Case Announces New 521F Wheel Loader at World of Concrete

Feb. 8, 2013
Case Construction Equipment last week announced the new Case 521F wheel loader at the World of Concrete trade show in Las Vegas.
The new Case 521F wheel loader provides a 12-percent increase in fuel efficiency over the previous E Series model and is Tier 4i compliant.

Case Construction Equipment last week announced the new Case 521F wheel loader at the World of Concrete trade show in Las Vegas. The new wheel loader offers customers a 12-percent increase in fuel efficiency over the previous E Series model, and is designed to deliver faster acceleration and quicker cycle times. The machine is available in standard Z-bar, extended reach and tool-carrier models, and is the latest offering in the company’s F Series wheel loader line.

Case chose selective catalytic reduction (SCR) technology for the 521F to meet Tier 4 Interim emissions standards based on the machine’s application tasks and power demands. SCR results in lower temperatures in the exhaust system while optimizing combustion.

“SCR was the obvious choice for the 521F because a wheel loader’s tasks are more variable, creating inconsistent engine loads and power demands,” said Rob Marringa, brand marketing manager, Case Construction Equipment. “Rather than compromise power, we let the engine do what it does best — run at peak performance — and then use an after-treatment for emissions.”

According to Marringa, the benefits of SCR technology are greater efficiency and reduced downtime because there’s no heightened fuel burn or diesel particulate filter regeneration. In addition, lower ambient temperatures means slower degradation of lubricating oil, which extends service intervals. Furthermore, fewer engine components means less crowding under the hood and easier access to service points.

“At Case, we’re committed to matching the technology with the task, and we believe that SCR technology for our F Series wheel loaders is the simplest, most powerful and efficient solution,” Marringa said.

The new 521F wheel loader offers optional heavy-duty axles, enabling it to perform more tasks such as operating in scrap yards or recycling centers. These axles, with auto-locking front and open rear differentials, have the same design as the larger F series wheel loader axles, including metal face seals and sintered bronze brake linings. They offer traction in all conditions, especially in non-compacted surfaces like gravel, and help reduce tire wear when working on hard surfaces.

“The heavy-duty axles have superior sealing capability and longer service lives, improving owner and operator costs,” Marringa said. “In addition, they can accept higher load capacities, allowing operators to configure the unit with solid, foam-filled or chain-wrapped tires.”

On a 50-meter loading and dumping cycle, Case estimates the 521F wheel loader can make up to 56 cycles per hour, moving up to 144 cubic yards or 212 tons of material per hour.

The 521F wheel loader can handle heavier and much larger buckets thanks to the Case coupler system that pulls the attachment closer to the machine, providing significant breakout. The coupler is compatible with both JRB and ACS attachments.

The Case 521F features a 4.5-liter Tier 4 Interim-certified Case engine that delivers up to 131 gross hp. Classified as a 2.1 cubic yard wheel loader, the Case 521F has an operating weight of 22,856 pounds.

Case Construction Equipment sells and supports a full line of construction equipment around the world, including loader/backhoes, excavators, motor graders, wheel loaders, vibratory compaction rollers, crawler dozers, skid steers, compact track loaders and rough-terrain forklifts.
