Hydraulic Locomotive Wheelset Press 350 Tons Double Head Cylinders

350 Tons Double Head Locomotive Wheel Mount Press Wheelset Press

Hubei Heqiang Machinery is the leading manufacturer of wheel set press machines in China. It offers the most advanced wheel presses 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.

Application scope:

This Double head Wheelset Mount Press is used for the mounting work of the wheel discs and axles of the locomotive wheelsets. It can generate, record, save and print the pressing curves. It's only required one operator to operate the hydraulic wheel press. A high-pressure oil injection pump can be provided for easy oiling pressing.

Technical parameters of the Hydraulic Wheel Press:

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

Machine features of the Horizontal Wheelset Press:

• The Wheel Mount Press is a horizontal hydraulic wheel press and will be installed in a pit.
• The Wheel press-fitting 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.
• 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 Wheel Press 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 Wheel Assembly press Machine is designed with acoustic-light alarm to ensure the safe and reliable operation.
