The Huck Model 913H POWERIG is a portable, gasoline-powered hydraulic power source designed to operate all Huck Hydraulic Installation Equipment.
Figure 1 shows the construction features of the gas hydraulic power unit and identifies the main components.
Hydraulic pressure is developed by a two-stage, gear piston hydraulic pump driven by a Honda 5.5hp Engine. The pump output is directed to either PULL or RETURN pressure ports of the installation tool by a four-way directional valve. The Directional valve is controlled, with a trigger/switch, from the tool. This is a 12 - volt control system.
Internal relief valves are pre-set at the factory for the protection of operators and equipment. External relief valves control PULL Pressure. and RETURN Pressure. As shipped from the
factory, an external relief valve is set at 5400-5700 psi (37200-39300 kPa) and the return pressure valve is set at 2700-3300 psi (15200-16500 kPa). Pressures are adjustable to match the Huck installation tool being used. See the applicable installation tool manual.
Hydraulic fluid is stored in a reservoir that serves as the base for the motor-pump, and
directional valve. Hydraulic quick disconnect couplers are furnished for connecting hoses to
the installation tool and POWERIG Hydraulic Unit.
This Huck POWERIG Hydraulic Unit includes a roll cage for protection, as well as to facilitate
moving the unit to various work stations. The unit weighs approximately 175 pounds (78.7 kg) when filled with hydraulic fluid
