Laser leveller blades for construction

Mara Laser is a business company that for over 30 years 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, it is feasible to achieve outstanding results in different sectors of use: from agricultural soil to sportsground, 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 velocity, 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 acquired all over the world witness this. Laser and GPS receiver technologies give an unique performance, mostly 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 put on a tripod that observes the natural inclination of the soil and sends the signal to the receiver, which is instead positioned on the machine itself.
The laser beam, for its internal characteristics, enables very high accuracy even over long sections of land. After picking up 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 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 type fo ground and receive the 360° signal, even if it could be low or it is subjected to interference.
On the leveller, moreover, there is a control system to annul external interference. It decreases wind rumble, automatically intercepts the signal and regulates the power of the tractor.

GPS receiver technology

GPS technology, however, is used to set the position of the leveller and the height of the blade.
The levellers, that adopt this technology, perceive the laser signal from the satellites: even in this situation the pianification 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 less accuracy than laser technology: GPS systems are subject to fluctuations for the periodic change of constellation of the satellites.
In any case, the less accuracy is compensated by the wide elasticity of use, mostly 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, the right one for tough soil.
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 soil enables to highlight the land portions that has to be scraped, the loading areas, the section where to begin, 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 instant instructions through the constant updating of the data by the system.

Fields of application

The outstanding accuracy and elasticity of the levellers manufactured by Mara Laser ensure their use in various fields:

  • Laser levelling machines for agriculture:
    Mara’s laser levellers, among the different benefits ensure a key increase of the arable land portions. They permits a reduction in the amount of water used, an increased production, a less use of chemicals, as well as seeds. The lowering in work times, moreover, 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 reduced deflections (max 4 mm) and to annul cavities and gaps that would, afterwords, be filled with concrete. The lowering of work times and the possibility of obtaining an absolute perfect slope for water to flow down, are other benefits that make these machines worthy and incomparable 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 times, lower costs and greater accuracy in creating the horizontal plan and inclination, 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 sectors, repairing slope without replacing the lawn.
  • Laser levelling machines for greenhouses:
    thanks to the accuracy, reduced 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 inclination and also a fabulous aesthetic result are assured.
  • Laser grader machines for roads:
    in this field, important results are gained 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 necessary, on top to the fact that the use of fine materials is reduced.
