In 1985, Caterpillar launched its first backhoe loader model, the Cat 416A, a definitive interpretation of a multitasked workhorse and the forerunner of a ground breaking series.

In fact, today there are still examples in South Africa of A-Series and 1989 era B-Series units in daily service.

Since then, the Cat backhoe’s distinctive features have evolved with each successive model upgrade; recent examples being the E-Series launched globally in 2006, and E2 mid-range update rolled out in 2009.

Now in 2012, the F-Series takes over the reins as the next class leader, launching across Southern Africa from the third quarter of 2012. Side-shift model introductions focus on popular Cat 416, 422 and 428 variants within the new line-up, all of which are manufactured at Caterpillar’s Leicester factory in England. Centre pivot models are available on request.

“Together with significant body design enhancements, F-Series machines across the range come to the market with greater lift capacity, increased dump height, more bucket breakout force and increased backhoe control,” explains Barloworld Equipment product application specialist, Desigen Naicker.

The loader’s arms have been redesigned and are now fully parallel (rather than divergent), improving stability and strength, as well as facilitating better bucket material retention. New one-piece counterweights further improve stability.

Safety is a key design feature on all Cat machines, as is an emphasis on ease of maintenance. On the F-Series, a new battery isolator enables the operator to safely isolate the machine’s electrical power, which also increases machine security.

Oil checks, fills and other service items are now accessible from the left-hand side of the machine at ground level, while the front axle has no greasing points. A larger, 160 ℓ non-metallic fuel tank in turn extends refill intervals.

Across the range, power on the go is supplied via a new Tier II Cat 3054 engine in various KW output configurations, depending on the model. The Cat 422F, for example, is powered by a Cat 3054C 56.5 kW unit, with the larger 428F backhoe loader driven by a Cat 3054CT engine that generates 68.5 kW. Both units reach a 40 kph maximum roading speed. Boosted brakes improve machine braking to all four wheels.

Cat 416F and 428Fs sold in Southern Africa feature selectable two-wheel and four-wheel drive, activated from inside the cab, while the Cat 422F is supplied with a fixed two-wheel drive mode. An electrically operated differential lock is fitted as standard on all models.

“The F-Series takes backhoe loader performance to the next class with these and other design innovations, while retaining all the field-proven elements that have evolved since the A-Series debuted in 1985,” says Naicker.

These include powerful, load-sensing, closed centre hydraulics; Caterpillar’s four speed Power Shuttle transmission, for on-the-go directional and range shifting; the signature Cat excavator-style boom; and best-in-class 205 degree bucket rotation, making it easier for the operator to dig square-end and flat bottom trenches.

“Combined with latest generation features, new F-Series machines offer a formidable performance package, which is certain to lift the game on building and construction sites across Southern Africa,” concludes Naicker.
