“The 966K XE has been engineered to deliver superior efficiency by utilising an integrated Cat continuously variable transmission system,” says the company.
The 966K XE, which is being tested at various sites throughout Europe, will be initially available in Belgium, France, Germany, Italy, Netherlandsand the UK in the fourth quarter of 2012.
A hydraulic pump and motor (variator unit) on the model allows for a smooth and continuous gear ratio change between engine speed and machine speed. The variator provides this ratio flexibility while greatly reducing the heat load generated by the drive train when the machine is digging, pushing and climbing under heavy load. The continuously variable gear ratio of the variator also enables the engine to run at a more efficient operating range independent of machine ground speed.
Power is transmitted through the variator unit (versatile gear ratio) as well as a parallel mechanical gear path (highest efficiency). Power through the variator and mechanical paths are combined through a series of planetary gear sets in order to maximise the transmission efficiency over a wide range of operating conditions.
The 966K XE is powered by a Cat C9.3 ACERT diesel engine, delivering a peak net horsepower rating of 220kW.
Meeting the European Union Stage IIIB emissions standards, the engine incorporates a high-pressure common rail injection system for a clean, efficient burn.
Developed especially for production loading for both 966K and 966K XE, Performance Series buckets are standard.
