L&T designed, manufactured, constructed and commissioned India's largest ship-lift for L&T shipyard at Kattupalli near Chennai. The Ship Lift is a mega elevator which raises the ship out of the water for dry-docking ashore and lowers them back into the water on completion of work. The Ship Lift platform is lowered and raised by a number of hoists, driven by high precision variable voltage frequency drives (VVFD) with encoder based feedback system, operating in a synchronized manner. The system monitors the load and position on a real-time basis and a fail-safe double brake system ensures the safety of the Ship Lift system and ship. The Ship Transfer System consists of electro-hydraulic trolleys along with trestles, which are designed to transport ships from the Ship Lift to dry berths on land. The Shiplift has a lifting capacity of 21,050 Tonnes (expandable to 23,000 tonnes), with a platform size of 210 X 44 m.
