Mara - Niveladoras Laser

Laser leveller blade for horse riding tracks

Mara Laser is a business company that for over 30 years has been examining, 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 outstanding results in different sectors of use: from agricultural soil to sportsground, from building constructions to road excavations, from landscaping to ground scraping.
Mara’s levellers ensure a series of returns and high capacity in more than one situations: from the machine operating velocity, to a total affidability and assurance of the result.

Mara’s technology

The technology used by Mara is what makes it unbeatable, and the results acquired all over the world witness this. Laser and GPS system technologies provide 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 the elements of the laser control system for levelling.
The transmitter is placed on a tripod that examines the natural inclination of the soil and communicates the signal to the receiver, which is instead mounted on the machine itself.
The laser beam, beacuse of its internal characteristics, permits very high accuracy even over long sections of land. After picking up the signal, a technologically perfectioned rotating pentaprism, mounted on these machines, gives back an ideal program for the leveller to follow while operating.
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, even though it could be low or experiences interference.
On the laser leveller, besides, there is a control system to annul external interference. It cuts wind sound, automatically captures the signal and sets the power of the tractor.

GPS system technology

GPS technology, however, is used to set 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 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 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 elasticity of use, mostly when this technology is used to work on large land portions with more than one inclinations, such as agricultural soil and building constructions.

Integrated laser + GPS system

Mara Laser has created and made an integrated system that adds the precision of laser technology with the potential of GPS, proper for tough soil.
The higher accuracy of the laser signal represents the plan within a radius of 1300 meters, while the GPS system communicates the precise spot of the leveller. Hence, the Mara system can set 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 portions that has to be scraped, the loading areas, the section where to begin, and the best way that allows 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 outstanding accuracy and elasticity of the levellers made by Mara Laser assure their use in more than one areas:

  • Laser levelling machines for agriculture:
    Mara’s laser levellers, among the different benefits assure a important increase of the arable land portions. They enable a reduction in the amount of water used, an increased production, a considerable reduction of chemicals used, as well as seeds. The decrease 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 reduced deflections (max 4 mm) and to annul cavities and gaps that would, afterwords, be filled with concrete. The decrease of work times and the possibility of obtaining a perfect slope for water to flow down, are other benefits that make these machines worthy and priceless in this areas.
  • Laser levelling machines for earth-moving:
    the fine 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 accuracy in creating the horizontal plan and inclination, are reached.
  • 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 slope without replacing the lawn.
  • Laser levelling machines for greenhouses:
    thanks to the accuracy, reduced 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 ensured.
  • Laser grader machines for roads:
    in this field, important results are reached thanks to the skills of the Mara’s laser graders to perform 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 necessary, on top to the fact that the use of fine materials is reduced.
