Mine operators are embracing technologies that enable them to become future-proof
THE MINE OF THE FUTURE Ralf Matke discusses the considerations required for moving the big things
n a world of deeper mines with more complex ore bodies, rising energy costs, infrastructure shortages and resource nationalism, mining companies remain under exceptional pressure to control costs, heighten effi ciency and improve safety performance. Although there are no easy solutions, it becomes increasingly apparent that technology will play a growing role in the mine of the future. Mining applications, from large
I
crushers, roller mills and apron feeders to massive crawler excavators must withstand heavy-duty operating conditions and at the same time be compact, precise, effi cient and guarantee safety. T e industrial gearbox product line of ZF answers these requirements. New developments such as a modular gearbox design guarantee fl exibility and lower costs. “We support our customers with the right product and application knowhow, quality and reliability. We use the latest technology developments in the fi elds of gearboxes, electrifi cation and digitalisation,” says Christoph Kainzbauer, head of industrial gearboxes at ZF. “Facing the current global challenges, the required reduction of resources and energy consumption as well as sustainability, we developed

and launched the next generation of planetary drives. With the Redulus4F
series our customers are prepared for the future.”
FUTURE-PROOF POWER PACKS ZF’s newest Redulus4F
gearbox design is
designed to be integrated in multiple large applications for the mining industry, such as conveyor systems, apron feeders, grinding or large crushing machines and more. Various market requirements
were considered during the product development. A construction kit off ers a solution for multiple customers and applications in diff erent industries. As an example, the gearbox is not only installed in mining equipment, but also in high- pressure grinding roller mills and other large industrial applications. T e fl exible and compact design off ers over 2,000 customised possibilities, all guaranteeing maximal output. T e new construction
kit includes 20 sizes, which supports an optimised selection of torque and size. It delivers up to 40% more torque compared with the previous generation and covers a broad torque range from 100,000Nm up to 6,000,000Nm. In the end, the higher torque capacity enables the fi rm’s engineers to fi netune the gearbox selection with either a smaller gearbox with less weight or with a higher safety margin with increased lifetime. T e total cost of ownership (TCO) is reduced signifi cantly.
GEARBOXES FOR MOBILE APPLICATIONS It’s not only stationary mining challenges that drive technology; there is also a need for heavy-duty mobile equipment in open pit mines. Cubic metres of material
