LAS VEGAS (March 22, 2011) ‚Äď Case Construction Equipment expanded its new F Series wheel loader product line with two all-new models, the 1021F and 1121F. The products expand the Case wheel loader line into a new size class. The machines are specifically engineered for quarry, aggregate and truck-loading applications.
‚ÄúCase is taking the industry lead with the new F Series wheel loaders,‚ÄĚ said Tim O‚ÄôBrien, Case marketing manager. ‚ÄúWe‚Äôve launched these Case wheel loaders with new highly-efficient, high-horsepower engines and advanced SCR emissions technology. So the machines will respond faster‚ÄĒand you‚Äôll save fuel.‚ÄĚ
O‚ÄôBrien added that operators will boost their productivity with F Series enhancements like joystick steering, selectable power modes and a rearview camera. He also pointed out that Case is introducing an all-new hydro-mechanical transmission package. ‚ÄúThis will provide additional fuel savings, faster acceleration and faster hydraulic cycle times. The bottom line is F Series wheel loaders will out-produce other machines at a lower cost,‚ÄĚ he said.
The two new F Series wheel loaders join the current 721F, 821F and 921F line up.
- The 1021F features a 296 hp (221kW) engine, a 5.5-yd3 (4.2-m3) bucket, a dump height of 121 in (3075 mm) and an operating weight of 53,500 lb (24 318 kg).
- The 1121F, rated at 320 hp (239 kW), has a 6.25-yd3 (4.8-m3) bucket, a dump height of 126 in (3200 mm) and an operating weight of 60,800 lb (27 636 kg).
Case designed the new 1021F and 1121F Series wheel loaders from the ground up for the aggregate and quarry market to boost operator productivity and reduce owning and operating costs.
To increase productivity and meet Tier 4 Interim emissions standards, Case is the first manufacturer to introduce selective catalytic reduction (SCR) technology for wheel loaders.
‚ÄúWith the SCR technology, Case is making what was already the industry‚Äôs most fuel-efficient line of wheel loaders even more fuel efficient,‚ÄĚ explained O‚ÄôBrien. ‚ÄúAt the same time, the F Series engines ‚Äėbreathe freer‚Äô than engines with a cooled exhaust gas recirculation (CEGR) solution. This lets wheel loaders respond to the throttle faster.‚ÄĚ He said in addition to letting the engine generate power easier, other advantages of SCR technology include improving fuel efficiency and reducing long-term maintenance costs.
The 1021F and 1121F wheel loaders provide fast acceleration, quick cycle times and high production. The new high-horsepower Case engines also feature variable-geometry turbochargers. In addition, the Case wheel loaders have four power modes‚ÄĒEconomy, Standard, Max and Auto‚ÄĒto let operators match the engine power to their needs.
A new idle-management feature maximizes fuel economy and allows owners to meet local idle reduction regulations. Using the fuel-saver mode, the operator can limit the time the machine idles in five-minute increments. Helping to protect the engine is a standard diagnostic and engine shutdown feature.
New hydro-mechanical transmission
The new Case 1021F and 1121F wheel loaders are available with the industry‚Äôs first hydro-mechanical transmission. It offers all the advantages of hydrostatic drive, along with the durability and features of a conventional mechanical transmission.
The new transmission intelligently adjusts the mix of power delivery depending on travel speed. The hydrostatic pumps and motors work at lower speed for quick response, smoothness and efficiency. At higher speeds, power transmission is mixed with mechanical gears. At the highest speed, the mechanical portion of the transmission does most of the work in direct-drive mode, along with a lock up torque converter.
Several new comfort features will boost operator productivity. A new rearview, wide-angle camera provides live video to a color monitor in the cab. The camera option nearly eliminates blind spots and is ideal for operating around other machines or workers.
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.
‚ÄúAt a busy quarry, aggregate pit or construction jobsite, it‚Äôs important to have excellent visibility to all corners of the vehicle,‚ÄĚ O‚ÄôBrien said. ‚ÄúThe Case F Series wheel loaders offer better rear visibility than any competitor in the market and a panoramic view to the front and sides to increase operator confidence and productivity.‚ÄĚ
As in previous models, the Case F Series wheel loaders include an advanced instrument cluster to enable operators to adjust various functions without relying on a service technician.
The award-winning Case joystick steering also is offered with these new models. Case lets operators switch between the joystick for fast-cycle, operator-spotted tight truck loading or steering wheel for longer cycles and load-and-carry tasks.
Case optimized the standard Z-bar linkage for higher hydraulic flows. Upgraded axles include a standard axle-cooling system, and optional hydraulically-locking front differential to adapt to duties in heavy construction applications.
In addition to the Z-bar loader, Case offers XR extended-reach models for the 1021F and 1121F wheel loaders. The extended-reach option adds 21 in (533 mm) of hinge pin height to the 1021F, and 15 in (381 mm) to the 1121F.
The 1021F and 1121F wheel loaders feature longer wheel bases and a lower center of gravity. Case also reduced the overall height for easier highway transport.
The new Case 1021F and 1121F wheel loaders offer the same service access and maintainability that Case builds into all its products. These features include an easy flip-up hood, environmentally safe fluid drains, sight gauges and grouped, ground-level service checkpoints.
