Mara Laser is a business activity that for 30 years and more has been examining, making and marketing laser and GPS controlled levellers, turning towards clients in about 30 nations all over the world.
Thanks to GPS and laser control technologies, we can get to significant results in different areas of use: from agricultural soil 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 various situations: from the machine functioning speed regime, to a total affidability and assurance of the result.
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 receiver technologies give an unrivaled performance, mostly when they are used together.
Laser technology is applied to the levellers in a way that without stopping synchronize the height of the blade.
The laser 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 inclination of the land and sends the signal to the receiver, which is instead put on the machine itself.
The laser beam, beacuse of its own characteristics, enables 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 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, manufactured 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 laser leveller, moreover, there is a control system to annul external interference. It cuts wind sound, automatically captures the signal and regulates the power of the tractor.
GPS receiver technology
GPS technology, however, is used to settle the position of the laser 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 defined by the signal and reproduced on the land.
Nowadays, thanks to technological progress and the use of dedicated software, an accuracy of ± 10 mm has been reached up, even though this technology offers less accuracy than laser technology: GPS systems are subject to fluctuations beacuse of 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 sections with various inclinations, such as agricultural soil and building constructions.
Integrated laser + GPS system
Mara Laser has created and manufactured an integrated system that adds the precision of laser technology with the potential of GPS, the right one for tough land.
The higher accuracy of the laser signal lays out the plan within a radius of 1300 meters, while the GPS system communicates the precise spot of the leveller. Thus, the Mara system can settle the height of the tractor leveller and the precise spot of the blade itself.
The creation of the 3D map of the land enables to highlight the land sections that has to be scraped, the loading areas, the section where to begin, and the best route that allows to make the best work possible, with both the tractor and the leveller in the right position.
Thus, the operator will have immediate instructions through the constant updating of the data by the system.
Fields of application
The significant accuracy and elasticity of the levellers manufactured by Mara Laser ensure their use in various areas:
- Laser levelling machines for agriculture:
Mara’s laser levellers, among the different benefits ensure a key increase of the arable land sections. They permits 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, furthermore, 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 annul cavities and gaps that would, later, be filled with concrete. The lowering of work hours and the possibility of obtaining an absolute perfect slope for water to flow down, are other benefits that make these machines incomparable and priceless in this areas.
- Laser levelling machines for earth-moving:
the first-rate performance of the Mara levellers enables to move large amount 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 inclination, are attained.
- Laser levelling machine for sportsground:
this type of technology can be used very well in this area as it enables to level even existing areas, repairing soil depressions without replacing the lawn.
- Laser levelling machines for greenhouses:
thanks to the accuracy, reduced size and easy handling of Mara levellers, it is also feasible to work for the maintenance of green spaces. In this way, the right inclination and also a fabulous aesthetic result are ensured.
- Laser grader machines for roads:
in this area, important results are attained thanks to the capacity of the Mara’s laser graders to provide 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 needed, besides to the fact that the use of fine materials is reduced.
