Demco | Tandem Axle Steel Drop Deck Trailer | Model DD40-5 & DD45-5 | Length 40ft To 45ft | GVWR 68,000 lbs | Horsepower 350-400 HP | For Tractor

DESCRIPTION

Demco’s Beaver Tail Drop Deck Trailers are engineered for easy loading and unloading of heavy equipment and vehicles. Available in lengths from 40' to 45', these trailers feature a 5-foot beaver tail ramp extension with twin spring-assist ramps, plus an optional third ramp for increased loading flexibility. The sloped beaver tail allows for smoother transitions on and off the trailer, reducing the risk of damage and enhancing safety for both operators and equipment.

Constructed with a durable frame, including high-grade steel main beams and cross members, the Demco trailers are designed to handle heavy loads with ease. Key features such as 3-leaf SAF Holland spring suspension, Arvin Meritor 22.5K axles with ABS brakes, and midship turn signals enhance stability and road safety. Additional safety elements, including rubber-mounted LED lights and DOT-compliant conspicuity tape, make this trailer a reliable choice for demanding transport needs.
