The new Cat® 988K XE is the first wheel loader offered by Caterpillar with a high-efficiency electric drive system. This new large wheel loader joins the industry leader 988K and the recently launched 986K wheel loaders to provide customers with the most cost-effective loader for each application. Delivering high-production in all loading applications, the 988K XE is recommended for demanding job 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 4 years of stringent testing in a range of applications for proven reliability in the field. The field proven and tested C18 ACERT™ engine, mechanical dropbox, driveline and axles from the 988K remain in the electric drive machine for consistent, trouble-free operation.

The new 988K XE increases efficiency by 25% overall and by up to 49% in face-loading applications, as compared to the 988K. This reduces costs and helps operations reduce greenhouse gas emissions and carbon footprint. Caterpillar production studies report the new loader delivers up to 10% higher productivity in load-and-carry applications.

The new Cat 988K XE loader offers a range of bucket capacities from 4.7-13 m3. Rated standard and high lift payload for the loader reaches 11.3 tonnes when working with face material and 14.5 tonnes with loose material. Advansys™ Series Ground Engaging Tools (GET) protect bucket components and reduce operating costs, so operations can get the most out of machine performance.

The standard 988K XE wheel loader is performance matched to offer efficient 3-pass loading of the 38.6-tonne Cat 770G and 4-pass loading of the 46.3-tonne Cat 772. Its high-lift configuration delivers 5-pass loading of the 55.3-tonne Cat 773G and 6-pass loading of the 64-tonne Cat 775G.

Cat electric drive technology found in the new 988K XE lowers overall maintenance costs, while increasing engine life expectancy. Offering extended oil change intervals of 2,000 hours, the electric drive wheel loader uses 40% less powertrain oil.

The durable SR drive motor, generator and inverter are built to last through the second engine life with minimum maintenance. Additionally, the efficient electric drive design increases engine life by up to 3,500 hours, extending time between powertrain rebuilds.

Caterpillar offers customers world-class service training material, backed by industry-leading customer support from the extensive Cat dealer network. Remanufactured drive motors, generators and inverters will also be available to reduce rebuild cost.

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

As customers have come to expect from the 988K, operators safely access via left- or right-hand stairs built at a reduced 45-degree angle and maintain three points of contact at all times. The STIC steer armrest easily folds up, allowing the operator to quickly enter the cab. Isolation cab mounts and an air-suspension seat reduce vibration transmitted to the operator for increased comfort, while the enclosed pressurised structure reduces operator sound levels. The automatic, in-cab temperature control system maintains operator comfort even in extreme temperatures.
