June 2016 | EquipmentWorld.com 12 marketplace | continued JCB debuts compact excavators JCB unveiled its 48Z-1 (pictured), 55Z-1 and 57C-1 compact excavators. The 10,000-pound 48Z-1 replaces the 8045Z and the 55Z-1 replaces the 8055ZTS/RTS model. The 57C-1 is a new size category for the company. Machine features include redesigned pin pickup points that are com- patible with a variety of attachment brands, including JCB's new range of ECO buckets, which have a redesigned profile for easier filling and improved material retention. The rede- signed digging end uses a longer main boom and shorter dipper arm or stick to provide up to 5 percent greater dump height to ease truck loading, says JCB. In addition, the upgraded hydraulic system has up to 9 percent more bucket breakout force and 2 percent higher dipper arm breakout than previous models. Bell 60-ton prototype to be here by year's end The Bell B60E, directed at quarry and mining opera- tions and shown as a prototype at Bauma, will use a 4×4 all-wheel-drive configuration rather than the more typical 6×6. Bell says the shorter machine gives the machine a tighter turning circle; with only a single axle in the back, tires are also less prone to scuffing. The company adopted the two-axle concept of a rigid truck– which the B60E is designed to replace in some applica- tions – with a driven front axle and independent front and rear chassis. The back axle is a 70-ton Kessler truck axle, and the bed is wider than a typical ADT, resembling that on a rigid frame truck. Telescopic cylinders tuck under the bed to push it up in stages during the tipping process. A cradle supports the rear axle with struts being used to create shock absorption. The truck is expected to be introduced in North America by the end of the year. Genie boom lift offers two modes of operation Driven by high-efficiency AC motors, the new Genie Z-60/37 FE boom lift provides two modes of operation: full- electric or hybrid. The machine can run a full week on a tank of diesel in the hybrid mode. In full-electric it has enough power to run for a day. A 24-horsepower, Tier 4 Final engine drives the unit in the hybrid phase and charges a 48-volt battery system. When the batteries are exhausted, a bulk charge operation using the diesel engine can bring them back to full charge within about four hours. The boom lift can climb grades as steep as 45 percent. The Genie Z-60/37 FE has a working height of 65 feet 7 inches with a horizontal outreach of 36 feet 7 inches, and up-and-over clearance of 24 feet 3 inches. A standard 5-foot jib offers 70 degrees up and 65 degrees down range of motion. The platform will rotate 160 degrees and hold up to 500 pounds.
