First look at Isuzu’s FYX 10 x 4 model

As overall leader in the Australian truck market, Isuzu have a truck for just about every job in the Australian trucking industry, apart from extreme heavy-duty applications. Their range goes from the smallest 4.5-tonne GVM delivery truck to a 530-hp B-double prime mover with very little missing in between. However, there has been one very clear gap in the range for a considerable amount of time – and that was for a twin steer rigid suitable for work such as concrete agitator, garbage front loader, or hook lift.

The problem for Isuzu, as it is for the competition, is the requirement in Australia for a load sharing suspension on a twin steer axle to achieve GVM allowances of up to 11 tonnes per front axle. No other jurisdiction in the world specifies this kind of system as a requirement to achieve maximum GVM. As a result, manufacturers around the world have not been actively developing effective load sharing systems that comply with the Australian rules. Such systems do exist, but as an aid to truck stability and improved handling.

There is no requirement for load sharing in the Japanese domestic market and, as such, Japanese manufacturers have not invested a lot of development dollars in creating a special front suspension purely for the Australian truck market. It has been a combination of a lot of hard work on the part of Isuzu here in Australia and the importance Isuzu in Japan placed upon their Australian arm with the number one position in the truck market, which has brought about the development by Isuzu in Japan of a load sharing suspension specifically designed for our market.

“These trucks have been on our wish list for a long, long time,” Isuzu Chief Operating Officer Phil Taylor says. “The main hold up was that we wanted to get the spec just right for the Australian market. Although we have twin steers available in other global markets, they do not have load-sharing suspension. Not having one available has stopped us from competing in markets, which are now growing. With the launch of the FY range we see a lot more opportunities in the heavy duty market for us.”

The FYX 10 x 4 model simply uses the existing 8 x 4 chassis with an additional lifting tag axle fitted behind the two drive axles. The basic chassis design is able to handle the extra mass, as the individual axle weights on a 10 x 4 are actually lower than on the corresponding 8 x 4. Isuzu simply order up an 8 x 4 with a slightly longer wheelbase from Japan and the additional axle is fitted here in Australia as and when required by concrete agitator customers.
