The windlass, traction machine, and tow machine with the maxim rated single cable pull of 34t are available. They are powered by electromotor, diesel engine or petrol engine, operated and adjusted manually or electronically with non-standard low speed or high speed, single roller or twin roller. The integrated ship towing system (the cargo ship with the dead weight of 4000t on the sideway of gradient of 7%) was exported to the Southeastern Asian market and won positive response there. The windlass with folded cable groove independently developed by HLCM since 2003 has proven a great success as the most advanced technology in the filed nationwide. It has been applied as the main lifting windlass safely and reliably in the 400t walking cantilever bridge crane in the Shanghai East China Sea Bridge project.
