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):Product Web Page
Kohler engines - up to 38 HP in similar configuration as we use:Product Web Page
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):Product Web Page
The 36 HP B&S engine adds 28% more power, but costs more than 3x the price. Shipping weight: 135 lbs:Product Web Page
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.
