-shaped objects, but also efficient. Was extremely bad. Also, at night or in a dark place, it is difficult to determine the inclination.

[0003]

[Problems to be solved by the device]

 As described in the prior art, in order to carry out cargo handling work efficiently and safely, it is necessary to know how much the vehicle body and mast and fork are inclined. Therefore, it is sufficient to attach an inclinometer that can know the inclination of the front, rear, left and right. The inclinometer should be installed in the most reliable place of the forklift, using various scale inclinometers currently in use and transmitted illumination type inclinometers. The present invention utilizes a transillumination type inclinometer that illuminates when the switch is turned on so that the scale can be read even at night or in dark places.

[0004]

[Means for Solving the Problems]

 The current forklift truck has a power source built into the vehicle body (1), and is provided with meters, driving handles, and levers for driving each device, etc., to drive the forklift truck and to lower the front of the vehicle body. There are a mast (2) that can be tilted back and forth with a hydraulic cylinder with the pin at the fulcrum as a fulcrum, and a fork (3) that is movable up and down in parallel with the mast (2) via a roller chain from the hydraulic cylinder. It is composed of Therefore, as shown in FIGS. 1 and 2, by installing the inclinometer (4) at a height position where the driver can easily see the center of the mast (2), the vehicle body (1) and the mast (2) can be separated from each other. The inclination of the fork (3) to the front, back, left and right can always be determined.

[0005]

[Action]

 The drawings from FIG. 3 to FIG. 8 show the configuration of the scale of the inclinometer, and are illustrated so that the front and rear and left and right inclination states of the vehicle body (1) and the mast (2) and the fork (3) can be explained. . The outer scale plate (6) is fixed to the body of the inclinometer, and an angle of 40 degrees indicating the left and right inclinations of the vehicle body (1) and the mast (2) and the fork (3) is centered on the zero point on both sides. Are written above and below. The sphere scale plate (7) is a sphere that is always kept horizontal and has a long hole in the center for moving the pointer (8). The numerical value of 40 degrees is indicated above and below, and the pointer (8) is a pointer that indicates the numerical value by moving according to the change in the front-back movement. FIG. 3 shows that all the mechanisms are horizontal, and FIG. 4 shows that the vehicle body (1) is tilted to the left, that is, both the mast (2) and the fork (3) are moved to the left. It means that I leaned. FIG. 5 shows that the vehicle body (1) leans to the right, and the mast (2) and the fork (3) also lean to the right. FIG. 6 shows that only the vehicle body (1) is tilted backwards, the mast (2) and the forks (3) are tilted backwards, and all the tilts are tilted backwards. FIG. 8 shows that all of them lean to the left, and at the same time, the mast (2) and the fork (3) are tilted backward and the vehicle body (1) is tilted backward. FIG. 6 is a diagram showing that all of them are tilted rearward.

[0006]

【Example】

 As shown in FIG. 1 and FIG. 2, using the bracket (5), the vehicle body (1) is horizontal and the mast (2) is vertical at a height position that is easy for the driver to see in the center of the mast (2). In this condition, install the inclinometer (4) so that it shows that it is horizontal. The inclinometer of the luminous paint scale is attached by the bracket (5) as it is, but in the case of the transillumination type inclinometer (4) used in the present invention, the power source from the battery is used. Wire the switches and attach it with the bracket (5). The inclinometer (4) has various inclinometers currently in use, but any inclinometer may be used.

[0007]

[Effect of device]

 Industrial forklifts use heavy and odd-shaped objects everywhere, so some workplaces are quite ill-conditioned. However, since the inclinometer was not provided, the work was dangerous and inefficient, but by installing the inclinometer of the present invention, the above-mentioned drawbacks were solved and efficient and safe work was performed. I was able to do it.
