CNC Wheelset Mount and Demount Press With 300 tons Cylinder Force
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 of the Wheelset Press:
This Automatic Wheel Press is mainly used for the mounting, dismounting and back pressure testing of wheel discs 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 provided with the machine to perform wheel back-to-back, axial run-out and radial run-out measurements after the mounting process has been completed.

Machine features of the CNC Wheelset Press:
- The Wheel Mount Press is a horizontal hydraulic wheel press and will be installed in a pit.
- The Wheel press-fitting Machine is able to mount/dismount both wheels on the same axle without turning the axle and in a sequence first the wheel at one side of the axle then the wheel at the other side.
- Double-end cylinder pressing. Only need one positioning without reversal of the axle to proceed both wheel mounting/dismounting.
- The Wheel Assembly Machine is equipped with special patented centring devices at both ends of two ram cylinders for center hole positioning. The centre can insert into the center hole of both ends of the axle for wheelset positioning. During the whole operation process, it can ensure that the axle center line will be completely concentric with the two ram cylinder centerline to make the ram end face fully matched with the axle end face, without damage on axle center hole and preventing axle from upsetting.
- Unique Invention patented cylindrical ram for wheel mounting, with high pressing accuracy.
- The Wheel Press-Mounting Machine is equipped with an electrical axle lifting jack for wheelset pre-assembly and loading/unloading onto/off from the Machine. It will exit from the Machine during the mounting/dismounting operation.
- The wheel press is equipped with a gearbox support to support the gearbox during the whole mounting/dismounting process.
- The Machine can track and control the whole process, detect the pressing condition of the wheelset, and analyze and process it through industrial computer. It can export the pressure vs displacement curve and other results onto the screen and printer.
- The Machine is designed with acoustic-light alarm to ensure the safe and reliable operation.
- Only required one operator to operate the wheel press machine.
