CX145C SR Full Size Excavator

Unlike traditional excavators with prominent rear counter-weights, the CASE CX145C SR excavator features a compact counterweight and boom placement that minimizes the machine’s work envelope. The small swing radiuses make maneuvering onto difficult, restricted sites a breeze. Daily maintenance on the CX145C SR is made easy with service checks from ground level and extended maintenance intervals. Tier 4 engines meet current environmental standards while lowering fuel consumption.
