Abstract
A boom assembly is bent at a longitudinal center portion thereof to present an upwardly convex shape. The assembly includes a front boom body and a rear boom body. The front boom body and the rear main body each includes a main body consisting essentially of a pair of right and left lateral plates and a top plate interconnecting upper edges of the respective lateral plates. The main body is formed with an upper face and a lower edge thereof being bent in a longitudinal direction thereof into an arc face having a predetermined radius of curvature. The front or rear main body further includes a bottom plate disposed downwardly of the top plate and between the right and left lateral plates. Each main body is formed by bending a plate member into a reverse U-shaped cross section and each bottom plate is comprised of a plate member provided separately from the plate member forming the main body.
