Third-party business data puts the workforce at around 50 employees; the company does not publish a figure. Alongside its machine tool business, Koltech runs a separate division reselling and implementing Dassault Systèmes product lifecycle management (PLM) software, including the 3DEXPERIENCE platform.
The company operates a joint venture in China, Qinghai Huading Koltech Machine Tools, based in Xining, Qinghai province.
Products
The core rail portfolio is the TUP series of CNC underfloor wheel lathes, which recondition wheel profiles in situ without dismantling the wheelset from the vehicle. The series covers three axle-load classes — TUP650 for light rail vehicles up to 10,000 daN per axle, TUP650H for metro-class vehicles up to 18,000 daN, and TUP650SH for railway vehicles up to 30,000 daN.
Each model is also available in tandem configuration, allowing simultaneous machining of both wheelsets of one bogie. The above-floor programme centres on the TUU1250, a friction-drive wheel lathe for turning profiles of both new and used wheelsets in roll-in/roll-out operation.
The portfolio is completed by diagnostic stations for automatic, contactless measurement of wheel profile and diameter (VIDIgo and PZK2), the PZD150 ring rolling machine for fitting safety rings in wheelset tyres, and the WM series of rail shunters for moving vehicles within workshops.
Koltech provides installation, commissioning, operator training, spare parts and warranty and post-warranty service, delivered on site, remotely or through trained local service partners.
