Safety Evaluation of Portal Crane Based on Stress Test

Because of the long service life and slight corrosion of metal structure of a portal crane in an enterprise, in order to master the technical situation of the main stress components of the portal crane, this paper establishes the three-dimensional model of the main stress components of the equipment in ProE software, and then carries on the finite element analysis with the software, obtains the stress nephogram of the portal crane under rated load, and compares with the field stress test results to form an evaluation conclusion.
