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; and a removable battery electrically coupled to both the motor and the powered lift assembly.

2 . The material transport cart of claim 1 , further comprising
a handle coupled to the cart body; cart movement user controls disposed on the handle; and horizontal slide user controls disposed on the body, the horizontal slide user controls spaced apart from the cart movement user controls in a height direction.

3 . 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.

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

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

6 . The material transport cart of claim 5 , 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.

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

8 . The material transport cart of claim 6 , wherein the material containment barrier is recessed relative to the material support surface in the storage position.

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

10 . The material transport cart of claim 6 , wherein the material containment barrier is pivotably connected to the material support body.

11 . A material transport cart comprising:
a cart body; a wheel coupled to the cart body; a motor operable to drive the wheel; a powered lift assembly coupled to the cart body, the powered lift assembly including an attachment receiving portion translatable relative to the cart body; an attachment removably connected to the attachment receiving portion of the powered lift assembly; and a removable battery electrically coupled to both the motor and the powered lift assembly.

12 . The material transport cart of claim 11 , wherein the powered lift assembly includes a hydraulically operated powered lift assembly having an electrically powered hydraulic pump and a hydraulic lift cylinder.

13 . The material transport cart of claim 11 , wherein the attachment includes a tine.

14 . The material transport cart of claim 11 , further comprising a width adjustment assembly to widen or narrow a wheelbase of the cart.

15 . The material transport cart of claim 14 , wherein the width adjustment assembly includes a motor or a hydraulic actuator.

16 . The material transport cart of claim 11 , wherein the powered lift assembly further includes a lifting arm coupled to the attachment receiving portion, the lifting arm configured to translate into and out of the cart body.

17 . The material transport cart of claim 11 , further comprising a pivotable handle with at least one degree of freedom.

18 . The material transport cart of claim 11 , wherein the removable battery is coupled to the cart body in a position between the pivotable handle and the lifting arm.

19 . A material transport cart comprising:
a cart body; a first tine extending from the cart body; a second tine extending from the cart body and spaced apart from the first tine to define an intermediate space between the first tine and the second tine; a bed assembly disposable between the first tine and the second tine, the bed assembly adjustable between a collapsed mode, in which the bed assembly has a reduced size, and an expanded mode, in which the bed assembly occupies a majority of the intermediate space; a removable battery coupled to the cart body.

20 . The material transport cart of claim 19 , wherein the bed assembly is in a folded configuration in the collapsed mode and unfolds to the expanded mode.
