A BIG IDEA. MINING VALUABLE RAW MATERIALS SELECTIVELY NOT IN FOUR WORK STEPS BUT IN A SINGLE OPERATION. WITH THE WIRTGEN 4200 SM. A HIGH-PERFORMANCE SURFACE MINER IN HEAVY-DUTY DESIGN FOR RELIABLE, CONTINUOUS OPERATION AROUND THE CLOCK. EQUIPPED WITH OUR EXPERTISE IN STATE-OF-THE-ART CUTTING TECHNOLOGY. WITHOUT DRILLING AND BLASTING BUT IN A HIGHLY ENVIRONMENTALLY GENTLE PROCESS YIELDING MATERIAL OF THE PUREST QUALITY. WIRTGEN SURFACE MINING – EXPLOITING MINERAL DEPOSITS THE INTELLIGENT WAY.

High cutting performance and economic efficiency are hallmarks of the 4200 SM. Reaching new performance levels with the 4200 SM ANNUAL MINING CAPACITY OF UP TO 12 MILLION TONNES The 4200 SM is the ideal candidate for the mining of hard rock or soft rock on a truly grand scale. Tremendous mining capacity, unmatched economic efficiency and flexible adaptability to most diverse operating conditions and mining regulations count among its outstanding hallmarks. Instead of requiring four operating steps, which is normal for conventional mining methods, up to 3,000 tonnes per hour of material can be...

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.

The cutting drum is tailored to application requirements to enable maximum cutting performance. Cutting drum tailored to performance requirements APPLICATION-SPECIFIC DRUM DESIGN Cutting drums for the WIRTGEN 4200 SM are made-to-measure products: they are tailored to the hardness of the material to be mined and to customer-specific requirements. The process of customizing the cutting drum design to application requirements - including the use of most diverse hard-wearing mining tools and toolholder systems – is based on the unmatched expertise gained in several decades of experience in cutting...

1 | HT15 reduces the time required to replace a single toolholder from 90 minutes to only 15 minutes compared to conventional, welded toolholder systems. 2 | Each cutting drum is designed in line with the specific operating conditions it is intended for. HT15 QUICK-CHANGE TOOLHOLDER SYSTEM The innovative HT15 quick-change toolholder system ensures maximum tool utilization while minimizing breaks in operation. 1 | Specially heat-treated holder shank for increased strength 2 | Heavy-duty shank mounting for the use of WIRTGEN point-attack cutting tools 3 | Precise contact surfaces between upper...

Technically mature loading. WIRTGEN SURFACE MINERS ARE EXPECTED TO DELIVER TOP PERFORMANCE CONTINUOUSLY AND IN EVERY REGARD. MATERIAL LOADING INCLUDED. THE LOADING CONVEYOR OF THE 4200 SM IS READY TO TAKE ON EVERY CHALLENGE. TO UP TO 2,400 SOLID CUBIC METRES PER HOUR. WITH APPLICATION-SPECIFIC FLEXIBILITY COMING AS A STANDARD FEATURE. THANKS TO TREMENDOUS SLEWING ANGLES, HEIGHT-ADJUSTABLE LOADING CONVEYOR AND VARIABLE CONVEYING SPEED. COMBINING PIONEERING POWER AND TECHNOLOGY – MADE BY WIRTGEN.

The high-performance discharge conveyor allows direct loading into trucks or dumpers. Filling huge dump trucks in record time FLEXIBILITY COMES AS A STANDARD FEATURE Optimized loading is of vital importance to ensure the economical mining of large mineral deposits. Not only the generous conveying capacity of the 4200 SM’s loading conveyor leads by example in this regard, however, but also its outstanding flexibility: a tremendous slewing angle of 180°, height adjustment and continuously adjustable belt speed ensure the smooth loading of large transport trucks even in restricted space conditions....

1 | Slewing angles of up to 90° to either side allow perfect adjustment to conditions in the mine. 3 | The movable counterweight provides stability and is easily retracted when working along steep high slopes.

BE RELAXED AND COMFORTABLE DURING WORK WHILE KEEPING EVERYTHING IN FULL VIEW – A GIVEN WITH THE 4200 SM. 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 4200 SM, YOU ARE IN FULL CONTROL. EASE OF HANDLING AND HIGH PRODUCTIVITY BECOME ONE.

No cutback on operator comfort ERGONOMIC DESIGN SUPPORTS THE OPERATOR Keeping production rates of the 4200 SM at consistently high levels requires an operator who is able to fully focus on his work during the entire work shift. We have therefore made sure that he feels safe and comfortable. The cabin is equipped with air-conditioning and heating systems. It is located above the front left track unit, on the side opposite the slope and away from the cutting drum and engine. It offers full soundproofing and is isolated against vibration. Four cameras plus screen provide the operator with a full...
