2020 48′ Wilkens Walking Floor Semi-Trailer (20-521)

The 2020 Wilkens Walking Floor Semi-Trailer (Model 20-521) is engineered to deliver standout performance, reliability, and return on investment. Measuring 48′ long, 102″ wide, and 13′ 6″ high, this fixed triple-axle trailer features a front-lift axle and a heavy-duty walking floor—powered by the proven Keith RF II drive unit — for smooth, controlled unloading without tipping. Its sleek black skins and 19″ bullnose give it a modern look, while quilted barn doors and Dura-Brite super-single wheels ensure durability and low maintenance under the toughest conditions.

Inside, operator convenience meets uptime: the rugged Bulitex liner keeps unloading smooth, an Air-Weigh scale system provides on-the-go payload accuracy, and an integrated toolbox with a sample gate simplifies inspections. Safety and visibility are paramount, thanks to an 80-clear-lens lighting package and an industry-leading Shur-Lok reverse-roll tarp system. The full-width catwalk makes daily checks fast and secure.

Whether you haul grains, biomass, or recyclables, the 2020 Wilkens Walking Floor Semi-Trailer delivers unparalleled efficiency and reliability.
