Hubei Heqiang Machinery has been developing and supplying assembly and disassembly presses for wheelsets of rail vehicles for over 20 years. Whether you need to press wheels, brake discs, gear wheels, journal bearings or gearboxes, whether high-speed trains, metros, trams, EMU, locomotives, coaches or wagons, we have the right solution for you.
Horizontal Wheelset Mounting and Demounting Press
The hydraulic wheelset press is a horizontal design for mounting and dismounting the wheelset elements, such as wheels, gears, brake discs, etc, and for the back pressure test (if required) of rail high-speed trains, metros and EMU).

Product Features:
- The press is fully automatic and only one operator is required to complete all the operation.
- After the wheelset is transferred to the press and positioned in the press, the press will carry out both side wheel mounting or dismounting, no need to turn the axle 180°.
- The machine bed of the wheel press adopts an overall gantry frame structure. It provides a rigid frame with high strength and stability so as to smooth the operation with vibration free.
- The press is provided with double-ended ram cylinders for mounting and dismounting.
- A centering device is mounted at each end of the piston rods for aligning the center of the axle with the center of the ram cylinders and clamp the axle.
- A cylindrical ram is mounted at each end face of the ram cylinders to block the wheel hub for wheel mounting.
- A mobile slider device is mounted on the machine bed for dismounting wheels, as well as mounting and dismounting of brake discs and gears etc.
- A motorized wheelset transferring trolley is provided for wheelset loading and unloading. The trolley will lift the axle to the center of the press to assist the centering devices for axle positioninge. The trolley will exit the press during the operation.
- A gearbox support is provided to support the gearbox. It will keep supporting the gearbox during the operation.
- The electrical control unit is provided with both Manual and Automatic operation mode. It provides the measurement and recording system to record and save the detected data in the system.
- A wheel measurement unit is mounted at the upper crossbeam of the machine bed to detect the wheel position and wheel back-to back distance.
- Force sensors and displacement sensors are provided to real-time detect the pressing force applied and the displacement of the piston rod for the control system to plot the force vs displacement curve on the screen of the industrial PC. The force vs displacement diagram can be printed on the supplied printer to provide a permanent record or save and export via a USB drive.
