Aramac L140B Loader automates underground mining at Cemex Germany

The future of European resource extraction has taken a significant leap forward.

Aramine and sensmore have announced a partnership to introduce an automated, battery-powered Aramac L140B loader into the underground production environment at Cemex in Germany. This collaboration transforms a proven underground machine into a fully autonomous production system designed for real operating conditions.

As Europe actively seeks secure access to critical raw materials, underground extraction must become safer, more efficient, and less dependent on scarce skilled labour. Autonomous machines represent a practical path to achieving these vital goals by greatly reducing operator exposure to demanding underground environments.

Marc Melkonian, co-president at Aramine in charge of the equipment division, highlighted the strategic importance of this development. "The next step is to take raw materials under our feet, under our ground, in Europe, and not on the other side of the world. For that, we are not going to send people underground, but we are going to send machines that are capable to do it by themselves," said Melkonian.

The hardware driving this initiative is the Aramac L140B loader, provided by Aramine. Launched in 2016 to introduce new technology into underground mining, this battery-powered machine was explicitly designed with the openness required for autonomous control. Featuring a 1.3-tonne payload, it is engineered specifically for the distinct challenges of narrow-vein mining. The L140B successfully combines productivity, manoeuvrability, and operational flexibility in confined underground spaces. Operating with zero local CO2 emissions, the loader supports safer mining environments whilst enabling the transition toward fully autonomous production.

While Aramine provides the physical platform, sensmore acts as the automation system provider. The software company turns the L140B into an intelligent, autonomous production machine. The integration encompasses the entire automation stack, safety architecture, machine control, and operational interfaces required for active production use. At Cemex in Rüdersdorf, sensmore connected the automated L140B to the entire production process, including the conveyor belt, functional safety networks, and site infrastructure. Consequently, the machine operates not as an isolated robot, but as an integral part of the continuous underground workflow.

"Autonomy in heavy industry only creates real value when it is vertically integrated into the production environment," said Maximilian Rolf, CEO and Co-founder of sensmore. "At Cemex, we are integrating the Aramine L140B into the entire underground process. That is how autonomous machines become part of industrial reality today".

The operational impact of this deployment is already highly visible. Christian Zinnecker, coordinator underground operations, extraction & blasting at Cemex, noted the project's significance. "Implementing this system is a major milestone for us. It helps improve productivity, reduces operator exposure to underground risks, and supports our journey toward safer and lower-emission mining operations" said Zinnecker.

The automated Aramac L140B boasts remarkable endurance, operating autonomously for up to eight hours, compared with around five hours in manual, manned mode. This substantial increase translates into greater machine availability, a reduction in repetitive tasks, and a significantly safer working environment underground.

Together, Aramine, sensmore, and Cemex are demonstrating that autonomous underground extraction is no longer a future concept. It is becoming an industrial reality: safer for people, easier to operate, and fully ready to support the next generation of underground resource production.
