Mara - Laser Levelers

Catalogue

Used leveller blades for roads

Mara Laser is a business activity that for over 30 years has been analyzing, producing and marketing laser and GPS controlled levellers, turning towards buyers in about 30 states everywhere in the world.
Thanks to GPS and laser control technologies, we can reach considerable results in different 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 returns and high productivity in more than one situations: from the machine functioning velocity, 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 obtained all over the world are proof of this. Laser and GPS system technologies give an unique performance, mostly when they are combined.

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 put on a tripod that observes the natural tilt of the soil and sends the signal to the receiver, which is instead put on the machine itself.
The laser beam, beacuse of its internal characteristics, enables very high accuracy even over long sections of land. After getting the signal, a technologically perfectioned rotating pentaprism, put on these machines, returns an ideal pianification 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, made by Mara Laser, guarantee the levellers will be able to move on any type fo ground and receive the 360° signal, even if it could be low or experiences interference.
On the leveller, moreover, there is a control system to annul external interference. It decreases wind rumble, automatically intercepts the signal and regulates 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, perceive the laser signal from the satellites: even in this situation the pianification is illustrated by the signal and reproduced on the soil.
Nowadays, thanks to technological advancement and the use of dedicated software, an accuracy of ± 10 mm has been reached up, even though this technology offers poorer accuracy than laser technology: GPS systems are subject to fluctuations beacuse of the periodic change of constellation of the satellites.
In any case, the poorer accuracy is compensated by the wide adaptability of use, mostly when this technology is used to work on large land portions with more than one inclinations, such as agricoltural ground and building constructions.

Integrated laser + GPS system

Mara Laser has created and made an integrated system that connects the precision of laser technology with the potential of GPS, perfect for tough soil.
The higher accuracy 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 portions that has to be scraped, the loading areas, the point where to start, and the best way that allows to make the best work possible, with both the tractor and the leveller in the right position.
Therefor, the operator will have instant instructions through the constant updating of the data by the system.

Fields of application

The considerable accuracy and adaptability of the levellers made by Mara Laser secure their use in more than one fields:

  • Laser levelling machines for agriculture:
    Mara’s laser levellers, among the different plus secure a important increase of the arable land portions. They permits 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 decrease in work hours, 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 contained deflections (max 4 mm) and to annul 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 plus that make these machines worthy and priceless in this fields.
  • Laser levelling machines for earth-moving:
    the first-rate performance of the Mara levellers enables to move large amount 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 attained.
  • 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 areas, repairing soil depressions without replacing the lawn.
  • Laser levelling machines for greenhouses:
    thanks to the accuracy, contained size and easy handling of Mara levellers, 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 attained thanks to the capability of the Mara’s laser graders to perform the same job as the motor grader, with poorer costs and more convenient times. In addition, there are important plus, for example specialized labor is no longer necessary, on top to the fact that the use of fine materials is reduced.
