Generator Combo Trailer Details

Why haul three industrial trailers to a job site when one will do? This 3-in-1 Combo water, generator, and light tower trailer brings up to 500 gallons of water (all components are rated for potable water), as well as mobile power & light to your project. When full, the mounted diesel engine's 240-gallon diesel tanks can provide more than 300 hours of mobile power and light to any job site accessible by road. Surge lights, breakaway chain and other safety features are included with this DOT compliant trailer.

The 25' Lighting Tower features 4 x 320-watt, long-lasting LED lighting fixtures. This enables your crew to work early mornings or into the evenings. Step, handholds and slip-resistant treads provide easy and safe access to the light tower mast. The drop-leg jack and outrigger jacks on the trailer can be adjusted for maximum stability.
