25 years, 50,000 hours, 0 failures, and 3 simple figures are enough to prove that Allison Transmission is not a machine that can work in the harshest conditions in the world. In the unique environment of Australian outback mining areas, Two tough automatic transmissions mounted on the Steiger Tiger tractors have shown shocking performance after more than 25 years of operation.

The Australian mainland is one of the harshest areas of the Earth's natural environment. Summer heat, fine dust, rough terrain and arid deserts all combine to form an environment that poses a serious threat to the operation of machinery.

In Mildura (it is located 1,100 km southwest of Sydney, 600 km north-west of Melbourne) in the desert north of the city, bushes grow. In this typical Australian outback Arumpo Bentonite Mine, two are equipped with Allison 6000 series. Steiger Tiger tractors for gearboxes have been working efficiently and reliably for more than 20 years. They have been operating for 50,000 hours and have never failed or shut down.

The soil layer of mottled soil contains a large amount of layered aluminum silicate. Aluminum silicate is highly absorbent and widely used in the cement, binder, pottery and cat litter industries; at the same time, it is also used as a binder in the tail end of iron and steel industry, ceramic and ceramic glazes and rocket engine nozzles. Fireworks. Colin Porter, a transportation contractor in the mining area, was responsible for transporting fine, high-absorbing ore from the mining area to the refinery in the suburbs of Mildura (Australia). He believed that the Allison transmission was successful in the mining area. A key factor; he praised the incredible reliability, ideal traction, and superior performance demonstrated by Allison Transmission in this harsh environment.

Porter said: “In the past 25 years, only one inspection of the two Steiger Tiger tractors demonstrated how amazing the durability and reliability of this gearbox are.”

In the Allenpo mining area, working conditions are even worse. This area can only be operated between the local summer from October to April, when the ambient temperature is close to 50 degrees Celsius and the internal parts of the machine often reach 70 degrees.

“This desert will become very hot, and our tractors must work hard on this soft, powdery soil.” Potter added: “We have selected ore from open-pit mines, and then Tiled in a drying pool, if a machine can work smoothly under such conditions, it will be able to perform its job anywhere."

“The Allison transmission proved it was perfectly suited to the job we assigned. They are very suitable for this job because no matter how hard we go, we can choose the right gear and keep the speed; this work is very difficult for machinery. Yes, but the Allison transmission did not disappoint us. No matter how hot and hard it was, the machines were always working, Potter said.

The two Steiger Tiger tractors with Allison transmissions were used equipment, which had been in operation for nearly 20,000 hours; since then, both vehicles have been running for 30,000 hours and have only reached the total running time. A preventive maintenance was performed at 40,000 hours.

Anywhere in the world... under challenging conditions

Allison provides global automakers and end-users with a wide range of commercial fully automatic transmissions that can operate under the harshest conditions, whether on the BELAZ dump truck in Siberia or the Volvo heavy-duty truck in Sweden. The Allison transmissions are reliable, durable and efficient on the Tucker snowmobiles in Sweden's South Pole.
