Synchronous Hydraulic Power Units

Synchronous Hydraulic Power Units

Our Hydra-Pac™ Synchronous Hydraulic Power Units provide synchronized control of multiple hydraulic cylinders. They are suitable for operation of all Hydra-Slide Skidding Systems, Turntables, Climbing Jacks and other double-acting jacking applications.

These power units are designed with multiple independent oil circuits. The circuits are not interconnected, providing equal flow to each line regardless of the weight of the load or the pressure in the circuit

This allows the operator to raise or lower virtually any load equally on all points*

*Synchronous control on all points is within 10% of each other regardless of individual circuit pressure.

Going over some operational and safety features of the Hydra-Pac system with the Jack & Slide crew.
An operator using a Hydra-Pac pump 200 feet (70m) underground to slide a Tunnel Boring Machine approximately 300 feet (100m).
Crew operating the 59-8-8D Hydra-Pac pump to slide an offshore buoy off a barge.
Engine options include Diesel, Propane and Electric drive
Custom built to power 4, 6 or 8 double-acting hydraulic cylinders
30-gallon (113 litre) reservoir with 18 gallons (68 litre) useable oil
Master control valve
Manually-operated individual control valves
Pressure gauges and pressure relief valves on each circuit
Loop filtration circuit
Pressure port outlets with counterbalance valves and CR400 female quick couplers
Include a steel safety guard to protect the hydraulic table and valves, lifting lugs, forklift pockets, wheels and a braking handle for easy transportation and safety
Can also be used with single-acting jacks (requires optional flow control valves, not included)

We use ATF (Automatic Transmission Fluid) as our standard, manufacturer recommended hydraulic oil unless otherwise requested. Oil change-outs to AW32, HF103 or Dextron 3 available at additional cost.
