Abstract

The present disclosure relates generally to lift vehicles that include a carriage having at least three wheels, a lift and a load carrying frame. The load carrying frame is connected to the lift, which is connected to the carriage. A selectively deployable platform is disclosed that is pivotably connected to the carriage and movable between a stowed position and a support position. At least two rollers may be spaced apart and configured to engage and slidably support a battery above the carriage.

Claims

1. A personnel lift vehicle comprising:

a carriage further comprising a front portion and a rear portion;

at least three wheels rotatably connected to the carriage;

a drive motor coupled to at least one of the at least three wheels and being located at the front portion of the carriage;

a telescoping lift connected to and located at the rear portion of the carriage;

a load carrying frame connected to and extending forward from the telescoping lift, and being vertically movable upon operation of the telescoping lift;

the load carrying frame further comprising a bottom portion that provides an operator platform that is disposed forward of the telescoping lift and at a central portion of the carriage between the front and rear portions;

an upstanding member fixedly connected to the carriage and in a fixed position parallel to and horizontally spaced apart from and rearward of the telescoping lift; and

a selectively deployable cargo platform pivotably connected to the upstanding member and spaced apart from the telescoping lift and the load carrying frame, and being movable between a generally vertical stowed position and a substantially horizontal support position wherein when in the substantially horizontal support position the cargo platform further extends outward from an outer perimeter of the carriage and is located at a height spaced above the carriage and the at least three wheels.

2. The personnel lift vehicle according to claim 1, wherein the cargo platform further comprises a pair of sides that are spaced apart and parallel.

3. The lift vehicle according to claim 2, wherein each of the sides includes a slot formed therein.

4. The personnel lift vehicle according to claim 3, wherein each slot in each of the sides of the cargo platform includes an elongated slot portion and a slot portion that is shorter than and substantially perpendicular to the elongated slot portion.

5. The personnel lift vehicle according to claim 4, wherein the carriage further comprises a pair of projections wherein each projection extends through a respective slot in a side of the cargo platform.

6. The personnel lift vehicle according to claim 5, wherein each projection is disposed in the elongated slot portion of a respective slot when the cargo platform is in the stowed position.

7. The personnel lift vehicle according to claim 5, wherein each projection is disposed in the shorter slot portion of a respective slot when the cargo platform is in the support position.

8. The personnel lift vehicle according to claim 5, wherein the pair of projections are connected to the upstanding member that is connected to the carriage.

9. The personnel lift vehicle according to claim 8, wherein a lower surface of the cargo platform engages an upper surface of the upstanding member when the cargo platform is in the support position.

10. The personnel lift vehicle according to claim 1, wherein the cargo platform further comprises a plurality of longitudinal braces and a plurality of lateral braces.

11. The personnel lift vehicle according to claim 1, wherein the cargo platform is disposed within the outer perimeter of the carriage when the cargo platform is in the stowed position.

12. The personnel lift vehicle according to claim 1, wherein the carriage further comprises a catch that engages the cargo platform when the cargo platform is moved to the stowed position.

13. The personnel lift vehicle according to claim 12, wherein the catch further comprises a guide bracket that includes an arm that biases the cargo platform into a secure position when the cargo platform is moved to the stowed position.
