Replacement of slip ring crane motors

Customer: Maintenance planner (Germany)

From a south German maintenance planner, Menzel received the order to produce two new 380 V slip ring motors, which work as a tandem lifting unit of a large crane. The old motors have been running for nearly 40 years. After several new windings they have now come to the end of their life. Due to the limited space on the crane, the new motors had to be a 100% dimensionally and electrically interchangeable.
