This Pioneer pivot arm system is an economical tarping solution for multi-axle roll-off trucks and hook hoists transporting containers of the same height.  The hydraulic drive right angle electric gear motor provides steady and quiet rotation of the roller assembly and a fixed gantry.  To cover a load, the hydraulic motor unwinds the tarp and the torsion spring powered arms pull it toward the back.  To uncover a load, the hydraulic motor winds the tarp onto the roller. 
Applications:  Full size hook lift/cable hoist trucks
Container style:  Containers up to 24' long
Standard tarp:  9’ wide expandable heavy duty mesh
