New F-Series machines offer increased productivity and a 10% reduction in fuel consumption
CASE Construction Equipment have introduced three new F-Series wheel loaders – the 20-tonne 921F, 17-tonne 821F and the 14-tonne 721F – to European customers. The loaders are said offer faster acceleration, reduced cycle times, higher travel speeds and increased productivity, yet boast up to a 10% reduction in fuel consumption.
The F-Series loaders are powered by efficient Tier 4 interim diesel engines, with improved programmable power modes. An optional five-speed transmission further boosts fuel savings, while improvements to the cab environment reduce operator fatigue, increasing productivity.
All three F-Series loaders employ a 6.7-litre Tier 4 interim certified engine. Offering increased horsepower (225hp, 206hp and 179hp respectively) and torque output, the engines use proven selective catalytic reduction (SCR) technology to meet emissions regulations.
Case’s four-mode programmable power control – offering Economy, Standard, Auto and Max settings – has been upgraded on the F-Series machines, providing operators with increased flexibility when matching the engine output for each task. In addition, an optional five-speed transmission with a lock-up torque converter, open differential axles and advanced system programming, contributes to the reduction in fuel consumption.
Limited-slip differentials are standard in both front and rear axles, providing effective traction in all ground conditions. The standard four-speed transmission with manual kick-down setting allows maximum traction and bucket breakout during digging and loading operations, while between loads a dual-mode shutdown feature allows the operator to set and limit the time that the machine can idle, in 5min increments.
With increased power and improved tractability, a major F-Series productivity boost comes from increased bucket capacities. The 921F takes Case into a new size class with its 3.6 cubic metre standard bucket. With greater tipping load weight and increased bucket breakout force, the 921F has been designed primarily for aggregate stockpiling and high-production truck loading duties. The standard capacity for the two smaller machines is 2.5 cubic metres for the 721F and 3.25 cubic metres for the 821F.
The F-Series cab offers an unobstructed view to both edges of the bucket or attachment, while a wide window and the sloping engine cover provide excellent visibility to the rear. A new wide-angle rear-view camera with an adjustable colour monitor is available on all F-Series loaders, eliminating blind spots for the operator.
The standard advanced instrument cluster allows operators to adjust various machine functions from within the cab without relying on a service technician. Ergonomically placed controls and a new heated cloth seat with seven adjustment modes complete the cab improvements.
Case are also offering a range of attachments for the F-Series loaders to broaden their appeal in different market sectors. All three machines can be ordered with a standard Z-bar loader linkage or an XR long-reach arm configuration. The 721F can also be configured with XT parallel lift arms for use as a tool carrier. Pallet forks, jib booms, sweepers and a full range of buckets are also available, along with weigh-loading systems for production applications.
