How do you keep a gearbox running in good condition for 37 years? Holcim Untervaz knows, having operated the same FLSmidth MAAG Gear P2U3 gearbox at its plant since 1974. Regular services have kept the gear running in fine condition, but what would a major overhaul show?
During the 37 years from February 1974 until 2011, FLSmidth MAAG Gear has visited the plant 38 times. Regular inspections were carried out, the alignment was checked frequently and the gear was kept in good condition. In addition, the local Holcim maintenance team carried out daily maintenance work...Finally, in 2011, after approximately 200 000 operating hours, a major overhaul was carried out by FLSmidth MAAG Gear service engineers. All-encompassing tests regarding the condition of internal and external parts of the gear took place onsite and also in laboratories.
