Title:Latticed Crane Boom Systems--Analytical Procedure
Issuing Committee:Cranes And Lifting Devices Committee
Scope: This SAE Information Report applies to wire rope supported, latticed crane boom systems mounted on mobile construction type cranes for lift crane service. The purpose of this document is to establish criteria for the analytical evaluation of the basic structural competence of wire rope supported latticed crane boom systems. The criteria and procedures specified include the evaluation of elastic stability for the overall boom system and individual members of the system.
