The new 55-ton Volvo A60H, the largest articulated hauler Volvo Construction Equipment builds, was 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 Series range 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.
