Caterpillar’s new Cat 988K XE, the first wheeled loader offered by the company with a high-efficiency electric drive system, will makes its introduction at steinexpo 2017 in Germany (30 August-2 September).

The loader joins the 988K and the recently-launched 986K wheeled loaders to provide customers with a 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.

Caterpillar says 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.

Offering increased truck loading and load-and-carry efficiency, 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. At the same time, Caterpillar production studies report the new loader delivers up to 10% higher productivity in load-and-carry applications,” says Caterpillar.

The new Cat 988K XE loader offers a range of bucket capacities from 4.7-13m3, and 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.

Caterpillar says the standard 988K XE wheel loader is performance matched to offer efficient three-pass loading of the 38.6tonne Cat 770G and four-pass loading of the 46.3tonne Cat 772. Its high-lift configuration delivers five-pass loading of the 55.3tonne Cat 773G and six-pass loading of the 64tonne Cat 775G.

Cat electric drive technology found in the new 988K XE lowers overall maintenance costs, while increasing engine life expectancy, says Caterpillar. Offering extended oil change intervals of 2,000 hours, the electric drive wheeled 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,” says Caterpillar.

“To assist with electric drive rebuilds, Caterpillar offers customers world-class service training material, backed by 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 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 new Cat 988K XE loader is equipped with a host of technology solutions to increase operating efficiency and machine uptime,” says Caterpillar.

“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.”

Optional Tyre Pressure Monitoring System (TPMS) is a fully integrated Cat feature, which enables operators to monitor tyre inflation.
