260 SXi Surface Miner

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 levelling system ensures precise adherence to the cutting depth, thus enabling even thin seams or layers to be mined selectively and with maximum accuracy.

Results of high quality are the main 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 useful minerals using surface miners. Optimum interaction between the milling drum, toolholder and pick is essential for precise, efficient paving removal.

WIRTGEN is a market leader in cutting technology and offers customers perfectly matched, high-performance cutting systems. WIRTGEN is also constantly developing its cutting technology components further. Such further developments are largely based on practical experience and feedback from our customers.

WIRTGEN levelling technology controls height, depth and slope to achieve results of maximum precision. In the process, the system continuously reconciles the actual values with a preselected target value, correcting any deviations by means of proportional control. State-of-the-art machine engineering ensures levelling results of consistently high quality while at the same time relieving the machine operator of a significant part of his workload.

WIRTGEN offers customers reliable hardware and software developed in-house. Different systems are used depending on the construction project to be completed and local conditions on site.
