Mara - Laser Levelers

Catalogue

Leveller blade for greenhouses and landscaping

Mara Laser is a business company that for over 30 years has been analyzing, producing and marketing laser and GPS controlled laser levelling machines, calling on buyers in about 30 nations all over the world.
Thanks to GPS and laser control technologies, we can get to significant results in many areas of use: 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 productivity in various 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 unique, 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 levelling machine, 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 tilt of the soil and sends the signal to the receiver, which is instead mounted on the machine itself.
The laser beam, as it is one of its internal characteristics, permits very high accuracy even over long land portions. After picking up the signal, a technologically perfectioned rotating pentaprism, mounted 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, made by Mara Laser, guarantee the levellers will be able to work on any type fo ground and receive the 360° signal, even if it could be low or it goes through interference.
On the laser levelling machine, moreover, there is a control system to remove external interference. It decreases wind sound, automatically intercepts the signal and regulates the power of the tractor.

GPS system technology

GPS technology, however, is used to regulate the position of the laser levelling machine and the height of the blade.
The levellers, that implement this technology, perceive the laser signal from the satellites: even in this situation the planning 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 as it is one of the periodic change of constellation of the satellites.
In any case, the less accuracy is compensated by the wide adaptability of use, mostly 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 made an integrated system that adds the precision of laser technology with the potential of GPS, proper for harsh soil.
The higher accuracy of the laser signal represents the plan within a radius of 1300 meters, while the GPS system communicates the place of the leveller. Therefor, the Mara system can regulate the height of the tractor leveller and the place 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 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 made by Mara Laser ensure their use in various areas:

  • Laser levelling machines for agriculture:
    Mara’s laser levellers, among the many conveniences ensure a important increase of the arable land portions. 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 provides an absolute perfect precision to obtain ground floors with very contained deflections (max 4 mm) and to remove cavities and gaps that would, later, be filled with concrete. The decrease of work hours and the possibility of obtaining an absolute perfect inclinatoin for water to flow down, are other conveniences that make these machines worthy and priceless in this areas.
  • Laser levelling machines for earth-moving:
    the first-rate performance of the Mara levellers permits 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 tilt, are reached.
  • Laser levelling machine for sportsground:
    this type of technology can be used very well in this area as it enables to level even existing areas, repairing soil depressions without replacing the lawn.
  • Laser levelling machines for greenhouses:
    thanks to the accuracy, contained size and easy handling of Mara laser levelling machines, it is also doable to work for the maintenance of green spaces. In this way, the right tilt and also a fabulous aesthetic result are secured.
  • Laser grader machines for roads:
    in this area, important results are reached thanks to the capacity 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 needed, on top to the fact that the use of fine materials is reduced.
