Cat CT630S & CT630SC

In May, Cat Trucks added two new, B-double-rated prime movers to its portfolio. The CT630S and CT630SC are based on the first Cat range unveiled in 2010, but feature a cab that has been raised 50 mm and moved forward approximately 250 mm to fit into the 26-metre, 34-pallet B-double framework.

Apart from those basic dimensional changes to fit into the B-double envelope, the shortened hood and raised cab of the day cab ‘S’ and sleeper cab ‘SC’ are supposed to provide several additional benefits. According to Cat, these include enhanced manoeuvrability, an improved line of sight from the driver’s seat and a smoother passage of air underneath the cab to further complement Cat’s high standards of cooling efficiency.

As with all Cat CT630 models, the ‘S’ and ‘SC’ have a gross combination mass rating of 90 tonnes, allowing them to handle B-triple and even road train work in addition to their primary B-double role.

Even though both CT630S and CT630SC are based on past Cat models, they were specifically developed for Australia’s highly contested B-double market.
