Normet launches ElectroDynamic architecture, XL ED platform

In a move it says will define the future of underground transportation, Normet is introducing its Normet ElectroDynamic (ED) powertrain architecture and the XL ED platform.

By combining the best features of its battery-electric Normet SmartDrive platform and state-of-the-art low-emission engine technology, the company said the Normet ElectroDynamic architecture allows for increased payload capacity with astonishingly compact outer dimensions while also ensuring superior driving dynamics, high performance, superb fuel efficiency and less need for maintenance.

A key element of the ElectroDynamic technology is that the need for drive shaft and gearbox is eliminated through driving the externally cooled mining axles with permanent magnet motors in a highly efficient direct-drive configuration. This not only renders a low and compact load end design, instant torque and economical electric retardation possible, but also significantly increases component lifetime.

“As we were developing our battery-electric SmartDrive equipment, we quickly realized that we can actually remove the drive shaft and gearbox from engine powered equipment as well,” said technology director Samu Kukkonen.

“This is monumental, because now we can utilize the space where the drive shaft used to be for increased payload capacity. This was achieved by utilizing electric motors at the axles powered by a low emission engine-generator set. What is more, we have years of experience with all the components used in the architecture not only from our SmartDrive equipment, but also from our engine powered equipment.”

Normet ElectroDynamic architecture also enables one-pedal driving, where the vehicle automatically controls both acceleration and deceleration with the operator’s accelerator pedal input. Additionally, its advanced front axle suspension system and the new Normet 180° cabin with improved ergonomics and visibility set new industry standards for operator safety and comfort.

Introducing the Utimec XL ED
The completely new Utimec XL ED carrier is designed for heavy-duty underground transportation applications with its remarkable payload capacity of 24 tonnes. All models in the XL ED offering are built on the new Normet ElectroDynamic technology.

Built with some of the highest-quality powertrain components and robust frame structures, all XL ED units are powered with direct-drive electric motors, Volvo Penta engines with Stage V emission rating, enabling clean and efficient operation.

Utimec XL 1100 Agitator ED with a practical concrete transportation capacity of 10.5 m³ is designed for concrete transportation in underground mines and tunnels with a minimum tramming height of 3.3 meters.

Tailor-made for harsh underground conditions, the vehicle is equipped with a voluminous, wear-resistant and remote-controllable concrete drum and a hydraulically operated discharging chute, allowing for more versatile vehicle positioning. Both mixing and unloading are controlled electrically and can be operated with zero local emissions by plugging the machine into the mine’s power grid. This increases operator comfort by significantly reducing heat output and noise and by eliminating underground emissions.

Moreover, the XL 1100 Agitator ED comes with a spectrum of useful features such as both front and rear support legs to ensure maximum operating stability, a form oil system to effectively prevent concrete from adhering to the vehicle’s surfaces and a high-pressure washer with a 500-litre on-board water tank.

“We are immensely proud of the new Normet ElectroDynamic technology and the XL offering, both reflecting our passion for continuously developing innovative solutions and technologies to meet and exceed customer and industry expectations for safety, productivity, and sustainability,” Normet said.
