Mara - Niveladoras Laser

Levelling machines for construction

Mara Laser is a business company that for over 30 years has been examining, making and marketing laser and GPS controlled levellers, calling on clients in about 30 states everywhere in the world.
Thanks to GPS and laser control technologies, it is feasible to achieve considerable results in many areas of use: from agricultural soil to sportsground, from building constructions to road excavations, from landscaping to soil scraping.
Mara’s levellers ensure a series of advantages and high capacity in various situations: from the machine running speed regime, 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 give an unique 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 located on a tripod that sees the natural inclination of the soil and sends the signal to the receiver, which is instead mounted on the machine itself.
The laser beam, for its own characteristics, permits very high preciseness even over long sections of land. After picking up the signal, a technologically perfectioned rotating pentaprism, mounted on these machines, gives back an ideal pianification for the leveller to follow while running.
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, though it could be poor or it is subjected to interference.
On the laser leveller, besides, there is a control system to remove external interference. It lowers wind rumble, automatically captures the signal and sets the power of the tractor.

GPS receiver technology

GPS technology, however, 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 defined 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 reached up, even though this technology offers poorer accuracy than laser technology: GPS systems are subject to fluctuations for the periodic change of constellation of the satellites.
In any case, the poorer preciseness is compensated by the wide elasticity of use, mostly when this technology is used to work on large parts with various inclinations, such as agricultural soil and building constructions.

Integrated laser + GPS system

Mara Laser has created and made an integrated system that connects 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 precise spot of the leveller. Hence, 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 parts that has to be scraped, the loading areas, the section where to begin, and the best way that allows 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 elasticity of the levellers made by Mara Laser secure their use in various areas:

  • Laser levelling machines for agriculture:
    Mara’s laser levellers, among the many plus 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 lowering in work times, moreover, 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 remove cavities and gaps that would, later, be filled with concrete. The lowering of work times and the possibility of obtaining an absolute perfect inclinatoin for water to flow down, are other plus that make these machines worthy and incomparable in this areas.
  • Laser levelling machines for earth-moving:
    the first-rate 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 inclination, are gained.
  • Laser levelling machine for sportsground:
    this type of technology can be used very well in this area 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 inclination and also a fabulous aesthetic result are secured.
  • Laser grader machines for roads:
    in this area, important results are gained thanks to the capacity 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.
