500t Railway Horizontal Wheel Press-fitting Machine With Double
Cylinders With Oil Injection System
Application scope:
This 500t Horizontal Hydraulic Wheel Press machine is
mainly used for the mounting (colding pressing and oiling pressing) and
dismounting of the HXD series locomotive wheelsets. It can generate, record, save and print the pressing curve
(Pressure vs displacement, pressure vs time). It's only required
one operator to operate the press. With High-pressure oil injection
pump for pressing operation.

Machine features:
- The Machine is a horizontal hydraulic wheel press and will be
installed in a pit. (The model without pit is also available.)
- 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/dismounting.
- The 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 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.
- The 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 Machine 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.
- High pressure oil injection pump is suppled for oil mounting and
dismounting.
- Only required one operator to operate the wheel press machine.
