Description
The W22 Mining motors can operate with high efficiency in the severest applications. They have special mechanical characteristics that ensure durability, mechanical strength, and robustness in every step of the mining process – from extraction and transportation to the ore processing. Furthermore, they require low maintenance, significantly reducing undesirable downtime, and providing greater plant availability.
