Roland Kerschdorfer, BOB The 17 Diesel trains of the “Integral” series were put into service in the early 1990s. They are currently undergoing their second overhaul inspection at the railway mainte- nance depot Lenggries. One train after another is disassembled into its individual parts. The hydraulic components are transferred to the Bosch Rexroth Service Center in Pas- ching for maintenance. They include the air-suspended, hydraulically adjustable wheel sets and the two ram cylinders, which are designed to absorb the buffer impact in case of a crash. Service, retrofitting, and reduced life-cycle costs The plant at Pasching attends to the procurement of original spare parts. It special- izes in the repair and the field service of industrial and mobile hydraulics as well as electric drives and control systems. Bosch Rexroth’s REMAN program (“remanufac- turing”) ensures reliable availability of all essential components and also provides Solved with efficient obsolescence management: parts which are no longer available can be f Uniform standards for inspection replaced with fully compatible types.
