GPS levellers for roads

Mara Laser is a business activity that for 30 years and more has been analyzing, producing and trading laser and GPS controlled laser levellers, calling on clients in about 30 nations all over the world.
Thanks to GPS and laser control technologies, we can reach important results in many areas of use: from agricultural soil to sport facilities, from building constructions to road excavations, from landscaping to soil scraping.
Mara’s levellers ensure a series of advantages and high productivity in more than one situations: from the machine running speed regime, to a total trustworthiness and assurance of the result.

Mara’s technology

The technology used by Mara is what makes it unbeatable, and the results obtained all over the world are proof of this. Laser and GPS receiver technologies provide an unique performance, in particular when they are combined.

Laser technology

Laser technology is applied to the levellers in a way that continually synchronize the height of the blade.
The laser leveller, the laser beam transmitter and the laser beam receiver are the elements of the laser control system for levelling.
The transmitter is placed on a tripod that examines the natural gradient of the land and communicates the signal to the receiver, which is instead put on the machine itself.
The laser beam, as it is one of its internal characteristics, permits very high accuracy even over long land portions. After getting the signal, a technologically perfectioned rotating pentaprism, put on these machines, gives back an ideal planning for the leveller to follow while running.
The receiver also has an important role, because it correctly reads the laser light received from the transmitter, through special photodiodes. The receivers, made by Mara Laser, guarantee the levellers will be able to move on any kind of soil and receive the 360° signal, though it could be low or it is subjected to interference.
On the laser leveller, besides, there is a control system to remove external interference. It decreases wind rumble, automatically reaches the signal and sets the power of the tractor.

GPS receiver technology

GPS technology, after all, is used to regulate the position of the laser leveller and the height of the blade.
The levellers, that implement this technology, perceive the laser signal from the satellites: even in this situation the planning is represented by the signal and reproduced on the land.
Lately, thanks to technological advancement and the use of dedicated software, an accuracy of ± 10 mm has been reached up, even though this technology offers less accuracy than laser technology: GPS systems are subject to fluctuations as it is one of the periodic change of constellation of the satellites.
In any case, the less accuracy is compensated by the wide elasticity of use, in particular when this technology is used to work on large land portions with more than one inclinations, such as agricultural soil and building constructions.

Integrated laser + GPS system

Mara Laser has produced and made an integrated system that connects the precision of laser technology with the potential of GPS, the right one for harsh land.
The higher accuracy of the laser signal represents the plan within a radius of 1300 meters, while the GPS system communicates the precise spot of the leveller. Therefor, the Mara system can regulate the height of the tractor leveller and the precise spot of the blade itself.
The creation of the 3D map of the land permits to highlight the land portions that has to be scraped, the loading areas, the starting point, and the best route that enables to make the best work possible, with both the tractor and the leveller in the right position.
Therefor, the operator will have instant instructions through the constant updating of the data by the system.

Fields of application

The important accuracy and elasticity of the levellers made by Mara Laser assure their use in more than one fields:

  • Laser levelling machines for agriculture:
    Mara’s laser levellers, among the many plus assure a key increase of the arable land portions. They permits a reduction in the amount of water used, an increased production, a considerable reduction of chemicals used, as well as seeds. The lowering in work hours, furthermore, makes the use of these machines a sure investment.
  • Laser levelling machines for construction:
    Mara Laser gives an absolute perfect precision to obtain ground floors with very contained deflections (max 4 mm) and to remove cavities and gaps that would, afterwords, be filled with concrete. The lowering of work hours and the possibility of obtaining an absolute perfect slope for water to flow down, are other plus that make these machines worthy and priceless in this fields.
  • Laser levelling machines for earth-moving:
    the first-rate performance of the Mara levellers permits to move large amount of soil very quickly and with low power. In this way, shorter work hours, lower costs and greater accuracy in creating the horizontal plan and gradient, are attained.
  • Laser levelling machine for sportsground:
    this type of technology can be utilized very well in this field as it makes possible to level even existing areas, repairing slope without replacing the lawn.
  • Laser levelling machines for greenhouses:
    thanks to the accuracy, contained size and easy handling of Mara laser levellers, it is also feasible to work for the maintenance of green spaces. In this way, the right gradient and also a fabulous aesthetic result are secured.
  • Laser grader machines for roads:
    in this field, important results are attained thanks to the capability of the Mara’s laser graders to provide the same job as the motor grader, with less costs and more convenient times. In addition, there are key plus, for example specialized labor is no longer needed, on top to the fact that the use of fine materials is reduced.
