3150kN Double Cylinder Horizontal Wheel Mounting And Dismounting Press

Application scope:

This double cylinder horizontal hydraulic wheel press is a fully automatic design. It's used to mount and dismount the railway wheels and gears safely and effectively for railway rolling stocks. It has two operation mode - Automatic and Manual. It can generate, record, save and print the pressing curves in the required format. Only required one operator to operate the wheel press.

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 pit. (Design without foundation pit is available.)
• Gantry frame structure, with high strength, good rigidity and less deformation.
• Double-end cylinder pressing. Only need one positioning to proceed the 2 wheels' mounting and dismounting without reversal of the axle.
• 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.
• The centre devices only bear the weight of the axle and do not bear the large pressure of the oil cylinder. While maintaining the centre positioning, it can automatically retreat back to the inside of the ram, so that the ram fits the end face of the axle and then can bear large cylinder pressure. When mounting, dismounting and back pressure test, the centre will be retreated into the center hole and the end face of the centre will fit the end face of the axle.
• 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.
• Movable slider device with at 2 replaceable inserts to block the wheels, gears or brake discs for dismounting. It's the original patent in China.
• An electrical support trolley is provided for wheelset pre-assembly and loading/unloading onto/off from the press. It will exit from the press during the mounting/dismounting operation.
• A gearbox support is provided to support the gearbox during the whole mounting/dismounting process.
• Siemens S7-300 PLC and AdvanTech Industrial computer to control the operation. User-friendly HMI.
• Only one operator required to operate the wheel press.
• The press 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.
