ABSTRACT:
A lock assembly is provided to secure a multi-stage folding boom assembly having left and right booms, each boom having an middle section that pivots about a vertical axis with respect to an inner section, an outer section that pivots about a second vertical axis with respect to the middle section. The lock assembly includes a first interlock portion that receives a second interlock portion when the first section pivots laterally inward about the first vertical axis with respect to the second section to a first stage folded position. As the middle section pivots forward and laterally inward toward a second stage folded position with respect to the third section, the first interlock portion slidably moves and interlocks with the second interlock portion to restrain the outer section from falling out of alignment with respect to the middle section.
