Case adds to wheel loader line

Case Construction Equipment, Racine, Wisconsin, has introduced the 521F wheel loader that meets federal Tier 4 Final emissions standards using selective catalytic reduction (SCR) technology. The new machine delivers best-in-class 131 net peak horsepower with an FPT Tier 4 Final-certified engine that also provides quick throttle response, according to the company.

The 22,948-pound wheel loader has a bucket breakout force of 19,303 pounds with 2.3-cubic-yard bucket capacity.

The SCR technology allows the machine to handle inconsistent engine loads while running at peak performance without compromising power, the company says. This is accomplished with a faster throttle response and acceleration, all while maintaining lower exhaust temperatures and improving fuel efficiency.

Case explains that with SCR technology, the 521F Tier 4 Final wheel loader features 10 percent greater fuel economy over wheel loaders featuring cooled exhaust gas recirculation/diesel particulate filter (CEGR/DPF) solutions. Additional fuel savings are achieved with a standard auto-idle feature that helps minimize excessive fuel burn during operator inactivity by further lowering engine RPM. Standard auto shutdown then stops the engine after an operator-selected length of time to further preserve fuel. The SCR-only approach found on the new 521F also contributes to machine uptime by eliminating the need for manual DPF regeneration and the associated downtime that can occur with wheel loaders that use CEGR technology, Case explains.

As an after-treatment system with minimal components, there is no need for recirculation equipment or a DPF for lower long-term maintenance costs, the company says. Additionally, SCR results in extended time between service intervals as lower ambient exhaust temperatures result in slower degradation of engine components and less demand on the coolant system.

Like the rest of the F series lineup, the 521F wheel loader incorporates hydraulics in addition to a host of features that further enhance machine efficiency and productivity, Case says. Among them are:

 

 

To help boost the operator experience, the 521F wheel loader features the Case Quiet Cab, the largest cab in the industry, according to the company. Case explains the dual air filtration system, optional heated air-ride seat and insulated cab mounts provide a clean, quiet operating environment while floor-to-ceiling windows, an improved lighting system and optional rearview camera provide visibility all around the machine. The 521F also features an award-winning joystick steering option and an advanced instrument cluster with four selectable power modes (economy, standard, max and auto) for precise, intuitive control.

The 521F features the exclusive Case midmounted cooling system. Unlike stacked coolers on other machines that transfer hot air to the inner coolers, Case says its cooling system is configured like a cube with all coolers facing fresh and cool ambient air. This improves the effectiveness and efficiency of the cooling system, the company says.

The 521F wheel loader is covered under Case ProCare—the industry’s first all-in-one heavy machine support program, according to Case. ProCare includes a suite of product assurances that include a three-year Advanced Case SiteWatch telematics subscription, a three-year/3,000-hour full-machine factory warranty, and a three-year/3,000-hour planned maintenance contract. ProCare allows business owners to invest in new equipment while helping to make owning and operating costs predictable for the first three years of ownership.

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