Laser levelling machine for roads

Mara Laser is a business activity that for over 30 years has been analyzing, making and trading laser and GPS controlled levellers, calling on buyers in about 30 nations everywhere in the world.
Thanks to GPS and laser control technologies, we can reach considerable results in different areas of utility: from agricoltural ground to sport facilities, from building constructions to road excavations, from landscaping to soil scraping.
Mara’s levellers ensure a series of returns and high capacity in more than one situations: from the machine operating velocity, 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 testify 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 leveller, the laser beam transmitter and the laser beam receiver are parts of the laser control system for levelling.
The transmitter is positioned on a tripod that sees the natural tilt of the land and communicates the signal to the receiver, which is instead put on the machine itself.
The laser beam, for its own characteristics, enables very high preciseness even over long sections of land. After getting the signal, a technologically perfectioned rotating pentaprism, put on these machines, returns an ideal planning 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 it goes through interference.
On the leveller, moreover, there is a control system to annul external interference. It lowers wind sound, automatically intercepts the signal and settles the power of the tractor.

GPS receiver technology

GPS technology, however, is used to settle the position of the leveller and the height of the blade.
The levellers, that adopt this technology, perceive the laser signal from the satellites: even in this situation the planning is illustrated by the signal and reproduced on the land.
Lately, thanks to technological progress and the use of dedicated software, an accuracy of ± 10 mm has been obtained, even though this technology offers less accuracy than laser technology: GPS systems are subject to fluctuations for the periodic change of constellation of the satellites.
In any case, the less preciseness is compensated by the wide adaptability of use, in particular when this technology is used to work on large parts with more than one inclinations, such as agricoltural ground and building constructions.

Integrated laser + GPS system

Mara Laser has produced and manufactured an integrated system that adds the precision of laser technology with the potential of GPS, proper for harsh land.
The higher preciseness of the laser signal shows the plan within a radius of 1300 meters, while the GPS system communicates the place of the leveller. Therefor, the Mara system can settle the height of the tractor leveller and the place of the blade itself.
The creation of the 3D map of the land enables to highlight the parts 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 considerable preciseness and adaptability of the levellers manufactured by Mara Laser secure their use in more than one fields:

  • Laser levelling machines for agriculture:
    Mara’s laser levellers, among the different conveniences secure a key increase of the arable parts. 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, furthermore, makes the use of these machines a sure investment.
  • Laser levelling machines for construction:
    Mara Laser provides an absolute 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 an absolute perfect slope for water to flow down, are other conveniences that make these machines incomparable and incomparable in this fields.
  • Laser levelling machines for earth-moving:
    the first-rate performance of the Mara levellers enables to move large amount of soil very quickly and with low power. In this way, shorter work times, lower costs and greater preciseness in creating the horizontal plan and tilt, are gained.
  • Laser levelling machine for sportsground:
    this type of technology can be utilized very well in this area as it enables to level even existing areas, repairing slope without replacing the lawn.
  • Laser levelling machines for greenhouses:
    thanks to the preciseness, contained size and easy handling of Mara levellers, it is also doable to work for the maintenance of green spaces. In this way, the right tilt and also a great aesthetic result are ensured.
  • Laser grader machines for roads:
    in this area, important results are gained thanks to the capability of the Mara’s laser graders to perform the same job as the motor grader, with less costs and more convenient times. In addition, there are key conveniences, for example specialized labor is no longer needed, besides to the fact that the use of fine materials is reduced.
