CASE 821E wheel loader
CSE Equipment Company, exclusive distributors of the Case range of construction equipment, has extended its product portfolio to include the new high production 821E wheel loader, one of the largest models in the Case range.
"This new wheel loader, which has the highest performance rating of any wheel loader in its class, enhances the power efficiency of Tier III engine technology, with advanced hydraulic and transmission systems,” says Rod Watson divisional director of CSE Equipment’s construction division. “This environmentally friendly engine technology offers 11% more power, with lower fuel consumption, than previous models and this means an overall reduction in emissions.”
The 821E wheel loader, with an operating weight of 17 166 kg, an engine rating of 159 kW and bucket capacity of up to 3,40m³, has enhanced power and capacity for arduous applications in construction, quarrying, mining and related industries.
A new common rail electronically controlled certified diesel engine gives the operator four work modes to choose from and three power and torque levels (economy, standard and maximum power) for optimum efficiency in any application. Benefits include better use of available power, lower fuel consumption, reduced wear on the engine and drive line, lower noise levels and less overall emissions.
This new machine has advanced features that include a torque sensing autoshift transmission that boosts productivity. The operator chooses the working mode from within the cab, or the autopower facility can be selected, in which case the power curve is automatically matched to each application. For maximum performance, demand is constantly monitored with engine output and torque is continually adjusted.
Rear axle oscillation of approximately 24° and a ground clearance of 416 mm, enable safe travel over rough ground conditions, with good load retention. Despite its size, this unit has an outside bucket edge turning radius of only 6 032 mm. An 80° turning angle enables rapid truck loading.
The efficient mid-mounted cooling module, with an auto-reverse fan that clears dust and debris from the radiator fin, maintains temperatures at an optimum level for extended component life. This improved cooling system significantly reduces ownership costs
The 821E wheel loader retains the proven Case Z-bar linkage, which offers superior breakout force (18 479 kg) and impressive digging characteristics (maximum lift capacity at ground is 16 959 kg). This design also gives the operator better visibility to the corners of the bucket.
Other features include a bucket capacity up to 3,4 m³ and a maximum hinge pin lift height of 4,12 m. This enables rapid loading of trucks and rail wagons.
The re-designed low vibration cab, which is longer and wider then previous models, offers improved operator comfort and optimum safety. Advanced sound insulation materials and the electronic engine ensure reduced noise levels.
Floor to ceiling glass provides excellent all-round visibility, including an unobstructed view of the front-end attachment in all positions. The operator also has clear visibility to the rear because the contoured single piece engine canopy and engine pre-cleaner are mounted in line with the exhaust stack.
A low-effort, single-lever joy stick incorporates a quick shuttle switch for faster, more precise operations. All controls have been designed to be highly responsive to commands and digital displays enable clear reading in all lighting conditions.
This new wheel loader offers reduced service times. Engine diagnostics are done inside the cab, enabling quicker detection of service needs. Maintenance-free wet disc brakes and components designed for extended service life, also contribute to faster service time.
With the cooling module centrally mounted, access to the engine is simplified and only requires the removal of a single thumbscrew. A one-piece electric lift hood opens 180° for unrestricted access. Fluid sight gauges on all reservoirs and service points are grouped together for easy daily maintenance checks that are carried out from ground level. The engine is located behind the rear axles to enable easy access to all components for routine servicing. Easily accessible fluid drains minimise the risk of spillage during fluid change.
Case construction equipment, which includes loaders, backhoe loaders, excavators and skid steers, is supported by CSE’s national technical advisory and maintenance service.
