Product Details
3500kN Automatic Locomotive Wheelset Mount Press With Double
Cylinders
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.
Application scope:
This Automatic Wheelset Mount Press machine is mainly used for the
mounting work of the wheel discs and axles of the electrical locomotive wheelsets. It can generate, record, save and print the pressing curve
(Pressure vs displacement, pressure vs time) in the required
format. It's only required one operator to operate the wheel press
machine.

Machine features:
- Only one operator is required for the whole pressing operation.
- 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.
- Double-end cylinder pressing, only need one positioning without
reversal of the axle to proceed both side wheels' mounting.
- 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.
- Overall gantry frame structure, with high strength, good rigidity
and less deformation.
- Electrical support trolley 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 process.
- Automatic recording of mounting curve, radial and axial run-out and
back pressure test of each mounted component;
- Siemens S7 PLC and Advantech Industrial computer for operation
control.
- 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 provided for oiling pressing.
