JonRie supplies its fifth ship set of full bollard pull winches to McAllister Towing

JonRie Marine Winches supplied its fifth ship set of full bollard pull winches to McAllister Towing of New York, installed on their new tug Tate McAllister. The 92-by-32-foot z-drive tug was designed and built by Washburn & Doughty of East Boothbay, Maine. The 6,000-hp tug with a bollard pull of 90 tons is the latest addition to the McAllister fleet.    

The JonRie Series 250 Escort Winch was designed to handle in the recover mode the full bollard pull of the vessel. The winch is capable of 180,000 pounds of line pull and makes the winch ideal for escort work, LNG terminals and ship assist of the new containerships to come through the new Panama Canal expansion. The addition of the Tate makes McAllister the largest fleet on the East Coast with high horsepower tugs and super duty winches.

The winch also has active heave compensation (full render/full recover) that will also allow the tug to free wheel away for its tow and also heave in at any speed. The winch system also includes JonRie’s standard foot control to allow for hands-free operation of the winch – press down to pay out and heal back to haul in. Also included in the system is JonRie’s tension readout system with side lights and dimming for night use. The winch drum has the capacity to spool 500 feet of 8-inch hawser, a brake capacity of 600,000 pounds and a line speed of 100 fpm. The direct-drive design allows for quick response to fast loading inertia that an escort winch must endure. The 300-hp hydraulic power unit (HPU) and controls are all the in-house design of JonRie InterTech LLC. www.marinewinch.com
