Here is the double-acting version of the 5 gallon, 5.5HP power pack.
Used mainly for running crib jacks, but usable on all kinds of double-acting (power-up AND power-down) jacks, it can be used with dollies equipped with load-bearing jacks, and/or hydraulic steering.
By opening a needle valve to the side of the main control valve, this unit can be used with single-acting jacks.
Note the ease with which on person can move the unit.
See the extra needle valve on the advance (upper) manifold?
This allows very fine control when lowering the load.
