Truss Jib - Truss jib's can be used to be able to lift, move and place trusses. The additional part is designed to function as an extended jib additional part together with a triangular or pyramid shaped frame. Normally, truss jibs are mounted on machines like a compact telehandler, a skid steer loader or even a forklift using a quick-coupler attachment.
Older kind cranes that have deep triangular truss jibs are most often assemble and fastened using bolts and rivets into standard open structural shapes. There are rarely any welds on these style jibs. Each and every riveted or bolted joint is susceptible to corrosion and thus requires frequent maintenance and check up.
Truss jibs are built with a back-to-back arrangement of lacing members separated by the width of the flange thickness of another structural member. This design causes narrow separation among the flat surfaces of the lacings. There is little room and limited access to clean and preserve them against rust. Lots of rivets become loose and corrode in their bores and must be replaced.
