The Influence of the Deformability of the Tricycle Portal on the Construction of the Cargo Characteristics of a Jib Rail Crane of the SKR Type
Abstract: The article analyzes the stress-strain state of the three-support portal of the jib rail crane SKR-3500 EM using the SCAD Office software package. The accuracy of positioning the load at the installation site is influenced by the malleability of the design of heavy jib cranes of the SKR type, which are characterized by a large service area. In particular, the malleability of its undercarriage, made in the form of a tricycle portal on a rail-wheeled course, contributes to the overall deformability of the SKR-3500 EM crane. As a result, the tower boom equipment is tilted towards the load being lifted and there is an outflow beyond the load characteristics of the crane, especially when lifting the maximum load. The article evaluates the influence of the malleability of a tricycle portal on the occurrence of boom departure increments and develops recommendations for strengthening the metal structure of the portal in order to reduce its deformability.
Keywords: departure, cargo characteristics, deformability, stress-strain state, portal, increment, boom crane rail.
