ABSTRACT:
A means to maintain the upper wear pads in a multisection telescopic crane boom in contact with the side plates of the circumscribing boom section to reduce the transverse bending moment on the top plate of the boom section, thus reducing the stress thereon, and allowing the use of a thinner top plate so as to provide a lighter and less costly boom structure.
