25 % more cutting performance 15 % less fuel consumption CONTINUOUS PROCESS OF IMPROVEMENT POSITIVE EFFECTS EXEMPLIFIED IN COAL MINING A continuous process of improvement for our customers’ benefit is one of the fundamental company philosophies cultivated by WIRTGEN – the market leader in surface mining. A series of improvements implemented in the WIRTGEN 2200 SM 3.8 surface miner for use in, for example, Indian coal mines resulted in a significant increase in productivity in comparison with the standard model. Increasing both the cutting performance and effective uptime is one of our main priorities...

The new 2200 SM 3.8 impresses with an increase in cutting performance by 25% and a reduction in fuel consumption by 15%.

The improved miner cuts soft rock selectively at maximum production rates and economic efficiency. Economical mining of soft rock HIGH PRODUCTION RATES USING THE WINDROWING PROCESS Mining soft rock at maximum production rates and economic efficiency – the 2200 SM 3.8 surface miner has been developed to meet exactly these criteria for success. The centrepiece of the compact, yet powerful machine is the 3.8 m wide cutting drum which offers numerous innovative features. It cuts soft rock with unconfined compressive strengths of up to 35 MPa, such as coal or salt, in a highly productive process,...

CUTTING PERFORMANCE, LAMINAR OR BRITTLE SOFT ROCK (SUCH AS COAL) 2,000 Unconfined compressive strength (MPa) optimized for soft rock standard A single operation instead of four – with the 2200 SM 3.8 surface miner from WIRTGEN.

THE TREMENDOUS CUTTING POWER OF WIRTGEN CUTTING DRUMS CANNOT ONLY BE SEEN. IT CAN LITERALLY BE FELT. BECAUSE OF THE HEAVY-DUTY CUTTING DRUM DESIGN TAILORED TO PERFORMANCE REQUIREMENTS. MANUFACTURED FROM EXTREMELY WEAR-RESISTANT MATERIALS. BASED ON SPECIFIC EXPERTISE GAINED IN SEVERAL DECADES OF EXPERIENCE IN CUTTING TECHNOLOGY. COST-OPTIMIZED. SO THAT WE CANNOT ONLY MEET BUT EXCEED YOUR REQUIREMENTS IN EFFICIENCY AND PRODUCTIVITY.

Cutting drum unit precisely tailored to the mining of soft rock 12 13 3.8-M WIDE CUTTING DRUM UNIT OPTIMIZED FOR SOFT ROCK 1 | Cutting circle diameter increased from 1,115 mm to 1,300 mm for high working depth and high mining volumes 5 | Increased, heavy-duty cutting drum housing fully welded at the front for low wear and tear in tough operating conditions 2 | Special cutting drum developed for the windrowing process with high, slender holder bases but without conveying helices for minimum energy requirements 6 | Larger openings in the scraper blade and additional baffle plates to optimize the...

DESIGNED FOR TOP PERFORMANCE The robust, 3.8-m wide cutting drum assembly is based not only on field-proven components but also on concepts developed specifically for the highly productive mining of soft rock. The cutting drum housing consists entirely of highly wear-resistant material. Effective closure of the drum assembly on the left and right is ensured by two hydraulically lifting side plates. The integrated water spray system reduces dust development when cutting dry useful minerals. Three large material dis- charge openings in the scraper blade allow large amounts of material to be deposited...

BE RELAXED AND COMFORTABLE DURING WORK WHILE KEEPING EVERYTHING IN FULL VIEW – A GIVEN WITH THE 2200 SM 3.8. CLEARLY STRUCTURED CONTROLS ARRANGED IN LINE WITH ERGONOMIC PRINCIPLES. PROVIDING THE OPERATOR WITH ALL RELEVANT PARAMETERS AT A SINGLE GLANCE. THE INTELLIGENT VISIBILITY CONCEPT COMES AS STANDARD. WITH THE 2200 SM 3.8, YOU ARE IN FULL CONTROL. EASE OF HANDLING AND HIGH PRODUCTIVITY BECOME ONE.

Ample space, ergonomic design, comfort features and good visibility to both sides thanks to large glass windows ensure high operator comfort. Work at ease and in a protected environment RELAXED WORKING BOOSTS PRODUCTIVITY Inside the cabin, the operator is protected from outside influences such as extremely high or low temperatures, wind, rain, dust, vibrations or high noise levels.
