Mara - Laser Levelers

Catalogue

Levelling machines for greenhouses and landscaping

Mara Laser is a business activity that for 30 years and more has been analyzing, producing and marketing laser and GPS controlled laser levelling machines, calling on buyers in about 30 nations everywhere in the world.
Thanks to GPS and laser control technologies, we can reach important results in many sectors of utility: from agricoltural ground to sportsground, from building constructions to road excavations, from landscaping to soil 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 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 provide an unrivaled performance, in particular when they are combined.

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 placed on a tripod that sees the natural tilt of the soil and sends the signal to the receiver, which is instead mounted on the machine itself.
The laser beam, for its internal characteristics, enables very high preciseness even over long sections of land. After obtaining the signal, a technologically perfectioned rotating pentaprism, mounted on these machines, gives back an ideal pianification 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, manufactured by Mara Laser, guarantee the levellers will be able to move on any kind of ground and receive the 360° signal, even if it could be poor or it goes through interference.
On the leveller, also, there is a control system to annul external interference. It lowers wind sound, 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 adopt this technology, perceive the laser signal from the satellites: even in this situation the pianification is illustrated 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 less accuracy than laser technology: GPS systems are subject to fluctuations for the periodic change of constellation of the satellites.
In any case, the less preciseness is compensated by the wide elasticity of use, in particular when this technology is used to work on large land sections with more than one 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 lays out 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 way that enables to make the best work 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 important preciseness and elasticity of the levellers manufactured by Mara Laser assure their use in more than one fields:

  • Laser levelling machines for agriculture:
    Mara’s laser levellers, among the many conveniences assure a important increase of the arable land sections. They permits 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 times, besides, 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 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 an absolute perfect slope for water to flow down, are other conveniences that make these machines worthy and incomparable in this fields.
  • 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 times, lower costs and greater preciseness in creating the horizontal plan and tilt, are reached.
  • 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 soil depressions without replacing the lawn.
  • Laser levelling machines for greenhouses:
    thanks to the preciseness, reduced size and easy handling of Mara laser levelling machines, it is also feasible to work for the maintenance of green spaces. In this way, the right tilt and also a great aesthetic result are assured.
  • Laser grader machines for roads:
    in this field, important results are reached thanks to the capability of the Mara’s laser graders to provide the same job as the motor grader, with less costs and more convenient times. In addition, there are important conveniences, for example specialized labor is no longer necessary, on top to the fact that the use of fine materials is reduced.
