Abstract

PURPOSE:To enhance the working efficiency at the time of battery replacement on the fork lift. CONSTITUTION:The sides of a battery accommodation chamber 1 are bounded by the facade of a counterweight 3 and frame plates 4, 5, and at this counterweight 3, a stopper part 7 protruding from its front face is provided in a position a little innermore than the frame plate 5 situated opposite the battery put-in/takeout side and above the top of the plate 5. When a battery 1a is to be accommodated in the chamber 1, the battery 1a lifted by a hoist is moved sideways along the facade of the counterweight 3 and is sunk in the position when it comes in contact with the stopper part 7. Thereby the battery 1a is restrained about motions in two directions by the facade of counterweight and the stopper part 7 and is accommodated in the accommodation chamber 1 simply and precisely.

The exchange of a is performed. In this battery exchange, the battery hood 26 is opened and the battery 21a is taken in and out from above the battery storage chamber 21, but since the battery 21a is considerably heavy, a hoist crane or the like is used. .. In this case, the head guard 28, which is the ceiling surface of the operator's cab, is formed with a notch 29 that opens to one side so that the lifted battery 21a can be laterally moved to a position above the battery storage chamber 21.

低下させる原因となっていた。By the way, the front surface of the counterweight 23 and the front and side frame plates 2 are provided.
A side portion of the battery storage chamber 21 partitioned by 4 and 25 is formed in a size close to the battery 21a so that the stored battery 21a can be held. Therefore, when the battery 21a is stored in the battery storage chamber 21, the battery 21a lifted by the hoist crane and laterally moved is lowered while being displaced from the battery storage chamber 21. In addition to being unable to be stored in the battery storage chamber 21 due to collision with 24 and 25, the front and side frame plates 2
The inconvenience that 4 and 25 are deformed or damaged occurs. Therefore, since the laterally moving battery 21a must be accurately stopped at a predetermined position above the battery storage chamber 21, it takes a long time to perform the alignment, which causes a significant reduction in work efficiency.

業能率の向上が可能となる。In the battery forklift according to the present invention, when the battery hoisted by a hoist crane or the like is moved laterally along the front surface of the counterweight when the battery is stored in the battery storage chamber, the battery is located at an appropriate position above the battery storage chamber. When it reaches, it contacts the stopper. When the battery is lowered from that state, the battery is accurately stored in the proper position in the battery storage chamber by being restricted in two directions by the front surface of the counterweight and the stopper portion. Therefore, the alignment above the battery storage chamber can be performed extremely easily and accurately, and thereby the work efficiency can be improved.
