3. Concept of 3D Excavator Systems  GPS senors in combination with angle sensors locate precisely the position of the tip of bucket in real time  position is displayed to the operator on the a onboard computer  bucket tip position is shown relative to design  enables the operator to dig to precise limits without any stakes

4. Accuracy  GPS itself can determine the antenna position within +/-20mm.  most manufacturer state an accuracy of the tip of the bucket within +/-50 to 70mm.  Remember: –a big number of buckets in use take several m³ in one go, they often do not look that much for mm –the size of an excavator is significantly important for the accuracy needs of the customer –the kind and size of the material influences the highest possible and reachable accuracy

5. Benefits of 3D Excavator Systems  Never undercut or overfill –even if the material might not be that expensive - to dig it out, to bring it away and to dump it off is often very expensive. Just think on the costs and time of the other machines and people involved  Increased productivity –the operator has all information all the time available in the cabine. No downtimes in the production because of missing stakes or information. No grade checking anymore  Improved recovery and repeatability –day to day follow up is very easy and out of the DTM anything can be controlled at any time from anybody

6. Benefits of 3D Excavator Systems  Lower operation and maintenance costs –most efficient usage of the excavator and trucks end up in short time cost savings (fuel and time) and in long terms in service in life-periodical costs  Tremendous time savings over the length of the project –operator does not have to wait for new stakes or information and is not jumping out of the cabine for accuracy checks and on top grade checking is done during the production  Eliminate staking and continue where stakes are impractical –just think on the cost of the stakes and to bring them out again and again

7.  Real-time "as-built" survey –finished and precisely done in the first go –same precision over the whole project  Safer then putting a surveyor "on the ground" next to heavy machinery, under high walls, or in trenches –extreme reduction of risks in some areas and applications  Indicates danger zones –avoided zones can be indicated which again reduces the risks for the staff and the machines Benefits of 3D Excavator Systems

8.  Glonass satellite availability in combination with GPS can give better satellite coverage for deep-pit applications  Some payback periods as low as 3 days, most are under 6 months  Easy to learn –operators catch the functionality in less than half a day. They love the system after the first day. Benefits of 3D Excavator Systems

9.  Excavate to Design –earth and rock excavation can be completed in the first go to the design without any survey stakes –Nearly no chance of errors and over-excavation –surveyors work on further designs, or rework actual design, instead of continually replacing stakes –guess work is completely taken out, by a 100% coverage over the whole design file Benefits of 3D Excavator Systems

10.  Excavate to Design –even if the operation is in deep wholes or under water, where the operator can not see the position of the bucket tip and how fare he is away from finished design, he can do his job…  better  faster and  more accurate than anyone else Benefits of 3D Excavator Systems
