The equipment is suitable for measuring the clearance of gearbox bearings during the new manufacturing of railway vehicle wheelsets. It is computer-controlled with human-machine interaction, allowing input of wheelset identification codes, test results, operation information, and data storage and upload. After the test, the gearbox clearance result is automatically recorded. The test method (single test / average of multiple tests) can be set according to customer requirements, and test records are generated and stored.
