Mara Laser is a business company that for over 30 years has been examining, producing and trading laser and GPS controlled laser levellers, calling on buyers in about 30 nations all over the world.
Thanks to GPS and laser control technologies, it is feasible to achieve considerable results in many sectors of utility: from agricultural soil to sportsground, 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 functioning velocity, to a total affidability and guarantee of the final success.
The technology used by Mara is what makes it unique, and the results acquired all over the world witness this. Laser and GPS system technologies give an unrivaled performance, mostly when they are combined.
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 observes the natural inclination of the land and sends the signal to the receiver, which is instead located on the machine itself.
The laser beam, for its internal characteristics, permits very high accuracy even over long sections of land. After picking up the signal, a technologically perfectioned rotating pentaprism, located on these machines, returns an ideal pianification 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 soil and receive the 360° signal, even if it could be poor or experiences interference.
On the leveller, moreover, there is a control system to remove external interference. It cuts wind rumble, automatically reaches the signal and regulates the power of the tractor.
GPS system technology
GPS technology, after all, is used to settle the position of the 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 pianification is represented by the signal and reproduced on the land.
Nowadays, 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 adaptability of use, mostly when this technology is used to work on large land portions with more than one inclinations, such as agricultural soil and building constructions.
Integrated laser + GPS system
Mara Laser has created and made an integrated system that connects the precision of laser technology with the potential of GPS, the right one for tough land.
The higher accuracy of the laser signal shows the plan within a radius of 1300 meters, while the GPS system communicates the location of the leveller. Hence, the Mara system can settle the height of the tractor leveller and the location of the blade itself.
The creation of the 3D map of the land permits to highlight the land portions that has to be scraped, the loading areas, the point where to start, and the best route that allows to make the best work possible, with both the tractor and the leveller in the right position.
Hence, the operator will have prompt instructions through the constant updating of the data by the system.
Fields of application
The considerable accuracy and adaptability of the levellers made by Mara Laser secure their use in more than one fields:
- Laser levelling machines for agriculture:
Mara’s laser levellers, among the many plus secure a key increase of the arable land portions. They permits a reduction in the amount of water used, they can provide more abundant harvest, a considerable reduction of chemicals used, as well as seeds. The decrease in work times, moreover, makes the use of these machines a sure investment.
- Laser levelling machines for construction:
Mara Laser gives a perfect precision to obtain ground floors with very contained deflections (max 4 mm) and to remove cavities and gaps that would, later, be filled with concrete. The decrease of work times and the possibility of obtaining a perfect inclinatoin for water to flow down, are other plus that make these machines incomparable and incomparable in this fields.
- Laser levelling machines for earth-moving:
the fine 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 accuracy in creating the horizontal plan and inclination, are achieved.
- 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 doable to work for the maintenance of green spaces. In this way, the right inclination and also a fabulous aesthetic result are secured.
- Laser grader machines for roads:
in this area, important results are achieved thanks to the capability 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 needed, on top to the fact that the use of fine materials is reduced.
