From World of Concrete: Case introduces F Series wheel loaders
Case Construction Equipment introduced three new F Series wheel loader models on Jan. 18 at the 2011 World of Concrete in Las Vegas.
The new machines provide faster acceleration, quicker cycle times and higher travel speeds while delivering as much as 17-percent greater fuel efficiency, according to the manufacturer.
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.
“With the SCR technology in our Case F Series wheel loaders, Case has made what was already the industry’s most fuel-efficient line of wheel loaders even more fuel efficient,” said Tim O’Brien, marketing manager for Case Construction Equipment, in a written statement. “At the same time, the Case F Series engines are more powerful and respond faster.”
The Case 721F, 821F and 921F wheel loaders feature a 6.7-liter Tier 4 Interim-certified engine, rated at 179, 211 and 242 hp (133, 158 and 180 kW), respectively.
Significant fuel savings
“These new Case wheel loaders deliver uncompromising leadership in fuel economy and performance,” O’Brien said. “To start with, we updated the four programmable power modes to save fuel and increase available power.” He explained that use of the easy-to-program power modes – Economy, Standard, Auto and Max – gives operators flexibility in matching engine power to their jobs.
A new optional, five-speed transmission with a
lockup torque converter, open-differential axles and advanced system programming provides even more fuel savings. “The five-speed transmission offers good value, with an 8-percent increase in fuel savings over a comparably equipped model with a four-speed transmission,” he added.
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 4.75 yd3 (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. Bucket capacities are 3.25 yd3 (2.5 m3) for the 721F and 4.25 yd3 (3.25 m3) for the 821F.
“The Case F Series wheel loaders can perform in a wide range of applications, from construction sites and landfills to quarry and aggregate operations,” O’Brien said.
