GPS or Global Positioning System has now been included in the earthmoving industries. Heavy equipment manufacturers are now applying this technology in their procedures. These are for land grading, roads, causeways, railway beds, levees, dams, berms, and canals.
A lot of modification and advances in technology, as well as innovation and efficiency with the lesser profit involved, pushed certain kinds of developments. One of these developments is the use of GPS machine control files that are being adapted into earthwork. It can reduce the cost for contractors and would make work faster with the use of these technologies.
Late 1990s was the beginning of heavy equipment corporations to innovate this technology while dominating the market sector for this type of procedure as well as advancing the process even further. This simply works by comparing the positions of the blade with the current location of the graders. It gives the difference while making it able to automatically adjust itself. Making these place holders for location is the use of the GPS.
Various 2D and 3D software are being developed for this procedure. The model for this will then be visualized into either 2D or 3D to allow the operator to study the area further. A lot of companies have been developing their own software and upgrading them for further development and added accuracy.
There are two types of systems that are being used in earthmoving for the heavy equipment industry. They are simply categorized as Indicate Only and Fully Automatic. These two systems can use one or also two of the receivers. Having only one would limit the guidance system in the orientation of the position of the machine. Having two would allow two points of the position which gives also the angle of the machine in relation to the site plan.
In order for accuracy with this use, there should be an accurate site design as well. The design file that came from an engineering firm can be imported into the GPS display. Some guidance systems will also allow the user to define the grade elevation and angle without the specifics of the original design.
Examples of heavy equipment that can be installed with a guidance system are Motor Graders, Hydraulic Excavators, Scrapers, and Compactors. It would help greatly for these machines in accuracy, efficiency, time, and cost effectivity. It also provides less on site manual management by field workers.
For one machine it has a cost of about one hundred million dollars. If used efficiently, it can be thirty percent more productive than the traditional methods. Due to the high accuracy, there is less materials that are needed and cost. That is why most construction projects have GPS as a requirement in order to lessen the cost.
There are a few limitations but these are not as bad as they are but should still be considered. Since the system uses satellite signals, obstructions in the environment of the project site may cause it to not function properly. Dead zones may be created due to the roofs of buildings and other establishments nearby. But even if this is true, the use of Global Positioning System is still a standard for advanced Earthmoving.
