Truss boom's could be used to pick up, move and place trusses. The attachment is designed to operate as an extended boom additional part with a pyramid or triangular shaped frame. Typically, truss booms are mounted on equipment like a compact telehandler, a skid steer loader or even a forklift utilizing a quick-coupler attachment.
Older cranes have deep triangular truss booms which are assembled from standard open structural shapes that are fastened with bolts or rivets. On these style booms, there are little if any welds. Each bolted or riveted joint is susceptible to rust and therefore needs frequent upkeep and inspection.
A common design attribute of the truss boom is the back-to-back composition of lacing members. These are separated by the width of the flange thickness of an additional structural member. This design causes narrow separation between the smooth exteriors of the lacings. There is limited access and little room to preserve and clean them against rust. Lots of rivets loosen and corrode inside their bores and must be replaced.
