Abstract

A forklift truck, in particular an electric reach truck, having an operator'"'"'s compartment with a battery compartment located to the side of the operator. An operator'"'"'s console is pivotally mounted above the battery compartment so as to be movable into a position where access to the battery can be obtained for servicing or exchange of the battery.

Claims

1. An electric forklift truck comprising:

an operator compartment;

a battery compartment adjacent to said operator compartment;

an operator console, said console housing non-hydraulic, electrical controls for producing an electrical position signal and for actuating hydraulics of said truck, said console being pivotally mounted above said battery compartment and moveable between a closed position overlying said battery compartment and an open position in which access for removal or servicing of said battery is possible; and

a switch for automatically disconnecting battery power to the electrical controls in the console in response to said console being moved to said open position.

2. The truck of claim 1 wherein said console is mounted on a wall of said truck.

3. The truck of claim 1 wherein said battery is connected to said console by a cable, and said disconnecting means is a switch located between said console and said cable.

4. The truck of claim 2 wherein said battery is connected to said console by a cable.

5. The truck of claim 4 wherein said switch is located between said cable and said electrical components in said console.

6. The truck of claim 5 wherein said switch includes an actuating member for operating said switch.

7. An electric forklift truck comprising:

an operator compartment;

a battery compartment adjacent to said operator compartment;

an operator console, housing electrical components for actuating hydraulics of said truck, said console being pivotally mounted above said battery compartment and moveable between a closed position overlying said battery compartment and an open position in which access for removal or servicing of said battery is possible;

said battery being connected to said console by a cable; and

a switch operated by an actuating member and being located between said cable and said electrical component in said console for automatically disconnecting battery power in response to said console being moved to said open position;

wherein said actuating member is positioned to contact a rear wall of said battery compartment when said console is in said closed position to allow current to flow from said battery to said console.

8. The truck of claim 7 wherein said electrical components include means for producing electrical position signals to control the working hydraulics of the truck.

9. The truck of claim 8 wherein said console includes means for processing said position signals before applying said signals to said working hydraulics in order to reduce shock.

10. The truck of claim 9 wherein said producing means is at least one joystick located on said console for operating said working hydraulics.

11. The truck of claim 10 wherein said signals are output from said console through a cable which passes over said console mounting and to a proportional valve located under a seat in said operator compartment to control said working hydraulics such that hydraulic fluid from said working hydraulics is separated from said electrical components.

12. An electric forklift truck comprising:

an operator compartment;

a battery compartment adjacent to said operator compartment, said compartment including a battery; and

a console housing electrical components for actuating working hydraulics on said truck, said console being pivotally mounted to a wall of said truck above said battery compartment and moveable between a closed position overlying said battery compartment and an open position in which access for removal or servicing of said battery is possible, said console including a plurality of joysticks for producing electrical signals for operating said working hydraulics, a cable for connecting said battery to said components, and a switch for disconnecting power from said battery to said console, said switch including an actuating member which contacts a rear wall of said battery compartment when said console is moved to said closed position to allow current to flow from said battery to said console.
