Mara - Laser Levelers

Catalogue

Used grader for earth-moving

Mara Laser is a business activity that for over 30 years has been analyzing, making and trading laser and GPS controlled levellers, calling on buyers in about 30 states all over the world.
Thanks to GPS and laser control technologies, it is feasible to achieve important results in different sectors of utility: from agricoltural ground to sportsground, 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 functioning speed regime, to a total affidability and guarantee of the final success.

Mara’s technology

The technology used by Mara is what makes it unbeatable, and the results obtained all over the world are proof of 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 continually 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 put on a tripod that examines the natural gradient of the soil and sends the signal to the receiver, which is instead positioned on the machine itself.
The laser beam, for its own 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, gives back an ideal planning for the leveller to follow while functioning.
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, though it could be low or it is subjected to interference.
On the leveller, also, there is a control system to annul external interference. It lowers wind sound, automatically intercepts the signal and settles the power of the tractor.

GPS system technology

GPS technology, after all, is used to settle 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 planning is represented by the signal and reproduced on the soil.
Nowadays, thanks to technological progress and the use of dedicated software, an accuracy of ± 10 mm has been reached up, 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 preciseness is compensated by the wide elasticity of use, in particular when this technology is used to work on large land portions with various inclinations, such as agricoltural ground and building constructions.

Integrated laser + GPS system

Mara Laser has produced and manufactured an integrated system that matches the precision of laser technology with the potential of GPS, suitable for harsh soil.
The higher preciseness of the laser signal shows the plan within a radius of 1300 meters, while the GPS system communicates the precise spot of the leveller. Hence, 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 portions that has to be scraped, the loading areas, the section where to begin, and the best route that allows to do the greatest job possible, with both the tractor and the leveller in the right position.
Hence, the operator will have instant instructions through the constant updating of the data by the system.

Fields of application

The important preciseness and elasticity of the levellers manufactured by Mara Laser ensure their use in various areas:

  • Laser levelling machines for agriculture:
    Mara’s laser levellers, among the different conveniences ensure a key increase of the arable land portions. 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 times, besides, makes the use of these machines a sure investment.
  • Laser levelling machines for construction:
    Mara Laser provides an absolute perfect precision to obtain ground floors with very contained deflections (max 4 mm) and to annul cavities and gaps that would, later, be filled with concrete. The lowering of work times and the possibility of obtaining an absolute perfect slope for water to flow down, are other conveniences that make these machines worthy 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 times, lower costs and greater preciseness in creating the horizontal plan and gradient, are achieved.
  • Laser levelling machine for sportsground:
    this type of technology can be utilized 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 secured.
  • Laser grader machines for roads:
    in this area, important results are achieved 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 key conveniences, for example specialized labor is no longer needed, on top to the fact that the use of fine materials is reduced.
