Mara - Niveladoras Laser

Leveller blades for construction

Mara Laser is a business company that for 30 years and more has been analyzing, making and marketing laser and GPS controlled levellers, calling on buyers in about 30 states everywhere in the world.
Thanks to GPS and laser control technologies, we can reach considerable results in different areas of use: from agricultural soil to sport facilities, from building constructions to road excavations, from landscaping to soil scraping.
Mara’s levellers ensure a series of advantages and high productivity in various situations: from the machine running velocity, to a total affidability and certainty of the result.

Mara’s technology

The technology used by Mara is what makes it unique, and the results acquired all over the world witness 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 without stopping synchronize the height of the blade.
The 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 gradient of the soil and communicates the signal to the receiver, which is instead positioned on the machine itself.
The laser beam, beacuse of its own characteristics, enables very high accuracy even over long land portions. After picking up the signal, a technologically perfectioned rotating pentaprism, positioned on these machines, gives back 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 work on any type fo ground and receive the 360° signal, even though it could be poor or it is subjected to interference.
On the leveller, also, there is a control system to remove external interference. It decreases wind rumble, automatically reaches the signal and settles the power of the tractor.

GPS system technology

GPS technology, however, is used to settle the position of the leveller and the height of the blade.
The levellers, that implement this technology, perceive the laser signal from the satellites: even in this situation the program 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 obtained, even though this technology offers minor accuracy than laser technology: GPS systems are subject to fluctuations beacuse of the periodic change of constellation of the satellites.
In any case, the minor accuracy is compensated by the wide adaptability 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 matches the precision of laser technology with the potential of GPS, perfect for tough soil.
The higher accuracy of the laser signal shows the plan within a radius of 1300 meters, while the GPS system communicates the precise spot of the leveller. Therefor, 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 enables to highlight the land sections that has to be scraped, the loading areas, the starting point, and the best route that allows to make the best work possible, with both the tractor and the leveller in the right position.
Therefor, the operator will have immediate instructions through the constant updating of the data by the system.

Fields of application

The considerable accuracy and adaptability of the levellers manufactured by Mara Laser assure their use in various areas:

  • Laser levelling machines for agriculture:
    Mara’s laser levellers, among the different benefits assure a important increase of the arable land sections. 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 hours, furthermore, 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 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 area as it enables to level even existing areas, repairing soil depressions without replacing the lawn.
  • Laser levelling machines for greenhouses:
    thanks to the accuracy, 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 gradient 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 benefits, for example specialized labor is no longer needed, besides to the fact that the use of fine materials is reduced.
