Structural connectors for dragline boom and mast tubular clusters and methods for repair, reinforcement and life extension of dragline booms and masts
A construction for a boom such as a dragline boom provides a spade plate that connects lacing members to a main chord at a cluster. The spade plate is curved. One edge of the spade plate has tabs attached to the lacing members. Another edge of the spade plate is attached to the main chord. The spade plate may be applied for new construction or repair.
