Mara - Laser Levelers

Catalogue

Grader for tractors

Mara Laser is a business company that for 30 years and more has been examining, producing and trading laser and GPS controlled levellers, calling on clients in about 30 nations everywhere in the world.
Thanks to GPS and laser control technologies, we can get to considerable results in many sectors of utility: from agricultural soil to sport courts, from building constructions to road excavations, from landscaping to ground scraping.
Mara’s levellers ensure a series of advantages and high productivity in more than one situations: from the machine operating velocity, to a total affidability and certainty of the result.

Mara’s technology

The technology used by Mara is what makes it unbeatable, and the results obtained all over the world testify this. Laser and GPS system 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 levelling machine, 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 examines the natural tilt of the soil and sends the signal to the receiver, which is instead mounted on the machine itself.
The laser beam, as it is one of its internal characteristics, enables very high preciseness even over long land portions. After getting the signal, a technologically perfectioned rotating pentaprism, mounted on these machines, gives back an ideal pianification for the leveller to follow while operating.
The receiver also has an important role, 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 laser levelling machine, also, there is a control system to annul external interference. It lowers wind sound, automatically reaches the signal and sets the power of the tractor.

GPS system technology

GPS technology, however, is used to settle the position of the laser levelling machine and the height of the blade.
The levellers, that adopt this technology, perceive 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 progress and the use of dedicated software, an accuracy of ± 10 mm has been obtained, even though this technology offers minor 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 minor 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 agricultural soil 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, the right one for tough soil.
The higher preciseness of the laser signal lays out the plan within a radius of 1300 meters, while the GPS system communicates the location of the leveller. Hence, the Mara system can settle 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 parts that has to be scraped, the loading areas, the section where to begin, and the best way that enables to do the greatest job 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 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 many conveniences secure a important increase of the arable parts. They permits 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 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 inclinatoin for water to flow down, are other conveniences that make these machines priceless and priceless 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 attained.
  • Laser levelling machine for sportsground:
    this type of technology can be utilized very well in this area as it makes possible to level even existing sectors, 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 secured.
  • Laser grader machines for roads:
    in this area, important results are attained thanks to the skills of the Mara’s laser graders to provide the same job as the motor grader, with minor costs and more convenient times. In addition, there are important conveniences, for example specialized labor is no longer needed, besides to the fact that the use of fine materials is reduced.
