GPS grader for earth-moving

Mara Laser is a business company that for 30 years and more has been analyzing, making and trading laser and GPS controlled laser levellers, turning towards clients in about 30 nations everywhere in the world.
Thanks to GPS and laser control technologies, we can reach outstanding results in different sectors of use: from agricoltural ground to sport facilities, from building constructions to road excavations, from landscaping to soil scraping.
Mara’s levellers ensure a series of advantages and high capacity in more than one situations: from the machine operating speed regime, to a total affidability and assurance of the result.

Mara’s technology

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

Laser technology

Laser technology is applied to the levellers in a way that continually synchronize the height of the blade.
The laser levelling machine, the laser beam transmitter and the laser beam receiver are parts of the laser control system for levelling.
The transmitter is located on a tripod that sees the natural gradient of the soil and sends 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 preciseness even over long sections of land. After obtaining the signal, a technologically perfectioned rotating pentaprism, put on these machines, gives back an ideal program for the leveller to follow while operating.
The receiver also plays a very important part, because it correctly reads the laser light received from the transmitter, through special photodiodes. The receivers, manufactured by Mara Laser, guarantee the levellers will be able to move on any kind of soil and receive the 360° signal, even if it could be low or experiences interference.
On the laser levelling machine, also, there is a control system to remove external interference. It decreases wind sound, automatically captures the signal and regulates the power of the tractor.

GPS system technology

GPS technology, after all, is used to set the position of the laser levelling machine and the height of the blade.
The levellers, that implement this technology, obtain the laser signal from the satellites: even in this situation the program is illustrated by the signal and reproduced on the soil.
Lately, thanks to technological progress and the use of dedicated software, an accuracy of ± 10 mm has been obtained, even though this technology offers poorer 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 poorer preciseness is compensated by the wide adaptability of use, in particular when this technology is used to work on large land sections with more than one inclinations, such as agricoltural ground and building constructions.

Integrated laser + GPS system

Mara Laser has created and manufactured an integrated system that adds the precision of laser technology with the potential of GPS, perfect for harsh soil.
The higher preciseness of the laser signal represents the plan within a radius of 1300 meters, while the GPS system communicates the location of the leveller. Hence, the Mara system can set the height of the tractor leveller and the location of the blade itself.
The creation of the 3D map of the soil permits to highlight the land sections that has to be scraped, the loading areas, the point where to start, and the best route that enables to make the best work possible, with both the tractor and the leveller in the right position.
Hence, the operator will have prompt instructions through the constant updating of the data by the system.

Fields of application

The outstanding preciseness and adaptability of the levellers manufactured by Mara Laser secure their use in more than one areas:

  • Laser levelling machines for agriculture:
    Mara’s laser levellers, among the different conveniences secure a key increase of the arable land sections. They enable a reduction in the amount of water used, they can provide more abundant harvest, a less use of chemicals, as well as seeds. The decrease in work hours, moreover, 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 decrease of work hours and the possibility of obtaining an absolute perfect inclinatoin for water to flow down, are other conveniences that make these machines priceless and priceless in this areas.
  • Laser levelling machines for earth-moving:
    the fine 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 preciseness in creating the horizontal plan and gradient, are attained.
  • Laser levelling machine for sportsground:
    this type of technology can be used very well in this area as it enables to level even existing sectors, repairing soil depressions without replacing the lawn.
  • Laser levelling machines for greenhouses:
    thanks to the preciseness, contained size and easy handling of Mara laser levellers, it is also doable 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 area, important results are attained thanks to the capacity of the Mara’s laser graders to provide the same job as the motor grader, with poorer costs and more convenient times. In addition, there are key conveniences, for example specialized labor is no longer needed, on top to the fact that the use of fine materials is reduced.
