The American DJ Crank II Mobile Trussing System is the ultimate mobile lighting stand system that makes life on the road much easier. Before the American II Crank-2, you had to push your heavy lights up by hand. This stage light system with truss lets you set up everything at eye level, then easily crank up to 10" high. The rack offers heavy duty tripod stands and American DJ's road-durable steel I-beam trusses that hold up to 140 lbs.
