LAS VEGAS (March 22, 2011) – 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.
“Case is taking the industry lead with the new F Series wheel loaders,” said Tim O’Brien, Case marketing manager. “We’ve launched these Case wheel loaders with new highly-efficient, high-horsepower engines and advanced SCR emissions technology. So the machines will respond faster—and you’ll save fuel.”
O’Brien 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. “This 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,” 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.
“With the SCR technology, Case is making what was already the industry’s most fuel-efficient line of wheel loaders even more fuel efficient,” explained O’Brien. “At the same time, the F Series engines ‘breathe freer’ than engines with a cooled exhaust gas recirculation (CEGR) solution. This lets wheel loaders respond to the throttle faster.” 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—Economy, Standard, Max and Auto—to 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’s 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.
“At a busy quarry, aggregate pit or construction jobsite, it’s important to have excellent visibility to all corners of the vehicle,” O’Brien said. “The 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.”
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.
TORRANCE, Calif. (March 22, 2011) – Kubota Construction Equipment introduced several new equipment models at ConExpo-Con/Agg in Las Vegas last month.
“Kubota keeps a continuous pulse on the construction market. We listen to what operators need to make their jobs more efficient, and then we deliver in classic, dependable Kubota style,” says Keith Rohrbacker, construction equipment product manager for Kubota. “Our construction equipment line is all about meeting and exceeding the expectations of our customers and providing precisely what matters most.”
“For example, with the new Kubota compact track loaders we responded to market demand and introduced the SVL75 and SVL90 with best-in-class bucket breakout-force and exceptional lifting capacity. This year, we will introduce a cab model to the compact track loader line – all based on what is important to our customers,” added Rohrbacker.
Kubota SVL75-SVL90 Compact Track Loaders – The new compact track loaders are fully Kubota designed, engineered and manufactured. The machines offer bucket breakout force and lifting capacity. The 74.3-gross horsepower SVL75 boasts a 6,204- pound bucket breakout-force and a 4,881-pound lifting capacity.

The R420S produces a maximum bucket breakout force of 6,550 pounds, while the R520S breakout force is rated at 7,425 pounds. Kubota’s load sensing transmission enables efficient load handling by automatically adjusting speed and torque as load conditions vary.
The launch of its new BL61B* and BL71B* sees Volvo Construction Equipment thoroughly redesign its backhoe loader range – offering improved performance, usability and a modern appearance.
Both machines have a new curvier, stylized look, as well as a roomier CareCab. With an operating weight that ranges from 7.1 t to 9.8 t, and gross power of 64 kW to 74.9 kW, the BL61B and BL71B were designed and built with power, strength, long life and cost saving efficiency in mind.
Loader and boom
The one piece chassis, loader arm and excavator boom are all made from high quality steel and robotically welded, giving precise, constant weld runs for structural integrity. The loader arm has a box-welded design and is reinforced with a cross tube. The larger excavator boom has a narrow, tall arch design that is inherently strong, and uses a closed box-welded approach with fewer components and welds, for durability and performance. The boom allows excellent visibility into the trench, as well as enabling closer proximity to the truck for loading. The cast iron kingpost offers flexibility of movement and swing.
Control in your hands
Compared to previous models the new BL61B and BL71B feature new controls. The machines are fitted with two floor mounted ergonomic levers that give the optimum grip for the operators hand movements when operating the excavator. The right lever is fitted with a horn for safety, and the left lever can have an optional fingertip button. This button controls the two-way auxiliary hydraulic line required when using double acting excavator attachments. The BL71B’s front loader is fitted with a single lever joystick for operating loader arm and bucket movements, multipurpose bucket opening and closing and also Forward, Reverse and Neutral transmission functions.
Fitted with either 18 inch or 20 inch front tires, these machines have a small turning circle and are extremely maneuverable, as well as easier to position on site. Helped by a new cast bucket linkage design, the bucket can rotate 205o – allowing vertical digging in all positions without repositioning the machine. Stability is improved by new rectangular stabilizer feet that have 30% more ground surface contact over previous models. The stabilizers are independently controlled, the pads are rotatable and easy replaced when worn.
