Horizontal Railway Hydraulic Wheelset Press Machine Force 3150kN , With Double Cylinders

Application scope:

This Horizontal Wheelset Press Machine is used for the assembly, disassembly and backpressure testing of the wheel discs and driven gears of the locomotive wheelsets. It can generate, record, save and print the pressing curve (Pressure vs displacement, pressure vs time). This type wheelset press is widely used in China Railway Corporation and CRRC.

Technical parameters:

(*Above parameters are indicative, and can be modified as per customer's actual requirements.)

Machine features:

• The Machine is a horizontal hydraulic wheel press and will be installed in a foundation pit.
• Gantry frame structure, with high strength, good rigidity and less deformation.
• The Machine is able to assemble or disassemble two wheels on the axle without turning the axle.
• Double cylinders design. Only need one positioning without reversal of the axle to proceed two 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 support trolley for wheelset loading and unloading. It will exit from the Machine during the mounting/dismounting operation. The trolley can be used as a preassembly stand.
• The Machine is equipped with a gearbox support to support the gearbox during the whole mounting/dismounting process.
• The whole operation is controlled on the industrial computer and PLC. the computer can record and export the pressing curves.
• The Machine is designed with acoustic-light alarm to ensure the safe and reliable operation.
• High pressure oil injection pump is provided for oil mounting and dismounting.
• Only required one operator to operate the wheel press machine.
