Structural Power Cube

Introduction

The Power Cube, if placed into its own structural frame, can become a structural module that can be integrated readily within the LifeTrac Construction Set. The structural frame enables stacking of Power Cubes so their power can be combined.

Status

Prototypes have been developed, but they were larger than expected. A new design has been developed and is being finalized now (July 2014). This design will be used to build two prototypes and parts are already being ordered for this build.

This design has the following features:

• 8 x 8 x 8 Structural frame
• Built-in pressure relief control
• Interconnect port for equalizing hydraulic fluid in reservoirs
• Easy access to tanks for checking/filling fluids

Files

The original Structural Power Cube design used horizontal tanks, but the new "Vertical" design simplifies the design and packages it into a smaller frame.

Kit Cost Breakdown

Note: This breakdown resulted from ordering parts for two kits. Costs include shipping for ordering two of each component - shipping costs will be higher if ordering components for more or fewer kits. Please note that this does not include the cost of engines, mufflers, the structural steel frame or large bolts.

Assembly

The Structural Power Cube is comprised of modules. Each module can be built separately, then combined for the final assembly. The module are detailed below:

Control Panel

The Control Panel Module groups the Power Cube control and inputs / output connections.

Engine

The Engine Module consists of the engine, mounting plate, exhaust system and shaft coupling.

Frame

The Frame Module is made from 4" x 4" tubing for structural mounting. This module also includes the battery box.

Fuel Tank

The Fuel Tank Module has mounting flanges for mounting on the side of the power cube.

Hydraulic Reservoir

The Hydraulic Reservior Module has several holes for transfer of hydraulic fluid, as well as mounting flanges for mounting on the side of the power cube.

Oil Cooler

The Oil Cooler Module consists of a cooling fan, a radiator, connections and protective expanded steel.

Pump

The Pump Module employs a pump plate to provide quick installation / removal of the pump.

Wiring Harness

The Wiring Harness Module provides electrical connections to components in the Power Cube.
