Caterpillar’s new 988K XE is its first wheel loader offered with a high-efficiency electric drive system. It features switched reluctance (SR) technology and has undergone four years of field testing. The C18 Acert engine, mechanical dropbox, driveline, and axles from the standard 988K are carried over in the electric drive loader. The electric drive unit is said to increase efficiency by 25 percent overall and up to 49 percent in face-loading applications, compared to the 988K. At the same time, Cat production studies report it delivers up to 10-percent higher productivity in load-and-carry applications. A range of buckets, from 6.2- to 17-cubic yards, is available. Rated standard payload is 12.5 tons when working with face material and 16 tons with loose material. The loader is a three-pass match with the 42.6-ton Cat 770G and a four-pass match with the 51-ton Cat 772.
