Cat launches electric-drive wheeled loader

Caterpillar has launched its first wheeled loader with a high-efficiency electric drive system.

The Cat 988K XE Wheel Loader is designed to offers higher fuel efficiency and a lower total cost of ownership. The company said that the new electric-drive loader delivers 25% greater overall efficiency and up to 10% more productivity in load-and-carry applications than the 988K loader.

It is recommended by the company for demanding sites where fuel efficiency makes a difference in the machine’s total cost of operation.

The new loader features switched reluctance (SR) technology and leverages more than 15 years of Cat electric drive experience and more than four years of testing. The C18 Acert engine, mechanical dropbox, driveline and axles from the 988K remain in the electric-drive machine.

The new Cat 988K XE loader offers a range of bucket capacities from 6.2 to 17 cubic yards. Rated standard and high-lift payload for the loader reaches 12.5 tons when working with face material and 16 tons with loose material.

The standard 988K XE wheeled loader is performance-matched to offer three-pass loading of the 42.6-ton Cat 770G andfour-pass loading of the 51-ton Cat 772. Its high-lift configuration delivers five-pass loading of the 61-ton Cat 773G and six-pass loading of the 70.5-ton Cat 775G.

Cat electric drive technology found in the new 988K XE is said by the company to lower overall maintenance costs, while increasing engine life expectancy. It offers extended oil change intervals of 2,000 hours and uses 40% less power-train oil. Additionally, the efficient electric drive design is claimed to increase engine life by up to 3,500 hours, extending the time between power-train rebuilds.

Slight changes inside the cab of the new 988K XE provide operators with the familiar functions and feel of the 988K. The new loader offers a single speed range, so the machine operates without the need for gear shifting. New virtual gears help to control machine ground speed and deliver smooth direction shifts.

The standard Cat Product Link offers remote data monitoring, so key personnel can stay informed of critical machine operating data.  Other features include Cat Production Measurement (CPM), which brings payload weighing to the cab.
