Leveller blade for construction

Mara Laser is a business company that for 30 years and more has been examining, making and marketing laser and GPS controlled laser levellers, calling on clients in about 30 nations all over the world.
Thanks to GPS and laser control technologies, we can get to important results in many areas of utility: 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 more than one situations: from the machine running speed regime, to a total trustworthiness and certainty 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 continually synchronize the height of the blade.
The 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 sees the natural gradient of the soil and communicates the signal to the receiver, which is instead mounted on the machine itself.
The laser beam, as it is one of its internal characteristics, permits very high preciseness even over long land portions. After picking up 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 has an important role, 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 kind of soil and receive the 360° signal, even though it could be low or it is subjected to interference.
On the leveller, also, there is a control system to annul external interference. It decreases wind sound, automatically captures the signal and settles the power of the tractor.

GPS receiver technology

GPS technology, however, is used to settle the position of the leveller and the height of the blade.
The levellers, that implement this technology, get the laser signal from the satellites: even in this situation the planning is represented by the signal and reproduced on the soil.
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 as it is one of 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 parts with more than one inclinations, such as agricoltural ground and building constructions.

Integrated laser + GPS system

Mara Laser has produced and made an integrated system that matches 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 place of the leveller. Therefor, the Mara system can settle the height of the tractor leveller and the place of the blade itself.
The creation of the 3D map of the soil permits to highlight the parts 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 important preciseness and elasticity of the levellers made by Mara Laser ensure their use in more than one fields:

  • Laser levelling machines for agriculture:
    Mara’s laser levellers, among the many benefits ensure a important increase of the arable parts. They enable a reduction in the amount of water used, an increased production, a considerable reduction of chemicals used, as well as seeds. The lowering in work times, 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, later, be filled with concrete. The lowering of work times and the possibility of obtaining an absolute perfect inclinatoin for water to flow down, are other benefits 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 amount of soil very quickly and with low power. In this way, shorter work times, lower costs and greater preciseness in creating the horizontal plan and gradient, are reached.
  • Laser levelling machine for sportsground:
    this type of technology can be utilized 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 laser levellers, it is also doable to work for the maintenance of green spaces. In this way, the right gradient and also a great aesthetic result are assured.
  • Laser grader machines for roads:
    in this field, important results are reached 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 benefits, for example specialized labor is no longer necessary, besides to the fact that the use of fine materials is reduced.
