New SCR Technology Improves Fuel Efficiency
Case Construction Equipment recently introduced three new F Series wheel loader models. The new machines provide faster acceleration, quicker cycle times and higher travel speeds while delivering as much as 17-percent greater fuel efficiency. The new Case 721F, 821F and 921F wheel loaders evolved from the company’s E Series product line. The Case F Series wheel loaders use proven selective catalytic reduction (SCR) technology to meet Tier 4 Interim emissions standards while also delivering increased power and improved fuel efficiency. The Case 721F, 821F and 921F wheel loaders feature a 6,7 l Tier 4i certified engine, rated at 179, 211 and 242 hp, respectively. A new optional, five-speed transmission with a lockup torque converter, open-differential axles and advanced system programming provides even more fuel savings. A new dual-mode shutdown feature maximizes fuel economy and monitors vital engine components. Using the fuel-saver mode, the operator can limit the time the machine will idle. The desired shutdown time can be set in five-minute increments. The new Case wheel loaders include standard limited-slip front and rear axles that provide outstanding traction in all conditions, especially in non-compacted surfaces, such as gravel. The standard four-speed transmission with manual kick-down provides maximum traction and increased bucket penetration. The Case 921F wheel loader, with a 3,6 m3 bucket, launches a new size class for Case. With greater tipping load weight and bucket breakout force relative to its payload, the 921F meets the needs of aggregate stockpiling and high-production truck-loading applications. Case Construction Equipment will be exhibiting at CONEXPO-CON/AGG 2011.
