quick-connect sectional boom members for cranes and the like

摘要

A quick-connect system is disclosed for sectional boom members (23,24) for cranes and the like. The sectional boom members (23,24) comprise chords (31,33) for carrying compressive loads, each chord terminating in an end configured to abut against an end of a chord of an adjacent sectional boom member. The quick-connect system comprises at least one easily alignable connector (36,37,38,39) secured to the ends of at least one of the chords, the connector comprising a compressive load bearing surface (58) intersected by the intersection of the vertical and horizontal neutral axes (40,41) of the chord to which the connector is attached. <IMAGE>
