Abstract

A lift truck in which a hood on which is mounted an operator'"'"'s seat normally covers a compartment housing a vehicle drive component, such as a battery. The hood has an opening registrable with a valve block, the hood being pivotable rearwardly of the truck to expose the drive component, the valve block being pivotable forwardly of the drive component compartment when the hood is open so as to enable the drive component to be elevated from the truck without interference from the hood or valve control. The valve block is pivotably mounted on an angle member which extends over a portion of the drive component when in operative position and which may swing forwardly from a pivot located at the lower end of a vertical leg thereof to an inoperative position when the hood is raised.

Claims

1. In a lift truck having an operator'"'"'s station and a pivoted hood which normally covers a vehicle drive component of the truck such as a battery means and on which is mounted an operator'"'"'s seat, said hood being pivotable rearwardly of the truck to a position in which said drive component is exposed, operator control means for operating one or more lift truck components supported from a position adjacent the front side of said drive component and having at least a portion thereof which normally overlies in a horizontal direction a portion of said drive component, and an opening in said hood registrable with said control means which extends upwardly through said opening for operation by the operator when said control means is in said latter position and the hood is pivoted to its normally down position, said control means being pivotable forwardly on the support thereof to a position outside the projected area of said drive component in a vertical direction when said hood is pivoted rearwardly out of registry with said control means.

2. A lift truck as claimed in claim 1 wherein said drive component is a drive battery in an electric truck, and said control means includes a plurality of hydraulic valve control levers which extend upwardly through the hood when in registry with said hood opening.

3. A lift truck as claimed in claim 1 wherein the mounting for said control means includes an angle member having an operative position in which a downwardly depending leg is mounted pivotably from the lower end portion thereof and having a substantially rearwardly horizontally extending leg on which the control means is mounted, said angle member being pivotable forwardly to an inoperative position in which the control means and horizontally disposed leg are located outside of said projected area of the drive component.

4. A lift truck as claimed in claim 1 wherein said operator control means comprises a hydraulic valve block and upwardly extending control valve levers connected thereto all supported from mounting means, said mounting means including a member extending rearwardly over a portion of said drive component wherein the control means is in operative position and pivotable forwardly of said drive component wherein said control means is in an inoperative position.

5. A lift truck as claimed in claim 4 wherein said mounting means comprises an angle member having a downwardly depending leg supported pivotably from a position below the upper surface of said drive component such that the mounting means with said control means is swingable forwardly out of the said projected area of said drive component when said hood is pivoted rearwardly out of said projected area and out of registry with said control means.

6. A lift truck as claimed in claim 1 wherein said drive component is elevatable out of its compartment in a vertical direction without interference with said hood or control means when the latter are pivoted to said inoperative positions.

7. A lift truck as claimed in claim 4 wherein a hydraulic conduit is connected to the valve block and extends downwardly and forwardly therefrom, the downward extension of said conduit being movable forwardly with said valve block to effect a non-kinking bend radius with the forwardly extending conduit portion.

8. A lift truck as claimed in claim 4 wherein the valve block is located beneath the upper panel cover of the hood and above the upper surface of the drive component, said control levers extending through said hood and above said upper panel.

9. In a sit-down rider type electric lift truck having a generally centrally located drive battery and a hood assembly having an operator'"'"'s seat mounted on the top thereof pivotably connected to the truck at the rear end portion thereof adapted to cover the drive battery in operative position and pivotable rearwardly of the truck to uncover the drive battery in inoperative position, an opening in said hood, hydraulic valve control means for operating hydraulic components of the truck mounted from a position adjacent the front side of said drive battery in such a manner that the valve control means can be pivoted forwardly from a position which extends rearwardly over a portion of said drive battery to a position outside of the projected area of said drive battery in a vertical direction, said valve control means when in a retracted operative position being registrable with said hood opening.

10. A lift truck as claimed in claim 9 wherein said hydraulic control means includes hydraulic valve means and control lever means connected thereto, said valve means being located in normal position intermediate the upper surface of the hood and the upper surface of the drive battery, said lever means extending from said valve means upwardly through said hood opening for manual control by the operator.
