Mara - Niveladoras Laser

GPS laser levellers for agricultural soil

Mara Laser is a business activity that for over 30 years has been analyzing, making and trading laser and GPS controlled laser levelling machines, calling on clients in about 30 nations all over the world.
Thanks to GPS and laser control technologies, we can get to outstanding results in different sectors of use: 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 capacity in various situations: from the machine running speed regime, to a total trustworthiness 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 receiver technologies provide an unique performance, in particular when they are used together.

Laser technology

Laser technology is applied to the levellers in a way that without stopping 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 located on a tripod that sees the natural inclination of the soil and communicates the signal to the receiver, which is instead put 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, put on these machines, returns an ideal program for the leveller to follow while running.
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 type fo ground and receive the 360° signal, though it could be low or it is subjected to interference.
On the leveller, also, there is a control system to remove external interference. It cuts wind rumble, automatically reaches the signal and regulates the power of the tractor.

GPS receiver technology

GPS technology, however, is used to regulate 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 program 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 reached up, 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 elasticity of use, in particular when this technology is used to work on large land sections with various 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 precise spot of the leveller. Thus, the Mara system can regulate 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 sections 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.
Thus, the operator will have instant instructions through the constant updating of the data by the system.

Fields of application

The outstanding preciseness and elasticity of the levellers manufactured 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 sections. 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 a perfect precision to obtain ground floors with very contained deflections (max 4 mm) and to remove cavities and gaps that would, afterwords, be filled with concrete. The lowering of work times and the possibility of obtaining a perfect inclinatoin 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 first-rate performance of the Mara levellers permits 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 inclination, are gained.
  • 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 preciseness, contained 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 inclination and also a fabulous aesthetic result are secured.
  • Laser grader machines for roads:
    in this field, important results are gained thanks to the skills of the Mara’s laser graders to provide 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, besides to the fact that the use of fine materials is reduced.