Delivering the power
The BL61B and BL71B both feature Volvo’s latest D5D four cylinder 4.8 litre engines, with direct injection and turbo charging. These high torque, fuel efficient engines meet the requirements of the Stage IIIA emissions legislation. The torque converter on these machines is one of the largest in the industry and has excellent peak torque and torque rise. A differential lock on the rear axle is engaged via a foot switch on the side of the brake pedal and provides maximum rear wheel grip over slippery surfaces.
Both the loader and excavator benefit from flow sharing hydraulics that enable multi-functioning. BL71B features load sensing hydraulics that constantly adapt to the needs of the job in hand. With oil delivery that matches the required force, there is always the speed and power required for all hydraulic functions. In applications such as load and carry, where speed is important, the system efficiently delivers the required flow.
The redesigned Volvo CareCab is now better than ever. Boasting 15% more space than before, the room between the operator’s seat and the left side of the cab has been increased, as has space around the excavator mechanical controls or pilots towers, making the position change between loader and excavator easier and more convenient. There is also a larger area to store personal items. The seat, steering controls and instruments are all designed to lower fatigue and keep operators alert and in control. Comfort can be increased further with multi-adjustable steering column and high performance heating & cooling systems. A 30% increase in glass area combined with narrow pillars and a sloping hood bonnet design allow all round visibility when working. Visibility is helped outside the cab, by adjustable standard-fit halogen work lights, and internally by a large cab dome light for safer entry and exit of the cab.
Both ends of the machine can be equipped with versatile, easy-to-use attachments and quick couplers. B-Series backhoes can be configured with general or multi-purpose loader buckets, pallet forks, hydraulic thumb, standard and heavy duty excavator buckets, hydraulic breaker attachments – a vast range of solutions. Bucket loader capacities range up to 1.0 m3 and the backhoe excavator buckets have a maximum volume of 0.33 m3.
Service and daily maintenance is made easy with the B-Series, with a one piece lifting hood and filters/service points all grouped together at ground level. Fewer greasing points and long greasing intervals also help to increase uptime. A tilting oil cooler in front of the radiator makes cleaning both the cooler and the radiator quick and easy.

The rollers can be tailored to local conditions, including engine power, operator’s platform, and air conditioning. Each Dynapac CC tandem asphalt roller is equipped with the DCA-A Compaction Analyzer which monitors and records key parameters via a GPS-assisted, graphic, real-time display of temperature and number of passes.
The CC224HF, CC234HF, CC324HF, CC334HF, CC384HF, CC424HF, CC524HF, and CC624HF are dual-drum models. Combi models—CC224CHF, CC234CHF, CC324CHF, CC334CHF, CC384CHF, CC424CHF, CC524CHF, and CC624CHF feature a drum roller and rear set of wheels.
Dynapac CC rollers are engineered to compact any type of asphalt mix. They feature high frequency/low amplitude for thin layers and high amplitude for thick layers. The articulated tandem rollers are powered by a Cummins QSB 4.5 water-cooled turbo-diesel engine with after cooler. The rated power is 125 hp at 2200 rpm for the CC424HF, and 152hp for the larger CC524HF and CC624HF models. The new machines have operating masses ranging from 11.6 tons to 13.9 tons. The weight is split evenly between the front and rear drum modules.
The tandem asphalt rollers include features such as soft starting and stopping, which is designed to prevent unevenness and cracking in the asphalt layers. In a panic situation, the machine will drop out of the soft mode and immediately brake.
The machines feature a double-pump vibration system, which eliminates the need for a vibration valve. This feature is designed to make the system more efficient, aid in the servicing, and reduce fuel consumption. Fuel consumption is expected to be further reduced because there are fewer number of hydraulic hose fittings, proportional control of cooler fan speed used for engine coolant and hydraulic oil temperatures, and automatic diesel engine idling after 10 seconds in neutral.
Dynapac CostCtrl tool for all of the models, is designed to help roller owners estimate total cost of ownership by controlling fuel, investment, maintenance, wear, and operator cost parameters.
