Mara - Niveladoras Laser

Used laser leveller blades for tractors

Mara Laser is a business company that for 30 years and more has been examining, producing and marketing laser and GPS controlled laser levelling machines, turning towards buyers in about 30 nations everywhere in the world.
Thanks to GPS and laser control technologies, it is feasible to achieve significant results in different sectors of use: from agricoltural ground to sport facilities, from building constructions to road excavations, from landscaping to ground scraping.
Mara’s levellers ensure a series of returns and high capacity in more than one situations: from the machine functioning velocity, to a total affidability and assurance of the result.

Mara’s technology

The technology used by Mara is what makes it unbeatable, and the results acquired all over the world witness this. Laser and GPS receiver 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 the elements of the laser control system for levelling.
The transmitter is placed on a tripod that observes the natural gradient of the land and communicates the signal to the receiver, which is instead mounted on the machine itself.
The laser beam, beacuse of its own characteristics, permits very high accuracy even over long sections of land. After getting the signal, a technologically perfectioned rotating pentaprism, mounted on these machines, gives back an ideal planning for the leveller to follow while functioning.
The receiver also has an important role, 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 move on any kind of soil and receive the 360° signal, even if it could be poor or experiences interference.
On the laser levelling machine, also, there is a control system to remove external interference. It lowers wind rumble, automatically captures the signal and regulates the power of the tractor.

GPS receiver technology

GPS technology, however, 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 planning is represented by the signal and reproduced on the land.
Nowadays, 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 beacuse of the periodic change of constellation of the satellites.
In any case, the poorer accuracy is compensated by the wide elasticity 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 made an integrated system that matches the precision of laser technology with the potential of GPS, perfect for tough land.
The higher accuracy of the laser signal represents the plan within a radius of 1300 meters, while the GPS system communicates the place of the leveller. Therefor, the Mara system can set the height of the tractor leveller and the place of the blade itself.
The creation of the 3D map of the land permits to highlight the parts that has to be scraped, the loading areas, the section where to begin, and the best route that allows to do the greatest job 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 significant accuracy and elasticity of the levellers made by Mara Laser secure their use in more than one areas:

  • Laser levelling machines for agriculture:
    Mara’s laser levellers, among the different plus secure a key increase of the arable parts. They enable a reduction in the amount of water used, an increased production, a less use of chemicals, as well as seeds. The decrease in work hours, furthermore, makes the use of these machines a sure investment.
  • Laser levelling machines for construction:
    Mara Laser gives a perfect precision to obtain ground floors with very reduced deflections (max 4 mm) and to remove cavities and gaps that would, later, be filled with concrete. The decrease of work hours and the possibility of obtaining a perfect slope for water to flow down, are other plus that make these machines priceless and incomparable in this areas.
  • Laser levelling machines for earth-moving:
    the superbe performance of the Mara levellers permits to move large quantity of soil very quickly and with low power. In this way, shorter work hours, lower costs and greater accuracy 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 sectors, repairing soil depressions without replacing the lawn.
  • Laser levelling machines for greenhouses:
    thanks to the accuracy, reduced size and easy handling of Mara laser levelling machines, 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 secured.
  • Laser grader machines for roads:
    in this field, important results are attained thanks to the capability 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 plus, for example specialized labor is no longer necessary, besides to the fact that the use of fine materials is reduced.
