Allison Transmission and Volvo Construction Equipment meet again after 37 years – new Allison 6630 ORS for 55-ton Volvo A60H

Volvo Construction Equipment has been producing articulated haulers for 50 years and Allison Transmission has a 70-year history of manufacturing fully automatic transmissions. The two market leaders first connected in 1979 in the 5350 model articulated hauler, and now, 37 years later, it's time to meet again

MUNICH The new 55-ton Volvo A60H, the largest articulated hauler Volvo Construction Equipment builds, will be launched at Bauma 2016. It is equipped with Allison's new 6630 ORS fully automatic transmission that is tailored to fit the modern high-power Volvo engine.

The new 6630ORS model is an evolution in the Allison 6000 SeriesTMrange of transmissions, offering further increased durability and performance. It contains a new internal damper and updated torque converter turbine with improved vane geometry and anodized surface treatment for increased durability. Furthermore, a new heavy duty retarder rotor is now an available option.

The Volvo A60H also benefits from modifications to the transmission’s low and reverse planetary gear assemblies. Increased oil flow lubrication delivers extended product life in vocations like mining that demand high torque or prolonged reverse range operations. This means the new Allison 6630 ORS transmission supports low total cost of ownership and high profitability in Volvo‘s articulated haulers.

Renowned worldwide for working hard over a long service life with minimum downtime and high productivity, Allison transmissions are designed and engineered to perform under pressure. In the most demanding environment, over the toughest terrain – Allison Automatics are designed and manufactured to yield higher performance with lower maintenance requirements, achieving faster work cycles and extended service intervals.
