Full rebuild of tunneling machines


Tunnel Service Group GmbH offers full rebuilds for microtunneling machines. The machine is taken apart and each component is either replaced or refurbished individually in-house or by external specialized companies. Steering cylinders and position sensors are refurbished by the manufacturer, the main bearing is tested and if necessary refurbished by a renowned German bearing manufacturer; gate or ball valves and steel pipings are refurbished or replaced. All wear parts, hydraulic hoses and sensors or cables where necessary are replaced; steelworks are repaired, sandblasted and repainted. After reassembly the machine is nearly a new machine.
