What you can be sure is coming within the next 5 years is more machine automation. Autonomy Is the FutureĪlthough some grade control systems allow an extra benefit that controls the work, it is still routinely left up to the operator to properly follow the programmed coordinates. Some grade control system manufacturers provide their customers with website access, making this information available to remote fleet managers or owners who are not at the jobsite. If you aren’t routinely on your jobsites, you can still monitor your excavator operator and the machine’s grade control system. The system gives an indication of how far above or below grade you’re working, based on the tip of the bucket. Using the second monitor installed in the cab, your operator can see the location of the bucket and the programmed dig depth requirements. Your operators are still in control of the excavator. The system provides real-time information to your operators to ensure the project is being done correctly. Once the system is installed on your excavator, your operators have a wealth of information available to increase their proficiency. ![]() These information sources help your operator accurately position the excavator bucket in real time as the bucket, boom and arm move. Grade control systems use information gathered from global navigation satellite systems, GPS, laser, sonic or total station technology. In addition, a monitor is installed in the excavator cab that provides vital information to the operator. Once installed, these components are likely to stay on that machine for the its useful life. Two receivers (masts) situated on the back of the excavator above the counterweight.Components of grade control systems include: ![]() They can help you properly install the components on your excavator, provide training and ensure it’s working correctly before you transport your machine to the jobsite. Once you decide to add a grade control system to your excavator, you will need to work with your local dealer and a technology expert from the company that developed the system. Its GC900 Grade Control System is available for excavators and can be particularly useful in the 25- to 35-metric-ton excavator size class, based on the type of work these machines perform on a regular basis. You can choose from several tech companies that have developed the technology for grade control. The 3D guidance system is especially beneficial for operators working on complex designs, like larger-scale drainage projects. The excavator can be moved on your jobsite and still dig on grade. Three-dimensional grade control systems allow you or your excavator operator to add variable distances, such as a curved line or a curved trench. You can expect a consistent grade on a vertical plane. Your operator knows the grade is correct from point A to point B to dig a straight-line trench. Two-dimensional grade control systems allow your excavator operator to work off a single plane-whether it be flat, single or dual slope. You can choose between two grade control systems-2D or 3D-depending on the type of work that you’re doing. And that means adding more Class 5 base material before the footing can be done. When this happens, you are required to add material back in your trench. Another system benefit is avoiding overdigging. ![]() And it can be safer to have fewer employees working outside of equipment on a construction jobsite. With a grade control system, you can also eliminate the need for an employee to check the grade, freeing them to do other work at your jobsite while your excavator operator maintains an accurate grade.
