R3 Rotation ProgramsAlstom offers its R3 Rotation Program when a number of gearboxes require rebuilding over a period of time. This program is a systematic method for rebuilding equipment and returning it to service.

Rebuild – The gearbox is rebuilt.

Restock – Once rebuilt the gearbox is placed in the customer's exclusive stock at an Alstom facility.

Replace – The gearbox is returned to the customer to replace a similar gearbox requiring rebuilding and the cycle is continued.

  • conveyor belts
  • cooling towers
