The GW | Gearbox overhauling
of all different types and for almost all types of heavy industries is a core competence of Gustav Wiegard MASCHINENFABRIK.
We repair crane gears (lifting gears, track gears), spur gears, planetary gear boxes, worm gear units and adjust gear boxes and others. They are all repaired according to the technical instructions of the customers (drawings, technical specifications etc.).
In case the drawings or technical specification are missing, Gustav Wiegard MASCHINENFABRIK has the possibility to calculate the complete gear-toothing data by means of computers. We can also determine original materials used for the production of toothed wheels, pinions, shafts etc. thanks to a spectro-analysis device.
All the repairs follow the same routine and accuracy: Receipt of the goods, cleaning, detailed inspection, photo and video documentation, cost evaluation, final discussion and agreement about scope of repair with customer, provision of a week-to-week repair schedule, execution of the repair, final inspection and functional test at our workshop together with the customer.
Our CNC-controlled machinery with high-end toothing and tooth-flank grinding machines offers you flexible and high-performance services.
