Tests of the new MoAZ-4057 underground loader on lithium-ion batteries have begun at the Mogilev branch of the testing center – BELAZ presented the first 10-ton electric-powered mining loading and hauling machine of this class as part of a joint project with Nornickel.
The machine is designed for operation in deep mines and aims to reduce dependence on diesel equipment underground. The power unit is based on a traction lithium-ion battery pack, which powers asynchronous electric motors with a total power of 145 kW. A 4.1 m³ bucket allows it to operate in the heavy underground loader class, maintaining high productivity with compact dimensions.
Special emphasis is placed on continuous operation: a scheme with interchangeable battery modules is used, where one block provides machine movement, and the second is charged at a stationary station. Full charging takes about two hours, which minimizes technological downtime.
The developers note that the transition to electric traction in mining equipment significantly reduces noise levels and completely eliminates emissions, which directly affects the safety and economics of underground operations. In the future, this reduces the load on ventilation systems and cuts operating costs in large mines.
After the completion of acceptance tests, the prototype is planned to be sent to one of the deepest mines in the Norilsk industrial region in Krasnoyarsk Krai, where the equipment will be tested under the most stringent operating conditions.
