Caterpillar believes that its newly-designed 966K XE wheel loader will take centre stage at the Intermat expo, with the machine able to deliver energy savings of 25% over the previous model.
With an operating weight of 24,189kg, the wheel loader has been engineered with an integrated Cat continuously variable transmission (CVT) system.
The 966K XE is powered by a Cat C9.3 ACERT diesel engine, delivering a peak net horsepower rating of 220kW.
It meets EU Stage IIIB emissions standards, with high-pressure common rail injection system for a more efficient burn.
The emissions module incorporates a diesel oxidation catalyst, a diesel particulate filter, and a regeneration system.
A hydraulic pump and motor (variator unit) allow for a smooth and continuous gear ratio change between engine speed and machine speed says the manufacturer.
“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,” says Caterpillar.
Also boosting efficiency is a system to recover machine momentum during deceleration as free energy, used to power implements or the cooling fan.
“The engine runs at the most efficient speeds to reduce fuel consumption, which could lead to extended engine life. Furthermore, integrated retarding and modulated torque control could also result in increased tire and brake life,” says Caterpillar.
The 966K XE will be initially available in Belgium, France, Germany, Italy, Netherlands and the United Kingdom in the fourth quarter of this year.
