350 Tons Railway Horizontal Wheelset Press Oil Injection Mounting
Double cylinder Automatic Wheelset Mounting and Dismounting Press CNC Controlled
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 fully automatic double cylinder wheelset press machine is mainly used for the mounting (colding pressing and oiling pressing), dismounting and back pressure testing of the locomotive wheelsets. It can generate, record, save and print the pressing curve (Pressure vs displacement, pressure vs time) in the required format. One positioning without reversal of the axle to proceed both sides’ wheel mounting and dismounting. Only required one operator to operate the wheel press machine. With high-pressure Oil injection pump for mounting and dismounting.

(*Above parameters are indicative, and can be modified as per customer's requirements.)
Machine features:
- The Machine is a horizontal hydraulic wheel press and will be installed in a pit.
- The 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.
- Gantry frame structure, with high strength, good rigidity and less deformation.
- Double-end cylinder pressing. Only need one positioning without reversal of the axle to proceed both sides’ wheel mounting and dismounting.
- 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 mounting requires high accuracy and high pressing force. In order to ensure that the parts blocking the wheel are subjected to the force completely symmetrical, we adopts cylindrical ram for mounting wheel, not the side opening baffle.
- An electrical support trolley is provided for wheelset pre-assembly and loading/unloading onto/off from the Machine. It will exit from the Machine during the mounting/dismounting operation.
- A gearbox support is provided 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.
- With high-pressure Oil injection pump for mounting and dismounting.
