Mara - Laser Levelers

Catalogue

Grader for roads

Mara Laser is a business company that for over 30 years has been analyzing, making 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 outstanding results in different areas of use: from agricoltural ground 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 various situations: from the machine operating speed regime, to a total trustworthiness 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 provide 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 laser leveller, the laser beam transmitter and the laser beam receiver are parts of the laser control system for levelling.
The transmitter is positioned on a tripod that observes the natural inclination of the land and communicates the signal to the receiver, which is instead put on the machine itself.
The laser beam, beacuse of its own characteristics, permits very high accuracy even over long sections of land. After obtaining the signal, a technologically perfectioned rotating pentaprism, put on these machines, returns an ideal planning 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 soil and receive the 360° signal, though it could be low or it goes through interference.
On the laser leveller, moreover, there is a control system to remove external interference. It lowers wind rumble, 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 laser 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 planning is illustrated by the signal and reproduced on the land.
Lately, thanks to technological advancement 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 beacuse of the periodic change of constellation of the satellites.
In any case, the minor accuracy is compensated by the wide elasticity 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 created and manufactured an integrated system that connects the precision of laser technology with the potential of GPS, proper for tough land.
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. 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 land 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 do the greatest job possible, with both the tractor and the leveller in the right position.
Hence, the operator will have immediate instructions through the constant updating of the data by the system.

Fields of application

The outstanding accuracy and elasticity of the levellers manufactured by Mara Laser secure their use in various fields:

  • Laser levelling machines for agriculture:
    Mara’s laser levellers, among the different plus secure a important increase of the arable land portions. They enable a reduction in the amount of water used, an increased production, 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 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 plus that make these machines priceless and priceless in this fields.
  • Laser levelling machines for earth-moving:
    the superbe 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 inclination, are achieved.
  • Laser levelling machine for sportsground:
    this type of technology can be used very well in this field as it enables to level even existing areas, repairing slope 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 inclination and also a great aesthetic result are ensured.
  • Laser grader machines for roads:
    in this field, 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 important plus, for example specialized labor is no longer necessary, besides to the fact that the use of fine materials is reduced.
