Horizontal Hydraulic Wheelset Press, Wheelset Mounting and Dismounting Press
Application scope:
This horizontal wheel press is a fully automatic design. It's used to mount, dismount and back-pressure test the wheels and brake discs safely and effectively for railway metro, intercity vehicles and high-speed trains. With pre-fitting stand. With measurement and curve recording system.
This hydraulic wheel press is applicable for the wheelset with bearings at inner side of wheels.
2) Only one operator required to operate the wheel press.
3) Gantry frame structure, with high strength, good rigidity and less deformation.
4) Double-end cylinder pressing.
5) Unique Invention patented cylindrical ram for wheel mounting, with high pressing accuracy.
6) Only need one positioning to proceed the 2 wheels' mounting and dismounting without reversal of the axle.
7) 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.
8) The centre devices only bear the weight of the axle and do not bear the large pressure of the oil cylinder.
9) Movable slider device with replaceable inserts to block the wheels, gears or brake discs for dismounting.
10) An electrical support trolley is provided for loading/unloading onto/off from the press.
11) With a pre-fitting stand for wheelset preassembly.
12) Siemens S7-300 PLC and AdvanTech industrial computer to control the operation.
13) 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.
