Abstract

Disclosed is an improved battery operated fork-lift truck having at its rear end a frame structure comprising a plurality of vertically, horizontally or otherwise extending frame and wall members which define a plurality of compartments which are satisfactorily closed themselves and independent of one another to accommodate in a mutually isolated fashion a variety of equipment required for operation of the truck.

Claims

1. A battery operated fork-lift truck comprising:

an end frame member vertically extending from a base support adjacent to the rear end of said truck;

an operator'"'"'s cab provided behind said end frame member and open at said rear end of said truck;

a plurality of compartments defined by said end frame member around said operator'"'"'s cab, said compartments being of individually and mutually substantially closed construction and including a first compartment for hydraulic apparatus, a second compartment for electrical control devices and a third compartment for a driving unit;

a first partition wall extending from said end frame member and defining said first and second compartments in front of said end frame member;

means defining a separate open space below said first and second compartments; and

a second partition wall extending from said end frame member along the height of said operator'"'"'s cab and defining said third compartment adjacent to said operator'"'"'s cab behind said end frame member.

2. The fork-lift truck as defined in claim 1, further including a third partition wall extending from said end frame member along the height of said operator'"'"'s cab and defining a tank for hydraulic fluid behind said end frame member on the opposite side of said operator'"'"'s cab from said third compartment.

3. The fork-lift truck as defined in claim 1, wherein said separate open space is open at its front end and at its opposite lateral ends and defines a battery compartment.

4. The fork-lift truck as defined in claim 3, wherein said first, second and battery compartments are defined in front of said end frame member and said third compartment, said operator'"'"'s cab and a tank for hydraulic fluid are defined behind said end frame member.

5. A battery operated fork-lift truck comprising:

an end frame member vertically extending from a base support adjacent to the rear end of said truck;

an operator'"'"'s cab provided behind said end frame member and open at said rear end of said truck;

a plurality of compartments defined by said end frame member around said operator'"'"'s cab, said compartments being of individually and mutually substantially closed construction and including a first compartment for hydraulic apparatus, a second compartment for electrical control devices and a third compartment for a driving unit;

a pair of parallel side frame members vertically extending from said base support and connected to said end frame member at right angles thereto;

a first partition wall extending from said end frame member cooperating with said side frame members to define said first and second compartments and a battery compartment;

a second partition wall extending from said end frame member; and

a third partition wall extending from said end frame member;

said end and side frame members and said second and third partition walls defining said third compartment, said operator'"'"'s cab and a tank for hydraulic fluid.

6. The fork-lift truck as defined in claim 5, including:

a removable cover for closing said first compartment, said cover having one end fastened to said end frame member and an opposite end fastened to said first partition wall;

a removable cover for closing said second compartment and having one end fastened to said first partition wall and an opposite end fastened to said end frame member; and

a door for closing said third compartment, said door having one edge hinged to one of said side frame members and an opposite edge movable to and away from said second partition wall.

7. The fork-lift truck as defined in claim 5, wherein each of said side frame members is formed with a downwardly facing shoulder in front of said end frame member, said shoulder defining a lateral opening for said battery compartment.
