RESEARCH ON CRANE BOOMS WITH LIGHTEST WEIGHT MADE OF HIGH STRENGTH STEEL TUBES

Abstract

Abstract: In order to made the crane booms with the lightest weight, we developed a low-carbon, low-alloy and high strength structural steel tubes with tensile strength greater then 785MPa, researched the welding technology and applied them to offshore crane booms. According to different internal forces along booms, used steel lubes with different wall thickness to different sections and gave calculation of critical forces of this kind of booms. Choosing the lightest weight as optimum object, we studied the optimum design of the booms.

Key words: Crane boom, High strength steel lube, Optimum design, Welding technology
