ABSTRACT:
A crane, and a boom assembly for a crane, include an outermost boom portion having the area between its front chord members being substantially open. Inner lacing members extend in intersecting pairs between diagonally opposing pairs of chord members for strengthening the boom. The various lacing members in the latticework construction for a crane are connected to the chord members using reusable clevis pin assemblies of a predetermined tolerance. This enables it to be easily assembled and to be readily disassembled for ease of transport and storage in a compact state. It also produces a rigid structure having substantially no internal residual stress.
