What separates Harrison Hydra-Gen from the competition? Simply put, Harrison hydraulic generators and mobile power solutions have been “PROVEN UNDER PRESSURE”, since 1969. There is no secret to our longevity and success; it is our commitment to quality!  We place emphasis on where it should be; in the components of our products. Our commitment to quality and our testing procedures allow us to remain cost-competitive with lower quality systems by avoiding unnecessary service claims.


Harrison Hydra-Gen, LTD. engages primarily in the manufacturing and sales of hydraulic generators for mobile applications serving the aerial work platform, emergency apparatus, oil field, marine, utility vehicle, government, construction, and agricultural markets.

Harrison Hydra-Gen was a division of Harrison Equipment Company which was founded in 1942 as an electronics components distributor. Schlumberger Well Services approached Harrison in 1969 to develop a hydraulic-driven generator for its use in the oilfield market. Thus, Harrison Hydra -Gen® began the journey into mobile hydraulic power generation.

With over 50 years of experience Harrison Hydra – Gen®, LTD. is reliable hydraulic mobile power.
