2024 Rice Trailers 7X18+4 Promax Industrial 21K Equipment Trailer for Sale
The 2024 Rice Trailers 7X18+4 Promax Industrial (model FMHDMH8222) is a heavy-duty flatbed equipment trailer engineered for the toughest hauling jobs. This new, black, 21K industrial equipment trailer combines an 18′ main deck with a 4′ beavertail and full-width fold-up ramps, plus a hydraulic jack, giving contractors and heavy-equipment operators a 21,000 lb GVWR and a massive 16,900 lb payload.
Industrial-Grade Capacity
The 18+4 layout gives you a long, flat carrying surface plus a gentle loading ramp section, so full-width fold-up ramps let you drive machinery on across the entire deck width – ideal for skid steers, tractors, and mid-size excavators. Two 7,000 lb braked axles and a 2-5/16″ 14,000 lb adjustable coupler anchor the load, while the 6″ channel tongue and main frame carry the Promax name for a reason.
Work-Ready Features
The added hydraulic jack takes the muscle out of hitching a heavy trailer, and 5′ spring-assisted fold-up ramps make loading manageable for one person. Pressure-treated wood decking withstands tracked and wheeled equipment, and the complete powder coat finish with fully sealed modular wiring keeps corrosion at bay through years of outdoor use.
