315t Automatic Metro Wheelset Press With 180° Rotary Support Trolley
Application scope:
This 315t automatic wheelset press is used to mount and dismount the wheelset wheels and gears of the type A and B metro cars. It's also applicable for the mounting and dismounting work of wheelsets of the low floor vehicles. It can generate, record, save and print the pressing curve (Pressure vs displacement, pressure vs time) in required format. It only needs one operator to complete all the pressing procedures.

Machine features:
- The wheel press machine is a horizontal hydraulic wheel press and will be installed in a foundation pit.
- The wheelset press is able to mount/dismount both wheels on the same axle simultanously without turning the axle.
- One positioning to mount/dismount the 2 wheel discs without reversal of the axle.
- Double-end cylinders for mounting and dismounting.
- Movable slider device with at 2 replaceable inserts to block the wheels, gears or brake discs for dismounting. It's the original patent in China.
- Overall Gantry frame structure design, with high strength, good rigidity and less deformation.
- 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.
- A Rotary support trolley for wheelset pre-assembly and loading/unloading onto/off from the press. It will exit from the press during the mounting/dismounting operation.
- 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.
- High pressure oil injection pump is available for option;
Overview of Hubei Heqiang:
Hubei Heqiang Machinery is the leading manufacturer of wheel set press machines in China. It now covers more than 80% of the China market. We offer 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.
Our fully automatic double cylinder wheelset press is the most advanced wheel press machine available on the market today. Available in capacity ranging from 200 to 500 tons. This machine features a precisely positioned cylinder on each side of the machine along with our state-of-the-art measuring system that utilizes a high-tech servo system and a series of analog laser measuring devices to position each wheel-set component with high precision. All tooling is specialized and easily exchanged to safely accommodate a large variety of wheel set components and configurations. A rotation device are optional to be 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.
