Truss Jib - A truss jib is actually used to carry and place trusses. It is an extended jib attachment which is equipped with a triangular or pyramid shaped frame. Typically, truss jibs are mounted on equipment like for example a compact telehandler, a skid steer loader or a forklift utilizing a quick-coupler attachment.
Older models of cranes have deep triangular truss jibs which are assembled from standard open structural shapes that are fastened using bolts or rivets. On these style jibs, there are few if any welds. Every bolted or riveted joint is susceptible to rusting and thus needs regular maintenance and check up.
Truss jibs are made with a back-to-back arrangement of lacing members separated by the width of the flange thickness of another structural member. This particular design can cause narrow separation between the flat exteriors of the lacings. There is little room and limited access to preserve and clean them against rust. A lot of bolts loosen and corrode within their bores and should be replaced.
