The equipment is mainly used for the static pressure test and measurement of the Two-axle EMUs train and trailer bogies (including swing bogie, radial bogie and magnetic rail brake bogie) of various railway passenger car. The equipment can efficiently complete the measurement of axle spacing, axle parallelism, wheel inside distance, wheel-rail load, wheel weight difference and height of bogie. We have two types of test benches: 50 tons and 70 tons
