The plans on the OSE website are for version 4, but it is under renovation.
I just completed version 5 (just delivered to OSE for testing) and am about to begin on version 6.
Version 6 will include several updates:
- 28 HP engine
- Larger 7 gallon fuel tank
- Symmetric fuel/hydraulic tanks
- Simplified engine mounting and access to pump & coupling
- Thermostatically controlled oil cooling fan
- Rubber vibration mounts for engine
- Commercial muffler
- Control / hydraulic panel
Here are my best answers to your questions - using Power Cube 6:
- Weight: Approx 150 lbs dry. Hydraulic oil and fuel can add up to 100 lbs (14 gallons @ 7.3 lbs/gallon).
- Dimensions: 27" x 27" x 27" cube
- CG: If you mean "Center of Gravity", no data on this yet, but it will vary with fluid distribution in the tanks
- Duration: No data yet, as we are using a new engine. This also depends on power usage.
- Fuel: 7 Gallons
Notes:
- The power is delivered via hydraulic fluid power through the quick coupler connectors.
- The Power cube attaches to the LifeTrac with the quick attach plates - which are at 45 degrees.
- I would like to add remote controls to the Power Cube via electronic interface, but haven't started on this yet. This will be very important for remote throttle, start & stop.
- I have discussed with Marcin the possibility of working on a "MicroTrac" walk-behind two wheel tractor that would be like a LARGE, powerful tiller. I envision it to employ the Power Cube for power. It could be just a drive train from a car.
- I have also discussed with Marcin the possibility of splitting the Power Cube into two the engine and drive components, where the engine could be detached from the hydraulic pump via a quick connect shaft coupling. The engine could then be connected to something else (like a car?) for direct drive power. This one is still in the concept phase, but seems reasonable. The key component would be the shaft coupling. Its components would have to be re-arranged, as the engine component could not rely on the presence of the hydraulic tank for support.
