South Korea-based manufacturer Hyundai is to attend this year鈥檚 Bauma exhibition, where it will reveal a concept hydrogen-fuel-cell-powered wheeled excavator.

The new 14 tonne excavator, the HW155H, promises eight hours of operation, with a 20-minute refuelling time 鈥� and the only emission is water.

The manufacturer will also showcase its range of excavators, wheeled loaders and articulated dump trucks (ADTs).

Working under the theme of Think Further, Think Future, the company will also unveil two new ADTs, the HA30A and HA45A, with payloads of 28 and 41 tonnes respectively.

The ADTs have been designed with sloping rear chassis frames, enhancing stability by distributing more of the load on the centre of the machine.

According to Hyundai, the ADTs are also built to hug the ground, with tandem rear bogie axles offering a high level of ground contact and 鈥渂est in class traction.鈥� On both machines, an articulation joint turning ring is mounted close to the front axle, promoting equal load distribution.

This equal weight distribution allows the operator to use the limited slip differentials with just a 45掳 locking value, maintaining drive to both front wheels even when steering.

The Hyundai stand will incorporate a range of technologies, but it will also have a separate technology zone in the ICT hall, where it will demonstrate both existing innovations and the company鈥檚 vision for the future.

Highlights will include sustainable solutions for energy, including electric and hydrogen fuel-cell technology for construction machinery.
