400t Locomotive Automatic Wheel Press With Double Cylinders With Oil Injection System
Hubei Heqiang Machinery is the leading manufacturer of wheel set press machines in China. It offers the most advanced wheel set pressing equipment available in the railway and other relevant industry. The wheelset presses are used to mount and dismount all of the elements on the axle (wheel discs, brake discs, gears and bearings). With both single and double cylinder version available for option and capacity range from 200 to 800 tons. Our vast range of machines can satisfy all customer requirements in both maintenance and mass production applications.
Application scope:
This Automatic Wheel Press Machine is mainly used for the mounting (colding pressing and oiling pressing), dismounting and back pressure testing of locomotive wheelset wheel discs and driven gears of the HXD series locomotive wheelsets. It can generate, record, save and print the pressing curve (Pressure vs displacement, pressure vs time). A rotation device is supplied with the machine to perform wheel back-to-back, axial run-out and radial run-out measurements after the mounting process has been completed.
