Case F series meets Tier 4 Interim standards with SCR technology

Case Construction Equipment introduced its 621F wheel loader model at the World of Concrete 2012 in Las Vegas earlier this year. The new vehicle provides up to a 10 percent increase in fuel economy over the previous model, while delivering faster acceleration, quicker cycle times and higher travel speeds.

Like other models in the product line, the 621F evolved from the company’s E Series machines. To meet Tier 4 Interim emissions standards, the Case F Series wheel loaders use selective catalytic reduction (SCR) technology, which results in lower temperatures in the exhaust system while optimizing combustion. “Case wheel loaders already led the industry in fuel economy, but the addition of SCR technology in our Case F Series wheel loaders expands that leadership position,” said Tim O’Brien, Case's brand marketing manager. “At the same time, we’ve added more power and responsiveness to provide contractors with the combination of performance and economy they need to compete successfully.”

The Case 621F features a 6.7-liter Tier 4 Interim-certified engine that delivers up to 162 hp. Classified as a 2.75-cu.-yd. wheel loader, it has an operating weight of 26,641 lb.

Significant fuel savings
“The 621F delivers the best fuel economy and performance in its class size,” O’Brien said. “Like other F Series models, the 621F offers four programmable power modes to save fuel and increase available power. These easy-to-program power modes—Economy, Standard, Max and Auto—give operators flexibility in matching engine power to their jobs.”

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 automatic engine shutdown feature can provide up to another 30 percent in fuel savings, according to O’Brien.

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. Optional heavy-duty axles with locking front and conventional rear differentials help reduce tire wear when working on hard surfaces. The standard four-speed transmission with manual kick-down capability provides maximum traction and increased bucket penetration.

The award-winning Case joystick steering enables operators to seamlessly move between the joystick and steering wheel for high-production operations. An optional two-lever hydraulic control system is available. The Case PowerInch feature lets the operator quickly and precisely approach targets in tight areas, regardless of engine speed. PowerInch maintains high RPMs to maximize hydraulic power and control.

The Case 621F is the latest F Series wheel loader model to provide enhanced comfort and safety features that help boost operator productivity. The cab offers an unobstructed view to both edges of the bucket or attachment, while a wide window and sloping hood provide clear vision to the rear.

A new rearview, wide-angle camera with an adjustable color monitor is available in the Case F Series. The camera option nearly eliminates blind spots and is ideal for jobs that require operating around other machines or workers.

“A machine with excellent visibility to all corners of the vehicle improves everyone’s safety on a busy jobsite,” O’Brien said. “The Case F Series wheel loaders offer best-in-class rear visibility and a panoramic view to the front and sides.”

The Case 621F wheel loaders include an advanced instrument cluster that monitors fuel consumption and enables the operator to adjust various functions without relying on a service technician. All Case F Series models also offer ergonomically placed controls and a new heated cloth seat with seven adjustment modes. www.casece.com
