Design and Optimization Experiment of Steel Channel Composite Beam Crane Structure

I-shaped beam is mainly adopted as the walking girder profile in single beam cranes which are currently used. The girder of the I-shaped beam has many advantages. However, the girder of I-shaped beam also has the following defects in actual use, namely the weight is heavy, external components are conflicted with monorail easily, monorail derailment occurs, etc. A lifting system with built-in crane girder and built-in driving crane as the main structure is designed and studied in order to make up for the defects of I-shaped beam structure. The I-shaped beam track is designed into a steel channel composite ([]-shaped) track. A built-in flat wheel trolley is used for driving in the track instead of me-shaped beam monorail crane. The steel channel composite beam crane undergoes factory loading test and stress-strain analysis in order to better analyse and collect structure optimization data, and its feasibility and practicability are verified by experimental data. The advantages of the steel channel composite beam crane structure are summarized, and the future built-in crane lifting system is prospected finally. (paper)
