Designed for the toughest environments giving the most power in minimal space.
Maximum power provided out of a smaller footprint than gas powered options, that can be placed out-of-sight out-of-mind on your apparatus.
No secondary polluting gas engine is required leaving no additional carbon footprint. Also removing the need for an added inverter removing common failure points seen in the field.
Multiple AC voltages available!
What is a Hydraulic Generator?
Simply put. The ability to transfer horsepower from the main chassis engine to the AC generator through hydraulics, creating the AC power needed without a secondary gas engine.
Essentially, the hydraulic pump on the PTO is rotated at a constant speed, transferring the main engine's horsepower to a hydraulic motor attached to the AC generator.
And Eureka! AC Power on the fly!
This provides the flexibility of locating the generator remotely and mounting it in multiple locations.
Out-of-sight and Out-of-mind!
