Mara - Laser Levelers

Catalogue

Laser leveller blade for greenhouses and landscaping

Mara Laser is a business company that for over 30 years has been examining, producing and trading laser and GPS controlled levellers, turning towards buyers in about 30 nations everywhere in the world.
Thanks to GPS and laser control technologies, we can reach significant results in different areas of utility: from agricoltural ground to sport courts, from building constructions to road excavations, from landscaping to soil scraping.
Mara’s levellers ensure a series of returns and high productivity in various situations: from the machine operating velocity, to a total trustworthiness and certainty 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 unrivaled performance, mostly 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 placed on a tripod that observes the natural gradient of the soil and sends the signal to the receiver, which is instead mounted on the machine itself.
The laser beam, beacuse of its internal characteristics, permits very high preciseness even over long sections of land. After getting the signal, a technologically perfectioned rotating pentaprism, mounted on these machines, returns an ideal pianification 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, made by Mara Laser, guarantee the levellers will be able to work on any kind of ground and receive the 360° signal, even if it could be poor or experiences interference.
On the laser leveller, besides, there is a control system to annul external interference. It lowers wind rumble, automatically captures the signal and sets the power of the tractor.

GPS receiver technology

GPS technology, after all, is used to settle the position of the laser leveller and the height of the blade.
The levellers, that adopt 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.
Nowadays, thanks to technological advancement 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 beacuse of the periodic change of constellation of the satellites.
In any case, the less preciseness is compensated by the wide adaptability of use, mostly 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 made an integrated system that matches the precision of laser technology with the potential of GPS, suitable for harsh soil.
The higher preciseness of the laser signal shows the plan within a radius of 1300 meters, while the GPS system communicates the precise spot of the leveller. Therefor, the Mara system can settle the height of the tractor leveller and the precise spot of the blade itself.
The creation of the 3D map of the soil permits to highlight the land portions that has to be scraped, the loading areas, the starting point, and the best way that allows to do the greatest job possible, with both the tractor and the leveller in the right position.
Therefor, the operator will have prompt instructions through the constant updating of the data by the system.

Fields of application

The significant preciseness and adaptability of the levellers made by Mara Laser secure their use in various areas:

  • Laser levelling machines for agriculture:
    Mara’s laser levellers, among the different conveniences secure a key increase of the arable land portions. They permits 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 lowering 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 lowering of work times and the possibility of obtaining an absolute perfect slope for water to flow down, are other conveniences that make these machines worthy and priceless in this areas.
  • Laser levelling machines for earth-moving:
    the fine performance of the Mara levellers permits to move large quantity 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 gradient, are attained.
  • Laser levelling machine for sportsground:
    this type of technology can be used 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 preciseness, contained size and easy handling of Mara 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 assured.
  • Laser grader machines for roads:
    in this field, important results are attained 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 necessary, on top to the fact that the use of fine materials is reduced.
