Mara - Laser Levelers

Catalogue

Used leveller blade for greenhouses and landscaping

Mara Laser is a business company that for 30 years and more has been examining, producing and trading laser and GPS controlled levellers, calling on buyers in about 30 states all over the world.
Thanks to GPS and laser control technologies, we can reach considerable results in different areas of utility: from agricoltural ground to sport facilities, from building constructions to road excavations, from landscaping to soil 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 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 receiver technologies provide 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 leveller, the laser beam transmitter and the laser beam receiver are the elements of the laser control system for levelling.
The transmitter is located on a tripod that examines the natural tilt of the soil and sends the signal to the receiver, which is instead mounted on the machine itself.
The laser beam, as it is one of its own characteristics, enables very high preciseness even over long land portions. After getting the signal, a technologically perfectioned rotating pentaprism, mounted on these machines, gives back an ideal planning for the leveller to follow while running.
The receiver also plays a very important part, 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 though it could be poor or it is subjected to interference.
On the laser leveller, moreover, there is a control system to annul external interference. It cuts wind rumble, automatically reaches the signal and sets the power of the tractor.

GPS receiver 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, perceive the laser signal from the satellites: even in this situation the planning is defined by the signal and reproduced on the soil.
Nowadays, thanks to technological progress 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 as it is one of the periodic change of constellation of the satellites.
In any case, the less preciseness is compensated by the wide elasticity of use, in particular when this technology is used to work on large land sections with various inclinations, such as agricoltural ground and building constructions.

Integrated laser + GPS system

Mara Laser has created and made an integrated system that adds the precision of laser technology with the potential of GPS, proper for tough soil.
The higher preciseness 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. Thus, 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 sections that has to be scraped, the loading areas, the section where to begin, and the best route that allows to do the greatest job 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 considerable preciseness and elasticity of the levellers made by Mara Laser ensure their use in various fields:

  • Laser levelling machines for agriculture:
    Mara’s laser levellers, among the different plus ensure 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 decrease in work hours, furthermore, 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, afterwords, be filled with concrete. The decrease of work hours and the possibility of obtaining an absolute perfect inclinatoin for water to flow down, are other plus that make these machines incomparable and priceless in this fields.
  • 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 tilt, are gained.
  • 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 preciseness, 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 great aesthetic result are secured.
  • Laser grader machines for roads:
    in this field, important results are gained thanks to the skills 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 plus, for example specialized labor is no longer necessary, besides to the fact that the use of fine materials is reduced.
