Crown's Mono-Mast features a boxed-in design with heavy gauge steel and wide outer C-channels and inner I-beams tied together with massive cross members to minimize twisting and swaying.
The TSP 6000 is available in three different MonoMast styles. The TN mast is the standard mast and provides no main-hoist free lift. Optional masts include the TF, which allows free lift, and the triple stage mast (TT) which greatly reduces the overall collapsed height of the truck.
