JonRie commissions Series 220 escort winch on new z-drive tug


(MANAHAWKIN, N.J.) — JonRie Marine Winches has commissioned its new Container Master Series 220 double-drum escort winch on the tugboat Independent, a new z-drive vessel for Marine Towing of Tampa, Fla.

The Container Master Series 220 double-drum bow winch was designed for a larger capacity rope. This concept used on the Panama Canal for many years as a redundant line tethered to the ship also acts as an escort bridle, making the tug more stable in prop wash during long escorts. The twin drums also afford less loading on each rope under braking. Both drums feature JonRie’s constant tension systems.

All winches on the tug feature independent drives for each drum and JonRie’s standard foot pedal for hands-free operation. Also featured on each drum is JonRie’s side light with dimmer tension read-out system. The tension meters also include an adjustable alarm pilot light so when a preset tension is selected, it will alarm the master of an overload when exceeded. The winch has the capacity to spool 600 feet of 9-inch hawser, with an 18-ton line pull and a line speed of 100 feet per minute.

All winches have an auto abort system and a backup 24 VDC system if power is lost on the tug. All controls, soft starter and 75-hp HPU are the design and supply of JonRie. For more information, visit
