Laser leveller blade for sportsfields

Mara Laser is a business company that for 30 years and more has been examining, making and trading laser and GPS controlled laser levelling machines, calling on buyers in about 30 states everywhere in the world.
Thanks to GPS and laser control technologies, it is feasible to achieve considerable results in many sectors of use: 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 functioning speed regime, to a total trustworthiness and guarantee of the final success.

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 receiver technologies give an unrivaled 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 the elements of the laser control system for levelling.
The transmitter is placed on a tripod that observes the natural gradient of the soil and sends the signal to the receiver, which is instead put 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 obtaining the signal, a technologically perfectioned rotating pentaprism, put on these machines, gives back an ideal planning for the leveller to follow while functioning.
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 ground and receive the 360° signal, though it could be low or it is subjected to interference.
On the leveller, besides, there is a control system to remove external interference. It lowers wind sound, automatically intercepts the signal and regulates 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 adopt this technology, perceive 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 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 elasticity of use, in particular when this technology is used to work on large land portions with various inclinations, such as agricoltural ground and building constructions.

Integrated laser + GPS system

Mara Laser has created and made an integrated system that matches the precision of laser technology with the potential of GPS, suitable for tough soil.
The higher accuracy of the laser signal shows 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 land portions that has to be scraped, the loading areas, the section where to begin, 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 considerable accuracy and elasticity of the levellers made by Mara Laser ensure their use in various areas:

  • Laser levelling machines for agriculture:
    Mara’s laser levellers, among the many plus ensure a key increase of the arable land portions. They enable a reduction in the amount of water used, an increased production, 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 gives an absolute perfect precision to obtain ground floors with very reduced deflections (max 4 mm) and to remove cavities and gaps that would, later, be filled with concrete. The lowering of work hours and the possibility of obtaining an absolute perfect inclinatoin for water to flow down, are other plus that make these machines priceless and priceless in this areas.
  • Laser levelling machines for earth-moving:
    the superbe performance of the Mara levellers permits to move large quantity of soil very quickly and with low power. In this way, shorter work hours, lower costs and greater accuracy in creating the horizontal plan and gradient, are reached.
  • Laser levelling machine for sportsground:
    this type of technology can be used 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 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 gradient and also a great aesthetic result are ensured.
  • Laser grader machines for roads:
    in this area, important results are reached 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 plus, for example specialized labor is no longer necessary, besides to the fact that the use of fine materials is reduced.
