The JCB 457 Wheeled Loader on quarry duties
JCB has unveiled the new 457 wheeled loading shovel, the flagship of the range that features a Stage IIIB (Tier 4 Interim) compliant engine.
The company says that improved transmission options, upgraded axles and robust styling combine with a revised interior to provide faster, more productive machines.
The new JCB 457 model is said to offer a 16% increase in power and 18% more torque along with intelligent clutch cut-off allows maximum hydraulic power at low travel speeds; five-speed transmission option with lock-up facility for faster acceleration and improved ride and carry performance, and automatic locking differentials for improved tractive effort.
The 457 takes over at the top of the JCB wheeled loader line-up, replacing the 456. It is powered by an 8.9litre engine delivering 186kW of power, an increase of 16% on the previous model. With a variable geometry turbocharger, high pressure common rail fuel injection and a diesel oxidation catalyst with diesel particulate filter (DPF), this powerful engine also provides an 18% increase in torque, at 1,085Nm, and meets the requirements of the EU Stage IIIB (EPA Tier 4 Interim) emissions regulations. DPF service intervals are every 5,000 hours in Europe, or 4,500 hours in North America.
“The machine is equipped with an ECO mode, which can be selected by the operator, and which reduces engine output for lighter duties and consequently achieves fuel savings of up to 6%. The 457 does not require any form of additive to provide low emissions with high power outputs,” says JCB.
