Used grader for horse riding tracks

Mara Laser is a business company that for over 30 years has been examining, making and trading laser and GPS controlled laser levelling machines, calling on clients in about 30 states all over the world.
Thanks to GPS and laser control technologies, it is feasible to achieve significant results in different sectors of use: from agricultural soil to sportsground, from building constructions to road excavations, from landscaping to ground scraping.
Mara’s levellers ensure a series of returns and high capacity in more than one situations: from the machine functioning velocity, to a total trustworthiness 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 receiver technologies give an unique performance, in particular 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 levelling machine, 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 examines the natural tilt of the land and communicates the signal to the receiver, which is instead located on the machine itself.
The laser beam, as it is one of its internal characteristics, permits very high accuracy even over long sections of land. After picking up the signal, a technologically perfectioned rotating pentaprism, located on these machines, gives back an ideal planning for the leveller to follow while functioning.
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 work on any kind of ground and receive the 360° signal, though it could be low or it is subjected to interference.
On the laser levelling machine, besides, there is a control system to annul external interference. It cuts wind sound, automatically reaches the signal and regulates the power of the tractor.

GPS receiver technology

GPS technology, after all, is used to set the position of the laser levelling machine and the height of the blade.
The levellers, that implement this technology, obtain the laser signal from the satellites: even in this situation the planning is represented 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 reached up, 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, in particular when this technology is used to work on large parts with more than one inclinations, such as agricultural soil 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, suitable for harsh land.
The higher accuracy of the laser signal lays out the plan within a radius of 1300 meters, while the GPS system communicates the place of the leveller. Thus, the Mara system can set the height of the tractor leveller and the place of the blade itself.
The creation of the 3D map of the land permits to highlight the parts 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.
Thus, the operator will have prompt instructions through the constant updating of the data by the system.

Fields of application

The significant accuracy and adaptability of the levellers manufactured by Mara Laser ensure their use in more than one fields:

  • Laser levelling machines for agriculture:
    Mara’s laser levellers, among the different conveniences ensure a key increase of the arable parts. 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 provides an absolute perfect precision to obtain ground floors with very contained deflections (max 4 mm) and to annul cavities and gaps that would, later, 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 incomparable and priceless in this fields.
  • Laser levelling machines for earth-moving:
    the first-rate performance of the Mara levellers permits to move large amount 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 tilt, are achieved.
  • 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 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 tilt and also a great aesthetic result are secured.
  • Laser grader machines for roads:
    in this field, important results are achieved thanks to the capability 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 conveniences, for example specialized labor is no longer necessary, besides to the fact that the use of fine materials is reduced.
