New Electric Drive Cat 988k XE Wheel Loader Offers Higher Fuel Efficiency, Lower Total Cost Of Ownership


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 four 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.

Maximum Efficiency, Productivity

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

The new Cat 988K XE loader offers a range of bucket capacities from 6.2 to 17 cu. yd.(4.7 to 13 cu. m). Rated standard and high lift payload for the loader reaches 12.5 tons (11.3 tonnes) when working with face material and 16 tons (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 three-pass loading of the 42.6-ton (38.6-tonne) Cat 770G and four-pass loading of the 51-ton (46.3-tonne) Cat 772. Its high-lift configuration delivers five-pass loading of the 61-ton (55.3-tonne) Cat 773G and six-pass loading of the 70.5-ton (64-tonne) Cat 775G.

Extended Service, Lower Ownership Costs

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 percent 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.

To assist with electric drive 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.
