Mara - Laser Levelers

Catalogue

Used grader for construction

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 buyers in about 30 states everywhere in the world.
Thanks to GPS and laser control technologies, it is feasible to achieve considerable results in many sectors of utility: 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 more than one situations: from the machine operating speed regime, 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 obtained all over the world testify this. Laser and GPS system technologies give an unrivaled performance, mostly 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 placed on a tripod that observes the natural gradient of the land and sends the signal to the receiver, which is instead positioned on the machine itself.
The laser beam, as it is one of its internal characteristics, enables very high accuracy even over long sections of land. After picking up the signal, a technologically perfectioned rotating pentaprism, positioned on these machines, gives back an ideal pianification 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 kind of ground and receive the 360° signal, though it could be low or experiences interference.
On the leveller, also, there is a control system to remove external interference. It lowers wind rumble, automatically reaches the signal and sets the power of the tractor.

GPS system technology

GPS technology, after all, is used to regulate the position of the leveller and the height of the blade.
The levellers, that adopt this technology, obtain the laser signal from the satellites: even in this situation the pianification is defined by the signal and reproduced on the land.
Nowadays, 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 as it is one of 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 more than one inclinations, such as agricultural soil and building constructions.

Integrated laser + GPS system

Mara Laser has created 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 starting point, and the best route that enables to do the greatest job possible, with both the tractor and the leveller in the right position.
Therefor, the operator will have prompt 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 more than one areas:

  • Laser levelling machines for agriculture:
    Mara’s laser levellers, among the many conveniences assure a key increase of the arable land sections. They permits 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 hours, moreover, makes the use of these machines a sure investment.
  • Laser levelling machines for construction:
    Mara Laser gives 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 decrease of work hours and the possibility of obtaining a perfect inclinatoin for water to flow down, are other conveniences that make these machines priceless and priceless in this areas.
  • Laser levelling machines for earth-moving:
    the fine 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 gradient, are gained.
  • Laser levelling machine for sportsground:
    this type of technology can be used very well in this field as it makes possible to level even existing sectors, repairing soil depressions 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 doable to work for the maintenance of green spaces. In this way, the right gradient and also a great aesthetic result are assured.
  • Laser grader machines for roads:
    in this field, important results are gained thanks to the capability 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 key conveniences, for example specialized labor is no longer needed, on top to the fact that the use of fine materials is reduced.
