PORT & RIVER PRODUCTS: In 1970, Interstate expanded its materials handling product line to include Port and River Products. These engineered products provide waterway operators safe, secure and dependable solutions designed to minimize barge handling costs. Products include barge mooring systems, barge haul systems, continuous breasting cable systems, work barge facilities, barge cover pulling systems and powered sliding sheave systems. The basis for the barge breasting system is a unique one-time connection to continuously control the barge: thus eliminating constant tie-offs as the barge moves through the dock.
