Our partner KOLTECH is specialized in the production of mechanical machines and devices for rail vehicle maintenance and repair facilities.

The underfloor wheel lathes types, TUP 650, TUP 650H and TUP 650SH are designed for reconditioning of wheel profiles of all ranges of rail vehicles.

The machining process is carried out without the necessity of dismantling the wheelsets from the vehicle.

TUP 650 lathe is designed for light rail vehicles like tramways where single axle load does not exceed 10000 daN whereas TUP 650H lathe is for e.g. traction units of subways where single axle load does not exceed 17000 daN, and TUP 650SH lathe is for railway applications where single axle load does not exceed 30000 daN.

TECHNICAL SPECIFICATION

Standard equipment of underfloor wheel lathes TUP:

• SIEMENS CNC SYSTEM SINUMERIK 840D
• Input-Output system (PLC), based on PROFIBUS solution
• TOUCH AND GO operator’s panel, supported by visualization of technological cycles in operation
• Hydraulic power pack and hydraulic apparatus
• Oil cooler
• Swarf protecting guards and swarf chute
• Hold-down devices (only for TUP 650H and TUP 650SH)
• Operation and Maintenance Manual
• Diagnostics of disturbances in operation
• Audio-visual warning and signalling system
• Measuring heads

Applications:

• The models TUP 650/H/SH can be adapted for 3 kind of centering:
  • In centres and/or inner axle box supports – TUP 650
  • In outer and/or inner axle box supports – TUP 650H
  • In outer axle box supports – TUP 650SH
• Frictionless linear guideways with needle bearing cages for saddle and slide travels.
• Hydraulic drive motors for rollers drive, for differing the speeds of particular driving rollers with simultaneous preservation of equal distribution of torque- perfect synchronization.
• Measuring heads for position of saddles in relation to wheels of the same axle
• Measurement of wheel tread diameter
• Measurement of height and thickness of flange
• Measurement of wheel back to back distance
• Wear measurement and optimization of cutting depth
