Electric Anchor Handling and Towing Winch with LOADLIM™ Safety System with LOADLIM Safety System The National Oilwell Varco ® line of electric driven Anchor Handling and Towing (AHT) Winches is based on decades of experience in winch design. The equipment design is based on use onboard AHTS vessels. The winch is powered by standardized and high efficient drive units each driven by four to eight Permanent Magnet Motors. Each drive unit has the LOADLIM™ Safety Release and High Speed Payout System, integrated into the gearbox. The NOV ® AHT Winch System combines the best technology available for rotating machinery, providing excellent tension control for the operator and a highly redundant drive system.
