INSPECTION AND CERTIFICATION Inspection and Certification All Galbiati Group gear drives are “full speed – no load” tested for a minimum of six hours. The gear drive performance (lubrication system, temperature probes, etc.) and its accessories (ejectors, hold down rolls, etc.) are properly checked. On each new unit, as well as on the overhauled one, temperatures (oil, housing, and bearings), noise levels, and vibrations are measured and recorded on relevant test record. A “Certification File” is issued for each drive, which contains the raw materials and all the manufacturing process...
