For almost a decade Allison has been specified as the transmission of choice for the Hanson fleet of concrete agitators across Australia with more than 500 trucks fitted with Allison automatic transmissions mated to Cummins power plants. Hanson unified its purchasing requirements around 2003 with a single national specification. Allison became the cornerstone of the companys driveline choice for all of its concrete agitators. According to Hansons national fleet logistics manager,Peter Black,Allison Transmissions have been a logical and rational choice given their track record for reliability and performance over many years. Automatic transmissions are really the only choice for our operations. They make our drivers jobs that much easier and safer. Given all the things that drivers have to look out for,we dont want them to have the extra task of changing gears, said Peter Black. Allison transmissions have proven themselves over many years. With the back up and service support place through its extensive distributor and dealer network,they are a tried and trusted choice for our fleet of concrete trucks, he said. Prior to implementing a national purchasing regime,buying decisions were made individually by state offices which meant we had a mixed fleet. Since introducing a consistent national policy we have been able to maximise efficiency by using components that are the most efficient and reliable, he added. Minimising downtime is very important to us. The performance of Allison over many years means we really dont have a reason to move away from them. They are a known entity with great service back up and reliability, he said. Hanson has an annual vehicle replacement program. New trucks are put into service in metropolitan operations in major cities across the country. After a number of years they move to country operations in rural areas for the remainder of their time on the Hanson fleet.
