JCB 457 wheel loader has 16 percent more power and 18 percent more torque than its predecessor, the 456. The company’s largest loader has a 250-horsepower Tier 4-Interim diesel delivering 800 lb.-ft. of torque. Intelligent Clutch Cut-Off system allows the engine to provide maximum power to hydraulics, when the operator presses the brake pedal. It also reduces power to the driveline for greater control at lower travel speeds. Open differential axle with optional automatic differential locking provides additional tractive effort without operator input, reducing wheelspin, tire wear, and fuel consumption, JCB says. Full-color LCD monitor and revised instrument panel allow operators to access information through the screen’s intuitive menu system.
Models DL300-5, DL350-5, DL420-5, DL450-5 and DL550-5 comply with Tier 4-Final requirements
The 744K-II, 824K-II, and 844K-II wheel loaders meet Tier 4-Final emissions standards.
JCB’s 3CX and 4CX backhoe loaders now come standard with the company’s Tier 4-Interim Ecomax diesel engines, delivering up to 9 percent better fuel consumption and a 6 percent boost in torque, the company says.
JCB Ecomax diesels meet Tier 4-I requirements without external aftertreatment or DPFs
