New Case 521F Achives Better Fuel Efficiency with SCR Technology
Case Construction Equipment recently introduced the Case 521F wheel loader, offering customers a 12% increase in fuel efficiency over the previous E Series model, while delivering 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, which boasts premium features and industry-leading performance, productivity and efficiency.
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. The 4.5 l Case engine delivers 131 hp. Classified as a 1.6 m3 wheel loader, the Case 521F has an operating weight of 10,367 kg. The standard model delivers 8,889 kg of lift capacity and 7,591 kg of bucket breakout force, with hinge pin height of 3.6 m for efficient truck- and hopper-loading.
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 outstanding traction in all conditions, especially in non-compacted surfaces like gravel, and help reduce tire wear when working on hard surfaces.
The Case 521F wheel loader delivers class-leading comfort and visibility and new features to improve operator effectiveness. Case’s Quiet Cab boasts the largest cab in the industry, has a 70.8 decibel rating, and supplies cleaner air with a dual air filtration system. It also provides a more comfortable ride with an optional heated air ride seat, and ergonomically positioned controls that ensure a long day in the cab will not reduce productivity.
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. Also, the addition of over 250 new buckets, including light material buckets, rotary brooms and forks, and 4-in-1 buckets, means the 521F wheel loader offers even more solutions for a wide range of tasks. The offering includes Case SmartFit™ bucket tooth systems. The SmartFit system provides stronger, more durable teeth and adapters, and hammerless reusable locking pins to improve digging performance.
