Introduction
A discussion has taken place concerning modifications to the Power Cube for the upcoming OSEBG LifeTrac build. The question was raised about powering the LifeTrac with a single more powerful Power Cube instead of two current Power Cubes.
Similar Hydraulic Power Units
Foster 35 HP diesel hydraulic power unit @ $18,000 and 3100 lbs (compare to Power Cube @ $2600 and 500 lbs):
The Foster gasoline "Power Packs" are more comparable to the Power Cube - it is larger and heavier, but largely due to the 25 gal hydraulic reservoir:
Options
Engine
- Diesel engines are heavier. For example this 26.4 HP engine weighs 171 lbs dry and without radiator, fan or water. It is comparable in price to some gasoline engines ($2195):
- Kohler engines - up to 38 HP in similar configuration as we use:
- This is the 28 HP B&S engine I've been using - it has an excellent price of < $700. Shipping weight: 100 lbs (in reality: 85 lbs):
- The 36 HP B&S engine adds 28% more power, but costs more than 3x the price. Shipping weight: 135 lbs:
Of course, more power means more fluid flow and heat dissipation. The hydraulic plumbing must also be considered and adjusted if necessary. The pump will have to change as well.
Hydraulic Pump
- The pump currently being used
- This Cessna pump can handle the extra power:
