US EPA Tier 2/elsewhere: US EPA Tier 1

The all-rounder for mining soft and hard rock

  • The powerful surface miner is used for the selective mining of raw materials with unconfined compressive strengths of up to 80 MPa and for routing work.
  • The 8 ft. 2 in. (2.50 m) cutting drum unit – tailored to the job – with a cutting depth of 2.6 in. (650 mm) guarantees high production rates with minimum tool wear.
  • Trucks with a load capacity of between 40 and 120 tons can be loaded using the powerful liftable and slewable rear-loading conveyor.
  • Individually height-adjustable and steerable crawler units enable optimum manoeuvrability.
  • The fully glazed operator's cabin is heatable, air-conditioned, soundproof and vibration-proof, providing a less tiring and productive machine operation.

Surface Mining

As the surface miner moves forward, a special cutting drum rotates against the direction of travel, cutting layers of material from the rock formations and crushing it in the process. The primary conveyor picks up the material in the drum housing and transports it towards the rear of the machine, where it is then accepted by the slewable and height-adjustable discharge conveyor. The discharge conveyor loads the material into trucks or dumpers or discharges it to the side of the miner. The discharge height can be adjusted to the height of the transport vehicles. The surface miner is driven via four steerable and height-adjustable track units. An automatic leveling system ensures precise adherence to the cutting depth, thus enabling even thin seams or layers to be mined selectively and with maximum accuracy.

WIRTGEN cutting technology

High quality results are the goal of every construction project. This applies to road rehabilitation using cold milling machines and cold recyclers as well as to soil stabilization and the extraction of minerals with surface miners. In order to remove pavement with precision and efficiency, it is essential that the drum, pick holder, and pick work together perfectly.

WIRTGEN is the market leader in cutting technology and offers customers high-performance cutting systems whose components are designed to be fully compatible. In addition, WIRTGEN continuously makes advancements to these cutting technology components, incorporating its practical experience and feedback from customers into the process.

WIRTGEN leveling technology

WIRTGEN’s leveling technology adjusts height, depth, and pitch for extremely accurate results. In the process, the system permanently compares the actual values to predefined target values and adjusts the deviations proportionally. This state-of-the-art machine technology consistently guarantees outstanding leveling results and significantly reduces the machine operator’s workload.

WIRTGEN offers customers reliable hardware and software developed in-house. In this context, a variety of systems are used depending on the construction project and local conditions at the job site.
