Five compact CX B Series excavators—CX17B, CX27B, CX31B, CX36B, and CX50B—have zero-tail swing and a center-swing boom that enables operation in tight spaces, while also retaining large excavator features such as an undercarriage with heavy-duty travel motors for excellent speed and traction, and heavy plate guards that prevent damage to the hydraulic lines. They’re equipped with a hydraulically controlled backfill blade for stability and light dozing work. Case Construction Equipment. 866-542-2736.
