Load testing device for railway vehicle bogie frame

摘要

The present invention relates to a load testing apparatus for a railway vehicle bogie frame, wherein the hydraulic oil pressure supplied to the hydraulic cylinder (4) applying the load to the bogie frame (3) is controlled through an electromagnetic proportional control valve (2), The output of the stress gauge 6 provided in the load cell 5 and the bogie frame 3 while the load cell 5 for measuring the magnitude of the load is provided between the hydraulic cylinder 4 and the bogie frame 3. The signal is processed in the data processor 7 so that the correct load and the resulting stress can be measured.
