Based on stringing construction of the conductor in power transmission engineering construction, Shanghai Power Transmission and Transformation Engineering Company designed the double rails propelle type crossing frame, which was used to protect the important crossed objects. Before the crossing frame is utilized, the numerical simulation study and the load test study are carried out. This paper describes the study methods for the numerical simulation study and the load test of the double rails propelle type crossing frame, the testing conditions of the crossing frame are determined through analyzing the basic operation conditions of the crossing frame, and the numerical simulation study of the testing operation conditions of the crossing frame is carried out. Safety and stability of the crossing frame are inspected through comparison between the test result and the simulation result, which greatly ensures safety of the crossing frame during engineering application.
