JCB’s new 5.5-ton mini-excavator is available as both a reduced-tail-swing model (8055 RTS) and as a zero-tail-swing model (8055 ZTS). Weighing 11,464 pounds, the 8055’s design includes factory-fitted air conditioning and a combined hammer and low-flow hydraulic circuit that works with secondary auxiliary piping. According to JCB, the low-flow circuit will be particularly useful with rotating hydraulic attachments and with the company’s new hydraulic thumb. Powered by a 46.5-horsepower diesel engine, the 8055 has a maximum travel speed of 3.4 mph. At the rear of the machine, the 8055 RTS has a 2.1-inch tail-swing, and the 8055 ZTS can rotate within the width of its tracks. The two machines share an identical digging envelope, with maximum digging depth at 12 feet 4 inches and maximum reach at ground level at 19 feet 10 inches.
