Abstract: A tooling for longitudinal tension and compression test with one clamping was developed,sothat the static strength test of all large railway maintenance machinery frame can be completed with verti-cal weights, car lifting machines, etc. Static strength tests of various frames have been completed. Thetest standards of static strength of large railway maintenance machinery frame was analyzed and dis-cussed. The author thinks that the current standard used in our country is too strict and is not apply tothe domestic large railway maintenance machinery.

Key words:  large railway maintenance machinery: frame, static strength test, tooling: discussionon standards
