Chocks for the 251,000 pound Diesel on the BT-100 were cast with PR610TC for: ? Superior Alignment ? Reduced Vibration ? High Impact and Compressive Strength ? Lower Installation Cost The BT-lOO Hydraulic Dredge is owned and operated by T. L. James & Co., Inc., Ruston, La. It has a steel hull 186' x 48' x 13' and is be-lieved to be one of the heaviest constructed dredge hulls in the Gulf Coast area. This V-16 Enterprise Diesel is considered to be the largest 4-cycle diesel engine made in the U. S. It weighs 251,000 pounds, and is rated at 6150 HP at 375 rpm. PR610TC eliminates costly machining of metal chocks and offers an anti-corrosive, 100% contact, liquid-level chock that re-duces vibration and resists chemical attack. On the BT-100, chocks of PR610TC were cast, not only for the huge diesel engine, but also for the thrust and support bearings of the drive shaft to the pump.
