Safety Analysis of Landing-Type Lifting Pole with Double-Level Arms under Wind Load Function

摘要

According to design requirements for landing-type lifting pole with double-level arms, the working conditions of landing-type lifting pole with double-level arms are proposed under different wind pressures and wind directions, and the component stresses of several important standard sections of pole body are calculated under different load factors. For standard sections whose main chord members cannot meet strength and safety requirements, this thesis considered adding hawser cables, thus obtaining the stress results meeting design requirements. Relevant calculation methods can be taken as reference for lifting pole design.
