Combo Trailer Details
Why get just a Water Trailer when you also can have a Mobile Light Tower and Power Trailer, all in one fully-assembled, road-ready unit? This efficient, 3-in-1 Combo Trailer can bring up to 500 gallons of water to your worksite, with all water system components rated potable. The optional Freeze Protection Package extends use to multiple seasons in colder climates.
The Combo Trailer helps you get the job done on time and on-budget, and on any worksite accessible by truck.
The 240-gallon diesel reservoir, when filled, powers the 22.3 hp Caterpillar engine inside the 15kW Allmand generator. The resulting 300+ hours of electricity and light for your project site mean less down time; more progress. A variety of electrical outlets – ranging from 20 AMP /120V to 50 AMP / 240 V – give you and your crew the mobile power to get the job done right in as little time as possible.
The 26'8" Mobile Light Tower is hydraulically actuated, making for smooth extension and retraction of its six sections. A drop-leg jack and outriggers stabilize the tower. Equivalent to having a separate light tower trailer on site, the well-designed mobile light tower has handholds and a step with slip-resistant treads. These safety features allow for easy access to the light tower mast and its four 320-watt LED fixtures.
