Mara - Niveladoras Laser

Laser leveller blade for agricultural soil

Mara Laser is a business activity that for over 30 years has been examining, producing and marketing laser and GPS controlled laser levellers, calling on clients in about 30 states everywhere in the world.
Thanks to GPS and laser control technologies, it is feasible to achieve outstanding results in many areas of utility: from agricoltural ground to sport facilities, from building constructions to road excavations, from landscaping to ground scraping.
Mara’s levellers ensure a series of advantages and high capacity in various situations: from the machine functioning speed regime, to a total trustworthiness and assurance of the result.

Mara’s technology

The technology used by Mara is what makes it unique, and the results acquired all over the world witness this. Laser and GPS receiver technologies give an unique 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 leveller, the laser beam transmitter and the laser beam receiver are the elements of the laser control system for levelling.
The transmitter is positioned on a tripod that examines the natural tilt of the soil 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, enables very high accuracy even over long sections of land. After picking up the signal, a technologically perfectioned rotating pentaprism, put on these machines, gives back an ideal pianification for the leveller to follow while functioning.
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 work 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, also, there is a control system to annul external interference. It lowers wind sound, automatically intercepts the signal and regulates the power of the tractor.

GPS receiver technology

GPS technology, after all, is used to set the position of the laser leveller and the height of the blade.
The levellers, that implement this technology, obtain the laser signal from the satellites: even in this situation the pianification is illustrated by the signal and reproduced on the soil.
Lately, thanks to technological advancement 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 accuracy is compensated by the wide adaptability of use, in particular when this technology is used to work on large land portions with various inclinations, such as agricoltural ground and building constructions.

Integrated laser + GPS system

Mara Laser has created and manufactured an integrated system that matches the precision of laser technology with the potential of GPS, the right one for tough soil.
The higher accuracy 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 enables to highlight the land portions that has to be scraped, the loading areas, the starting point, and the best route that enables to do the greatest job possible, with both the tractor and the leveller in the right position.
Hence, the operator will have immediate instructions through the constant updating of the data by the system.

Fields of application

The outstanding accuracy and adaptability of the levellers manufactured by Mara Laser assure their use in various areas:

  • Laser levelling machines for agriculture:
    Mara’s laser levellers, among the many benefits assure a important increase of the arable land portions. They enable a reduction in the amount of water used, they can provide more abundant harvest, a considerable reduction of chemicals used, as well as seeds. The decrease in work times, moreover, makes the use of these machines a sure investment.
  • Laser levelling machines for construction:
    Mara Laser provides a perfect precision to obtain ground floors with very contained deflections (max 4 mm) and to annul cavities and gaps that would, later, be filled with concrete. The decrease of work times and the possibility of obtaining a perfect slope for water to flow down, are other benefits that make these machines priceless and incomparable in this areas.
  • Laser levelling machines for earth-moving:
    the fine performance of the Mara levellers enables to move large quantity of soil very quickly and with low power. In this way, shorter work times, lower costs and greater accuracy in creating the horizontal plan and tilt, are achieved.
  • Laser levelling machine for sportsground:
    this type of technology can be utilized very well in this field as it enables to level even existing areas, repairing soil depressions 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 doable to work for the maintenance of green spaces. In this way, the right tilt and also a fabulous aesthetic result are ensured.
  • Laser grader machines for roads:
    in this field, important results are achieved thanks to the capability of the Mara’s laser graders to perform the same job as the motor grader, with poorer costs and more convenient times. In addition, there are important benefits, for example specialized labor is no longer necessary, on top to the fact that the use of fine materials is reduced.
