HOBART GROUND SYSTEMS Your Total Systems Provider

Hobart Ground Systems combines Hobart Ground Power, Trilectron/Air-A-Plane,

ITW Military GSE and J&B Aviation and their world-renowned engineering,

design, sales, and service teams to provide a total systems solution for the

commercial and military aviation ground support industries. Our user-friendly

designs, superior performance, and proven reliability, provide our customers

the best value in the industry.

Rugged~Compact & Efficient Design:The JetEx®7D operates at 1800 RPM giving a much quieter and more fuel-efficient

power delivery system. The low profile design, combined with our rugged

5th wheel steering, provides superior visibility and maneuverability in today’s

congested ramp areas.

The reduced fuel consumption rate provides fuel cost savings and reduces engine

emissions, which support the “Going Green” initiatives of the GSE industry.

The Hobart GPU features the Cummins “4BT” series electronic

diesel engine and the Hobart designed and manufactured single

bearing generator. A key benefit is that there is parts compatibility

with prior JetEx® Models (4,5 and 6). Integrating customer influenced

design, innovative technology, and Hobart’s years of engineering

expertise maximizes the GPU performance and maintains the

traditional Hobart standard of durability and reliability.

Hobart Ground Systems is your Total Systems

Provider for reliable 28.5 VDC power.
