Mara - Laser Levelers

Catalogue

Used laser leveller blades for roads

Mara Laser is a business company 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 outstanding results in many areas of utility: from agricultural soil 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 more than one situations: from the machine functioning velocity, to a total trustworthiness 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 unrivaled 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 examines the natural inclination of the land and sends the signal to the receiver, which is instead positioned on the machine itself.
The laser beam, beacuse of its internal characteristics, permits very high accuracy even over long sections of land. After getting the signal, a technologically perfectioned rotating pentaprism, positioned on these machines, gives back 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, 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, also, there is a control system to remove external interference. It decreases wind rumble, automatically intercepts the signal and sets the power of the tractor.

GPS system technology

GPS technology, however, is used to settle the position of the laser leveller and the height of the blade.
The levellers, that implement this technology, obtain the laser signal from the satellites: even in this situation the pianification is defined 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 less accuracy than laser technology: GPS systems are subject to fluctuations beacuse 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 sections with more than one inclinations, such as agricultural soil and building constructions.

Integrated laser + GPS system

Mara Laser has produced and manufactured an integrated system that adds the precision of laser technology with the potential of GPS, perfect for harsh land.
The higher accuracy of the laser signal represents 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 land permits to highlight the land sections 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 immediate instructions through the constant updating of the data by the system.

Fields of application

The outstanding accuracy and adaptability of the levellers manufactured by Mara Laser secure their use in more than one areas:

  • Laser levelling machines for agriculture:
    Mara’s laser levellers, among the many benefits secure a key 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 lowering in work times, besides, makes the use of these machines a sure investment.
  • Laser levelling machines for construction:
    Mara Laser gives 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 lowering of work times and the possibility of obtaining a perfect slope for water to flow down, are other benefits that make these machines priceless 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 times, lower costs and greater accuracy in creating the horizontal plan and inclination, are reached.
  • Laser levelling machine for sportsground:
    this type of technology can be used very well in this field as it makes possible 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 feasible 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 reached thanks to the capacity of the Mara’s laser graders to perform the same job as the motor grader, with less costs and more convenient times. In addition, there are key benefits, for example specialized labor is no longer needed, on top to the fact that the use of fine materials is reduced.
