Caterpillar, Peoria, Illinois, has released the new Cat 988K XE, which it says is its first wheel loader with a high-efficiency electric drive system. This 988K XE wheel loader joins the 988K and the recently launched 986K wheel loaders to provide customers with the most cost-effective loader for each application, Caterpillar says. Delivering high-production in all loading applications, the 988K XE is.
The new loader, which Cat recommends for demanding job sites where fuel efficiency makes a difference in the machine’s total cost of operation, features switched reluctance (SR) technology and leverages more than 15 years of Cat electric drive experience and more than four years of testing in a range of applications for proven reliability in the field. The C18 ACERT engine, mechanical dropbox, driveline and axles from the 988K remain in the electric drive machine for consistent, trouble-free operation, according to Caterpillar.
Offering increased truck loading and load-and-carry efficiency, the 988K XE increases efficiency by 25 percent overall and by up to 49 percent in face-loading applications as compared to the 988K, the company says. This reduces costs and helps operations reduce greenhouse gas emissions and carbon footprint. Additionally, according to Caterpillar production studies, 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 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. Advansys Series Ground Engaging Tools (GET) protect bucket components and reduce operating costs, Caterpillar says.
Cat electric drive technology found in the new 988K XE lowers overall maintenance costs while increasing engine life expectancy, the manufacturer says. Offering extended oil change intervals of 2,000 hours, the electric drive wheel loader uses 40 percent less powertrain oil.
The 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 also will 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, Cat says. 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, according to the company.
The standard Cat Product Link offers remote data monitoring through VisionLink, so key personnel can stay informed of critical machine operating data. Fuel usage, payload summaries, scheduled service reminders, fault code alerts and various productivity reports are available to help improve machine management. Additionally, the onboard Vital Information Management System (VIMS) provides the operator with operating data, such as real-time fuel consumption and fuel efficiency via an interactive touch-screen display.
The Cat 988K XE loader also features technology solutions designed to increase operating efficiency and machine uptime. Cat Production Measurement (CPM) brings payload weighing to the cab, so operators can work more productively and deliver accurate loads with confidence. CPM offers advanced weighing modes, which assist with payload accuracy and increase loading cycle speed.
The Optional Tire Pressure Monitoring System (TPMS) is a fully integrated Cat feature, which enables operators to monitor tire inflation. Available through the VIMS display, the operator can quickly view each tire’s pressure and take action when needed to reduce wear and increase service life.
