Mara - Niveladoras Laser

GPS laser levellers for earth-moving

Mara Laser is a business company that for 30 years and more has been examining, producing and marketing laser and GPS controlled levellers, turning towards buyers in about 30 nations all over the world.
Thanks to GPS and laser control technologies, we can reach significant results in many sectors of use: 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 running speed regime, to a total affidability and guarantee of the final success.

Mara’s technology

The technology used by Mara is what makes it unique, and the results obtained all over the world are proof of 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 placed on a tripod that sees the natural gradient of the land and communicates the signal to the receiver, which is instead positioned on the machine itself.
The laser beam, for its internal characteristics, enables very high preciseness even over long sections of land. After picking up the signal, a technologically perfectioned rotating pentaprism, positioned 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, made by Mara Laser, guarantee the levellers will be able to work on any kind of soil and receive the 360° signal, even if it could be poor or it goes through interference.
On the laser leveller, besides, there is a control system to remove external interference. It decreases wind rumble, automatically intercepts the signal and sets the power of the tractor.

GPS receiver technology

GPS technology, however, is used to set the position of the laser leveller and the height of the blade.
The levellers, that adopt this technology, get the laser signal from the satellites: even in this situation the program is represented by the signal and reproduced on the land.
Nowadays, thanks to technological advancement 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 for the periodic change of constellation of the satellites.
In any case, the less preciseness is compensated by the wide elasticity of use, mostly when this technology is used to work on large land sections with various inclinations, such as agricoltural ground 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, proper for harsh land.
The higher preciseness of the laser signal shows the plan within a radius of 1300 meters, while the GPS system communicates the location of the leveller. Hence, the Mara system can set the height of the tractor leveller and the location of the blade itself.
The creation of the 3D map of the land enables to highlight the land sections that has to be scraped, the loading areas, the starting point, and the best way that enables to make the best work possible, with both the tractor and the leveller in the right position.
Hence, the operator will have immediate instructions through the constant updating of the data by the system.

Fields of application

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

  • Laser levelling machines for agriculture:
    Mara’s laser levellers, among the many benefits assure a important increase of the arable land sections. They enable a reduction in the amount of water used, an increased production, a less use of chemicals, as well as seeds. The lowering in work hours, besides, makes the use of these machines a sure investment.
  • Laser levelling machines for construction:
    Mara Laser gives an absolute 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 hours and the possibility of obtaining an absolute perfect inclinatoin for water to flow down, are other benefits that make these machines priceless and incomparable in this areas.
  • Laser levelling machines for earth-moving:
    the fine performance of the Mara levellers enables to move large amount of soil very quickly and with low power. In this way, shorter work hours, lower costs and greater preciseness in creating the horizontal plan and gradient, are gained.
  • Laser levelling machine for sportsground:
    this type of technology can be used very well in this area as it makes possible 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 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 area, 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 important benefits, for example specialized labor is no longer needed, on top to the fact that the use of fine materials is reduced.
