EFFICIENT AND SAFE OPERATION There are four working modes – max, economy, normal and auto – which allow the operator to maximise productivity and reduce fuel consumption
Earthmoving equipment supplier CASE Construction Equipment South Africa’s range of full-size F-series wheel loaders has advanced features for faster operation, higher productivity, lower fuel consumption and improved safety on site.
“The F-series wheel loaders, with reduced emissions, also offer increased power ratings, an additional lifting capacity and greater break-out force,” says CASE Construction Equipment South Africa MD Ross Collard.
CASE Construction Equipment South Africa is a subsidiary of Invicta Holdings, Capital Equipment Group.
“Four models in the F-series are available locally – 621F, 821F, 921F and 1021F machines – each designed for efficient and safe operation in arduous applications in diverse industries, including construction, quarrying, mining and waste handling,” Collard explains.
The robust F-series, with selective catalytic reduction technology to meet the latest Tier 4 emissions standards, offers increased power ratings and fuel savings of up to 10%. Fuel economy is increased further with the standard engine shutdown feature, which limits engine idle time.
He states that Case 621F, 821F and 921F models have a 6.7 ℓ engine and the 1021F has an 8.7 ℓ engine, all with high horse power and torque ratings to deliver the exact power required for each task.
“The standard four-speed transmission has a lock-up torque converter for improved acceleration and safe hill climbing. This transmission provides continuous short cycles for fast performance and high productivity. The POWERINCH declutching feature ensures accuracy and control when operating in tight settings, especially during truck loading,” he adds.
A common-rail electronically-controlled certified diesel engine gives the operator four work modes to choose from (economy, standard, auto 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 reduced overall emissions.
CASE F-series wheel loaders maintain precise control of oil temperature in the axles to ensure dependable operation. The cooling module is now fitted higher in the chassis for improved performance and reduced running costs. This system, with an auto or manual reverse fan that clears dust and debris from the radiator fin, maintains temperatures at an optimum level for extended component life.
He notes that an open differential on the front and rear axles also prevents overheating and a differential lock on the front axles provides effective grip control on any surface, particularly on soft soil, where greater resistance is needed.
Special solid, foam-filled tyres and tyre chains can be fitted to cope with demanding applications, for example, the handling of scrapped materials like iron, wood, glass, plastics and civil organic waste.
The low vibration cab offers improved operator comfort and optimum safety. Advanced sound insulation materials and the electronic injection engine ensure reduced noise levels.
A low-effort, single-lever loader control joy stick incorporates a quick shuttle switch for faster, more precise operations. 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. All controls have been designed to be highly responsive to commands and digital displays enable clear reading in all lighting conditions.
For optimum safety and durability, the cabs of these wheel loaders are reinforced and are rollover protection structure certified, ensuring operator protection against roll-over. These machines are also available with extended reach linkage for a greater dump height and versatility.
“Engine diagnostics are done inside the cab, enabling quicker detection of service needs. Maintenance is made easy with a full raise-up hood, environmentally-safe fluid drains, sight gauges and grouped, ground-level checkpoints,” he says.
CASE construction equipment, which includes backhoe loaders, compact track loaders, excavators, telehandlers and skid steers, is supported by CASE Construction Equipment South Africa’s national technical advisory, maintenance and spare parts service.
