Laser leveller blades for sportsfields

Mara Laser is a business company that for 30 years and more has been analyzing, making and trading laser and GPS controlled laser levellers, calling on clients in about 30 states all over the world.
Thanks to GPS and laser control technologies, it is feasible to achieve outstanding results in different sectors of use: from agricoltural ground to sport facilities, 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 operating speed regime, to a total trustworthiness 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 are proof of this. Laser and GPS system technologies provide 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 located on a tripod that sees the natural tilt of the soil and sends the signal to the receiver, which is instead located on the machine itself.
The laser beam, as it is one of its own characteristics, enables very high accuracy even over long land portions. After obtaining the signal, a technologically perfectioned rotating pentaprism, located on these machines, gives back an ideal pianification for the leveller to follow while operating.
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 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 decreases wind sound, automatically intercepts the signal and regulates the power of the tractor.

GPS system 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, get the laser signal from the satellites: even in this situation the pianification is represented by the signal and reproduced on the soil.
Nowadays, thanks to technological advancement and the use of dedicated software, an accuracy of ± 10 mm has been reached up, even though this technology offers poorer 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 poorer accuracy is compensated by the wide elasticity of use, in particular when this technology is used to work on large parts 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, the right one for tough soil.
The higher accuracy of the laser signal represents the plan within a radius of 1300 meters, while the GPS system communicates the location of the leveller. Thus, the Mara system can set the height of the tractor leveller and the location of the blade itself.
The creation of the 3D map of the soil enables to highlight the parts that has to be scraped, the loading areas, the point where to start, and the best route that enables 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 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 different 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 hours, moreover, 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 contained 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 inclinatoin for water to flow down, are other benefits that make these machines incomparable and incomparable 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 accuracy in creating the horizontal plan and tilt, are reached.
  • Laser levelling machine for sportsground:
    this type of technology can be used very well in this area as it enables to level even existing sectors, repairing soil depressions without replacing the lawn.
  • Laser levelling machines for greenhouses:
    thanks to the accuracy, contained size and easy handling of Mara laser levellers, it is also feasible to work for the maintenance of green spaces. In this way, the right tilt and also a great aesthetic result are ensured.
  • Laser grader machines for roads:
    in this area, important results are reached thanks to the skills of the Mara’s laser graders to provide the same job as the motor grader, with poorer 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.
