500t Wheelset Demount Press Cell for Wagon Wheel Disassembly
Application scope:
This Automatic Wheelset Demount Press Cell (Wheel dismount line) is used to dismount the wagon wheelsets (wheels and brake disc).
The Wheelset Disassembly Cell consists of:
- 1 set of wheelset loading trolley
- 1 set of double cylinder wheelset demount press
- 2 set of wheel overturning and stacking machine
- 1 set of Axle storage rack
- 2 set of Brake disc storage rack
Operation procedure:
- First, the movable baffle devices of the wheelset press move to the set position
- The the wheelset rolls onto the loading trolley and the trolley delivers the wheelset into the press and make the wheels insert into the baffle devices
- The trolley exits out of the press
- The Press rams extend out to dismount the wheels and brake disc.
- The baffle devices retract and the dismounted wheels rolls onto the wheel overturning machine, overturned and stacked, and lifted away by crane.
- Meanwhile, the trolley goes to pick up the dismounted axle and sends it to the axle storage rack, and lifted away by the crane.

Performance Features of the Wheelset Disassembly Press:
- Automatically dismount the 2 wheels on the same axle simultanously without turning the axle and in a sequence first the wheel at one side of the axle then the wheel at the other side.
- Both automatic and manual mode are available for option.
- The wheelset 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 measurement unit will automatically detect and collect the relevant data and display it on the screen.
- Overall gantry frame structure, with high strength, good rigidity and less deformation.
- Movable baffle devices for dismounting the wheels.
- Double ram cylinder pressing.
- Special patented centring mechanisms for center hole positioning.
- Adopt Siemens S7-300 PLC and AdvanTech Industrial computer to control and achieve the fully automatic pressing operation.
- Standard roll-in or pass-through design.
- With self-diagnosis function.
