Abstract

A material transport cart includes a cart body, a material support body coupled to the cart body, a wheel coupled to the cart body, a motor operable to drive the wheel, and a powered lift assembly. The powered lift assembly is coupled to the cart body and to the material support body. The powered lift assembly is operable to lift the material support body relative to the cart body. A removable battery is electrically coupled to and operable to supply power to both the motor and the powered lift assembly.

First claim

What is claimed is:

1. A material transport cart comprising:
a cart body;
a material support body coupled to the cart body;
a wheel coupled to the material support body;
a motor operable to drive the wheel;
a powered lift assembly coupled to the cart body, the powered lift assembly including a base member configured to engage a ground surface, the powered lift assembly operable to lift the cart body relative to the base member;
a removable battery electrically coupled to both the motor and the powered lift assembly; and
a handle coupled to the cart body;
cart movement user controls disposed on the handle;
horizontal slide user controls disposed on the cart body, the horizontal slide user controls spaced apart from the cart movement user controls in a height direction, the horizontal slide user controls operable to move the material support body relative to the cart body.

2. The material transport cart of claim 1 , wherein the powered lift assembly includes a hydraulically-operated powered lift assembly having an electrically-powered hydraulic pump and a hydraulic lift cylinder.

3. The material transport cart of claim 1 , wherein the material support body is translatably coupled to the cart body.

4. The material transport cart of claim 3 , further comprising at least one material containment barrier connected to the material support body.

5. The material transport cart of claim 4 , wherein
the material support body includes a material support surface; and
the material containment barrier is adjustable between a storage position, in which the material containment barrier does not extend beyond the material support surface, and a containment position, in which the material containment barrier extends beyond the material support surface.

6. The material transport cart of claim 5 , wherein the material containment barrier is substantially flush with the material support surface in the storage position.

7. The material transport cart of claim 5 , wherein the material containment barrier is recessed relative to the material support surface in the storage position.

8. The material transport cart of claim 7 , wherein the material support body defines a recess receiving the material containment barrier in the storage position.

9. The material transport cart of claim 5 , wherein the material containment barrier is pivotably connected to the material support body.
