switches to more efficient diesel- electric operation for less-demanding applications. The OEM’s hybrid energy solutions provide renewable electric power to stationary locations in remote areas via a combination of generator sets, solar and energy storage building blocks. Cat electrified products at bauma 2019 As they look for more reductions in CO 2 emissions, many of Caterpillar’s customers, especially in Europe, are already seeking out electrification solutions. That’s why the company made it a priority to showcase a number of its newest electrified products at bauma 2019. Visitors to the show got an up-close look at the D6 XE dozer – said to be the world’s first with high-drive electric drive, which improves fuel efficiency up to 35%; the 988K XE wheel loader, which features a high-efficiency electric drive system with switched reluctance technology; the 300.9D VPS mini-excavator, which produces zero emissions when connected to a remote power unit; and the 906 compact wheel loader, a concept vehicle with a fully electric drivetrain powered by a lithium- ion battery. Collaboration drives innovation Developing the right electrified products for its customers’ diverse needs isn’t something Caterpillar is doing alone. Its dealers around the world are on the front lines of the electrification movement –

“Though every industry we serve is unique, our customers share many goals – among them working more productively, efficiently and cost- effectively. To help them adapt to electrification more quickly, at a lower cost and with less risk, we will be applying tried-and-true concepts across industries, applications and products large and small.”

needs – and why we are pursuing not a single solution, but a versatile approach that lets us match the right product to the application,” says Umpleby. Caterpillar’s electrified product range includes fully electric products. Featuring single or multiple non-engine electric power sources, the products are best suited for environments where eliminating emissions is key — underground, indoors, urban areas and some agricultural segments. Many of Caterpillar’s electric rope shovels, draglines and oil and gas compression products have long been fully electric. In 2017, the OEM created a proof-of-concept R1300 underground loader with a battery-electric powertrain, which is now driving the development of its next generation battery-powered R1700 mining loader. Another area is diesel-electric products. Connecting an engine to an electric

generator, AC drive motor or other source of electric power, these products are ideal for operations where using less fuel is a priority. Caterpillar’s D7E dozer, which first went to work in 2009, features a diesel-electric powertrain that delivers up to 30% better fuel efficiency – saving customers millions of litres of fuel over the last decade. Other examples of diesel-electric products in our portfolio include the 794 AC and 795F AC electric drive trucks and Electro- Motive locomotives. sources – batteries, tethered or cable- powered electric systems, hydraulic accumulators, high-speed flywheels – can reduce emissions and improve efficiency. Caterpillar’s marine hybrid propulsion system delivers full diesel- mechanical power in work mode, then The third product area is hybrid machines. Working alongside an engine, numerous other power
