Abstract

A modular design for a pressure washer system comprises a support frame including a top mounting surface, a first power assembly configured to be mounted to the support frame, and a cage assembly including a cage frame and a cage attached to the cage frame and configured to extend upwardly from the cage frame at least partially surrounding the power assembly, wherein the cage frame is configured to be attached to the support frame.

Claims (21)

1. A modular design for a pressure washer system comprising:

a support frame including a top mounting surface wherein the support frame comprises a pair of oppositely disposed lateral members defining a length of the support frame, a first cross member coupled between opposing front ends of the pair of longitudinal members, and a second cross member coupled between opposing back ends of the pair of longitudinal members, the first cross member being disposed oppositely from the second cross member, the pair of lateral members and first and second cross members being in planar alignment and forming a rectangular frame;

a first power assembly configured to be mounted to the support frame, wherein the first power assembly includes a PEG unit including a pump, an engine, and a generator;

the PEG unit further comprising a bottom attachment platform, and a pair of mounting ears on either side of the bottom attachment platform configured to attach the first power assembly to the top mounting surface of the support frame,

wherein the pump is mounted on top of the bottom attachment platform,

wherein the pair of mounting ears are spaced laterally away from the pump, the mounting ears also being disposed vertically in a plane above the bottom attachment platform and the pump, wherein the mounting ears are configured to allow the pump to extend at least partially downwardly past the top mounting surface of the support frame,

wherein the engine of the PEG unit is operatively coupled to the bottom attachment platform and spaced vertically in a plane above the mounting ears and is further spaced laterally away from the pump; and

a cage assembly including a cage frame and a cage attached to the cage frame and configured to extend upwardly from the cage frame and at least partially surround the first power assembly,

wherein the cage frame is configured to be attached to the support frame,

wherein the cage frame is in planar alignment with the support frame,

wherein the first power assembly is replaceable with an alternately configured power assembly,

wherein the cage assembly is replaceable by an alternately configured cage assembly, and

wherein the support frame is configured to assemble with alternate configurations of a blower and heat exchange assembly, and/or a tank assembly.

2. The modular design for a pressure washer system of claim 1 , wherein the generator of the PEG unit is operatively coupled to the bottom attachment platform and spaced vertically in a plane above the mounting ears.

3. The modular design for a pressure washer system of claim 1 , wherein the cage assembly further includes a battery attached to the cage frame and at least one fuel tank attached to the cage frame.

4. The modular design for a pressure washer system of claim 1 , further comprising a first blower and heat exchanger assembly configured to be attached to the support frame.

5. The modular design for a pressure washer system of claim 1 , further comprising a first tank assembly including a first cleaning fluid supply tank, a first tank cage frame, and a first tank cage attached to the first tank cage frame and extending upwardly therefrom, at least partially surrounding the first cleaning fluid supply tank.

6. The modular design for a pressure washer system of claim 5 , further comprising at least one chemical tank attached to the first tank cage frame.

7. The modular design for a pressure washer system of claim 5 , further comprising a second tank assembly including a second cleaning fluid supply tank that is differently configured than the first cleaning fluid supply tank.

8. The modular design for a pressure washer system of claim 7 , wherein the support frame is a trailer frame and the first tank assembly and the second tank assembly are attached to the trailer frame side by side.

9. The modular design for a pressure washer system of claim 1 , wherein the support frame is a skid frame.
