Mara - Niveladoras Laser

Used graders for greenhouses and landscaping

Mara Laser is a business company that for over 30 years has been analyzing, making and marketing laser and GPS controlled laser levellers, calling on clients 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 agricultural soil to sport facilities, 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 operating speed regime, to a total trustworthiness 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 testify this. Laser and GPS receiver technologies give an unrivaled 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 parts of the laser control system for levelling.
The transmitter is located on a tripod that sees the natural inclination of the land and sends the signal to the receiver, which is instead put on the machine itself.
The laser beam, for its own characteristics, enables very high accuracy even over long sections of land. After picking up the signal, a technologically perfectioned rotating pentaprism, put on these machines, returns an ideal planning for the leveller to follow while operating.
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, even 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 decreases wind rumble, automatically intercepts the signal and regulates the power of the tractor.

GPS receiver technology

GPS technology, after all, is used to regulate the position of the laser leveller and the height of the blade.
The levellers, that implement this technology, get the laser signal from the satellites: even in this situation the planning is represented by the signal and reproduced on the land.
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 for the periodic change of constellation of the satellites.
In any case, the minor accuracy is compensated by the wide adaptability of use, mostly 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 produced and manufactured an integrated system that connects the precision of laser technology with the potential of GPS, the right one 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 location of the leveller. Therefor, the Mara system can regulate 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 point where to start, and the best route that enables 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 significant 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 key increase of the arable land sections. They enable a reduction in the amount of water used, they can provide more abundant harvest, a less use of chemicals, as well as seeds. The decrease in work hours, moreover, 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 decrease of work hours and the possibility of obtaining an absolute perfect slope for water to flow down, are other benefits that make these machines incomparable and incomparable in this areas.
  • Laser levelling machines for earth-moving:
    the first-rate performance of the Mara levellers enables 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 inclination, are attained.
  • Laser levelling machine for sportsground:
    this type of technology can be utilized very well in this field as it makes possible to level even existing sectors, repairing slope without replacing the lawn.
  • Laser levelling machines for greenhouses:
    thanks to the accuracy, contained size and easy handling of Mara laser 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 field, important results are attained thanks to the capacity 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 key benefits, for example specialized labor is no longer necessary, besides to the fact that the use of fine materials is reduced.
