Steel-trailer specialist Kalyn Siebert, a subsidiary of Heil Trailer, positions its entry to the end-dump market as "a lightweight steel end-dump trailer that is more versatile and less expensive than aluminum." The Altralite dump trailer is 38 ft. 6 in. long, with 26.3-cu.-yd. capacity (30.9 cu. yd. with sideboards), and weighs 12,100 lbs.
- 46-degree dumping angle keeps all axles on the ground into the fifth dump stage
- Bathtub design keeps the load’s center of gravity closer to the trailer’s centerline
- Six longitudinal beams add strength
- Tailgate hinge is higher, fully braced, with a forward slant to ensures positive closing
