SL3300AR End Dump

The SL3300 is designed to take the most punishing work and provide the biggest payload without extra effort.

The 40 ton capacity hoist with five lift stages makes for faster offloading. Control and stability is provided by a beefy suspension with a 60” axle spread.

Because of the wide track and the HD 22,500 lb. axles, handling heavy loads is safer and more effective. For increased raised box stability the airbag system auto-dumps when the box is raised.

We built the box tough. The outer sides are formed with 12 gauge high tensile steel and the interior is designed with smooth slopes and corners. The floor is a solid one piece 3/16” plate that can handle the toughest loads.
