Long-haul luxury for these two Cats

Caterpillar launches two new models to suit Australian roads and make big journeys more comfortable.

Caterpillar Trucks reinforced its long-term commitment to becoming a leading player in truck manufacturing last month when it revealed two markedly different heavy-duty trucks but with the same application in mind.

The company unveiled a luxurious version of its CT630, the CT630LS, and a short-bonnet prime mover also based on the CT630 platform, the CT630S. Both models are expected to be available here by the end of this year.

The CT630LS is the company's first foray into the high end of the heavy-duty segment, while the CT630S is a direct result of the company's market research, which indicated a need for a short-nose truck with either a bumper to back of cab (BBC) measurement of 112 inches (285 centimetres) for a day cab, or 138 inches (350 centimetres) for a sleeper cab. The luxurious CT630LS with a 56-inch (142-centimetre) sleeper cab has a BBC of 168 inches (427 centimetres).

Both trucks have a gross combination mass of 90 tonnes and both are powered by Cat's C15, rated up to 550hp (410kW) and 1850ft/lb (2508Nm) of torque, making them a walk-up start for B-double applications.

The CT630LS has a fuel capacity of 1510 litres, while the CT630S is good for 980 litres. Caterpillar's C15 engine uses dual horizontal diesel particulate filters (DPFs) to eliminate the need for exhaust gas recirculation (EGR) or selective catalytic reduction (SCR) for emissions compliance.

The company says by using dual DPFs, fuel efficiency remains basically the same as in previous ADR 80/02 emissions trucks.

The general manager for sales and marketing of Cat Trucks Australia, Jeff Tyzack, says the CT630LS will be an exciting option for customers, particularly those engaged in interstate transport.

''Drivers can now drive across [the] country in one stylish, luxury vehicle, secure in the knowledge that they will be fully looked after and supported by the Cat dealer network,'' he says.

The general manager of Cat Trucks Australia, Bill Fulton, says the CT630S has been developed for the Australian market and is designed to meet the demands of the Australian road environment.

The CT630LS offers a spacious cabin, enabling the driver to access all areas standing up. There is a large 2040mm x 900mm mattress in the CT630LS, while the CT630S sleeper cab provides a 1850mm x 660mm mattress.

The CT630LS has split-system reverse-cycle airconditioning that offers separate temperature controls in the driver and sleeper areas.

The stylish cabs are a product of Cat Trucks's joint-venture partner Navistar and meet the stringent European cab-strength requirements. The cabs are mounted on strut-type suspension, which provides improved stability and comfort. Side vent windows are standard on both models.

Notwithstanding its spacious dimensions, Cat says the CT630LS is highly aerodynamic for a high-rise sleeper, despite its 4024-millimetre height with its aero roof and 3760-millimetre height without. Cat says its integrated, aerodynamic cab design provides line-haul and roadtrain customers with improved fuel efficiency.

A robust chassis frame measures 260mm x 92mm x 9.5mm, with an insert over the tandem axle and an upper frame tie for the high-rise sleeper.

Both models come equipped with the latest Meritor RT46-160 rear axles on Hendrickson Primaax PAX 460 air suspension fitted with traction control, with a differential lock standard on the RR axle, as are alloy hubs, while differential locks on both axles are offered as an option.

An Eaton-sourced manual transmission comes standard and, should you prefer not to shift your way through an 18-speed gearbox, there is an optional Eaton UltraShift Plus transmission, again on both models.

Aerodynamic chrome mirrors come standard with electric operation and heating. LED headlights, which are standard, improve vision and have a longer life.

Also standard are anti-lock brakes with an ABS connector for similarly equipped trailers. Both the new vehicles come with the standard four-year, 800,000-kilometre coverage for the driveline.
