Mara - Laser Levelers

Catalogue

Used leveller blade for earth-moving

Mara Laser is a business company that for 30 years and more has been analyzing, making and marketing laser and GPS controlled levellers, turning towards buyers in about 30 states all over the world.
Thanks to GPS and laser control technologies, we can reach outstanding results in many sectors of utility: 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 productivity in various situations: from the machine running speed regime, to a total affidability and certainty 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, in particular 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 leveller, 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 observes the natural gradient of the land and communicates the signal to the receiver, which is instead positioned on the machine itself.
The laser beam, for its internal characteristics, enables very high preciseness 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 running.
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 work on any kind of soil and receive the 360° signal, though it could be low or it goes through interference.
On the leveller, also, there is a control system to annul 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 regulate the position of the leveller and the height of the blade.
The levellers, that adopt this technology, obtain the laser signal from the satellites: even in this situation the pianification is illustrated by the signal and reproduced on the land.
Lately, thanks to technological progress and the use of dedicated software, an accuracy of ± 10 mm has been reached up, even though this technology offers minor accuracy than laser technology: GPS systems are subject to fluctuations for the periodic change of constellation of the satellites.
In any case, the minor preciseness is compensated by the wide elasticity of use, in particular when this technology is used to work on large land portions with various inclinations, such as agricultural soil and building constructions.

Integrated laser + GPS system

Mara Laser has created and manufactured an integrated system that matches the precision of laser technology with the potential of GPS, perfect for harsh land.
The higher preciseness of the laser signal lays out the plan within a radius of 1300 meters, while the GPS system communicates the location of the leveller. Thus, the Mara system can regulate the height of the tractor leveller and the location of the blade itself.
The creation of the 3D map of the land enables to highlight the land portions that has to be scraped, the loading areas, the section where to begin, and the best way that allows to do the greatest job possible, with both the tractor and the leveller in the right position.
Thus, the operator will have instant instructions through the constant updating of the data by the system.

Fields of application

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

  • Laser levelling machines for agriculture:
    Mara’s laser levellers, among the many benefits secure a key increase of the arable land portions. 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 hours, besides, 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 reduced deflections (max 4 mm) and to annul cavities and gaps that would, afterwords, be filled with concrete. The lowering of work hours and the possibility of obtaining a perfect slope for water to flow down, are other benefits that make these machines incomparable and priceless in this areas.
  • Laser levelling machines for earth-moving:
    the superbe performance of the Mara levellers enables to move large quantity of soil very quickly and with low power. In this way, shorter work hours, lower costs and greater preciseness in creating the horizontal plan and gradient, are achieved.
  • 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 sectors, repairing slope without replacing the lawn.
  • Laser levelling machines for greenhouses:
    thanks to the preciseness, reduced size and easy handling of Mara levellers, it is also feasible to work for the maintenance of green spaces. In this way, the right gradient and also a great aesthetic result are ensured.
  • Laser grader machines for roads:
    in this area, important results are achieved thanks to the capability of the Mara’s laser graders to perform the same job as the motor grader, with minor costs and more convenient times. In addition, there are key benefits, for example specialized labor is no longer necessary, besides to the fact that the use of fine materials is reduced.
