• Girth gears can be manufactured in 2,3,4,5,6 or 8 or more segments and for both T and Y section gears
• Can be manufactured up to 50 module
• Designed and manufactured up to 14m in diameter and weight in excess of 105,000kg
• High integrity girth gears designed and manufactured to AGMA and other international standards
• Can be manufactured from either cast steel, ductile iron or forged/fabricated steel, hardness up to 320 BHN
• Provide reliable service and maintenance programs for girth gears which include full overturning capabilities
