In such a conventional method of mounting a lamp, the lamp protrudes to the driver's seat side, hindering the cargo handling work performed in the driver's seat, thereby deteriorating the workability, and this type of picking. There is a problem in that the driver's seat of a type forklift is narrow and the effective space is reduced due to a protruding ramp. On the other hand, if the effective space is not hindered, the installation location of the lighting equipment such as lamps is limited, and the light becomes oblique and the light enters the eyes and is dazzling. However, there is a problem in that, when the operator places a document, the operator tries to view a document such as a slip and the shadow is formed, making it difficult to see the document. These problems are particularly remarkable in a lift type forklift.

[0004] The present invention has been made in view of the above points, and it is possible to install a lighting apparatus without impairing the effective space of a driver's seat, and to shine light directly from above an operator so as to shine light from above the operator. It is intended to provide a forklift intended to prevent entry.

[0005]

Therefore, in a forklift according to a first aspect of the present invention, in a forklift having a head guard above a driver's seat, a lighting device is arranged in a space of the head guard. It is characterized by.

With this configuration, the lighting equipment can be arranged without impairing the effective space of the driver's seat, and the lighting equipment does not protrude from the head guard. Therefore, the operability of the cargo handling work can be improved without the operator or the load hitting the lighting equipment. In addition, by illuminating light from above the operator with such a lighting device, light does not directly enter the eyes of the operator, and at the same time, the area around the driver's seat is brightened, and the efficiency of cargo handling work can be improved.

[0007] The forklift according to the second aspect is characterized in that the lighting equipment is disposed above an operation unit operated and operated by an operator.

As a result, no shadow can be formed on the upper surface of the operation unit, and when work such as a slip is placed on the upper surface of the operation unit, no shadow can be formed on the upper surface of the operation unit. be able to.

In the forklift according to the third aspect, the lighting fixture is a straight tube fluorescent lamp.

Thus, even a large fluorescent lamp can be arranged without impairing the effective space of the driver's seat.
