Introduction

The Power Cube, Version 15.6 is a powerful, portable hydraulic power supply that operates efficiently and with minimal noise. The design combines a 28 HP Briggs & Stratton engine and a fixed-displacement hydraulic pump that has proven to work well with OSE machines and for other compatible hydraulic machines. This version includes a frame of 4" x 4" tubular steel that provides a strong structural frame for mounting other power cubes or attachments.

The Power Cube marks the next level of quick connect modularity, making it easy to assemble, use and maintain and is standard for all hydraulic equipment in the Global Village Construction Set.

NOTE: This document is still under development and is not ready yet for "Prime Time" fabrication. This note will be removed when it has reached a "comfortable" level of completion.

Development

The Power Cube has gone through a series of updates and this page reflects the current designs of Version 7s of the Power Cube.

This design has proven to work well and has had few updates lately. Here are the latest updates:

Oct 2014: Added a pressure relief valve and associated plumbing - TLG.
Oct 2014: Changed sight gauge to shorter model and moved above the suction strainer for greater visibility - TLG.
Apr 2015: Added a pressure gauge - TLG.
May 2015: Moved the filler neck near the center of the tank to prevent fuel leaks due to side-to-side "sloshing".
Jun 2015: Changed fuel filler to use extended neck (from coyote-gear.com) to reduce leaks due to "sloshing":
