Repair Service / Competencies

Our modern and efficient workshops are located in Burgwedel (near Hanover), Hamburg, and Bremerhaven. As a certified specialist company, our core competencies lie in the diagnosis and repair of electric motors, gearboxes, and frequency converters. Of course, we also have decades of experience in servo and pump technology, as well as in hoists, heavy-duty magnets, and agitators.

We are also authorized to repair and test explosion-proof drives. With over 28,000 different items in stock, we can offer a rapid repair service without long procurement times. To prevent the parts you need from being sold in the meantime, we recommend reserving the required items in advance for scheduled repair work. We offer a full repair service! On request, we can provide on-site disassembly and assembly, commissioning, and preventive and condition-based maintenance. We can also offer regular maintenance, including measurement, alignment, and balancing, as well as a repair transport service. Our own winding shops and a wide range of mechanical processing methods, including shaft machining and flame spraying, round off our service offering.
