Wind and industrial gear manufacturer Moventas has launched new custom-built mobile service units for wind gears.
The entire helical side of the gearbox can be repaired up-tower, thus shortening repair times and eliminating the need to ship gears to and from service centers, the company explains, adding that fewer lifts and smaller components reduce weather delays.
Moventas launched its up-tower repair service last year and now offers full helical up-tower service on both Moventas gears and non-Moventas gears. Designed to support Moventas' up-tower field-service program, the self-contained, climate-controlled mobile workshops are outfitted with a retractable roof, a power generator, plumbed air lines, a parts wash basin and an induction heater.
In the case of a full helical repair, each gearbox Moventas services up-tower is equipped with CMaS, the company's condition management system. CMaS performs vibration analysis and tracks changes in oil condition and particle counts every 15 minutes, allowing it to catch potential problems, the company explains. CMaS data is analyzed remotely by Moventas' engineers, who then alert customers about potential problems before they occur.
