Dana Incorporated recently debuted its selection of drive and motion technologies that support electrification. The company demonstrated its two construction machines at Bauma, a construction and mining exhibition.
A mid-sized aerial work platform (AWP) with an 18-meter (60-foot) platform height and a 1.5 ton (3,300-lb.) mini excavator illustrate how Dana offers to enhance the productivity, mobility, and efficiency of electric-powered vehicles.
Dana’s High-Efficiency Electrified Aerial Work Platform
Featuring more than 30 of Dana’s drive and motion products, this AWP demonstrator has a non-traditional four-wheel-drive design to demonstrate the range and effectiveness of Dana’s e-Mobility capabilities.
A Spicer® Electrified™ e-Axle powered by an integrated SME® motor and inverter supports the steering function at the front of the AWP, while the rear is equipped with two Spicer Electrified e-Hub drives.
The Spicer Electrified e-Axle configures Spicer axle components and drive and motion intelligence, SME motor and control technologies, and advanced gearing in a modular package that can be fine-tuned for vehicle size and performance. The optimized combination of electrified drive components reduces power losses by up to 20 percent when compared with traditional diesel-powered drivetrains.
The AWP demonstrator uses advanced mechatronics technologies to govern traction, stability, and safety in work environments. It has an electronic differential and torque vectoring control that manage power distribution to the wheel ends to provide necessary tractive force in a regulated, safe manner. The AWP also employs a stability control system that monitors the distribution of weight across the machine and automatically takes action to prevent tip-over incidents.
The AWP also features advanced Spicer control software for vehicle management as well as numerous Brevini® motion products in the work circuits, including customized hydraulic blocks, hydraulic valves, gear pumps, electronic controller units, and operator-information displays.
Compact, Quiet Technologies for Electric-Drive Mini Excavator
Dana’s electric-driven mini excavator uses SME electric motors and inverters to power drive and motion functions across the machine, including four Spicer Electrified e-Hub drives that provide a top travel speed of 4 kph (2.5 mph).
Meanwhile, a new Brevini hydraulic smart block manages the vehicle’s work functions more efficiently and precisely than a comparable diesel-driven machine. The mini excavator is also equipped with a Brevini slew drive, human-machine interfaces, electronic controller units, and operator-information displays.
