Mara Laser is a business activity that for over 30 years has been examining, making and marketing laser and GPS controlled laser levelling machines, turning towards clients in about 30 nations all over the world.
Thanks to GPS and laser control technologies, we can get to outstanding results in many sectors of utility: from agricoltural ground to sport facilities, from building constructions to road excavations, from landscaping to soil scraping.
Mara’s levellers ensure a series of advantages and high capacity in various situations: from the machine operating speed regime, to a total affidability and certainty of the result.
Mara’s technology
The technology used by Mara is what makes it unbeatable, and the results obtained all over the world testify this. Laser and GPS receiver technologies provide an unrivaled performance, mostly when they are combined.
Laser technology
Laser technology is applied to the levellers in a way that without stopping synchronize the height of the blade.
The laser levelling machine, 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 tilt of the land and communicates the signal to the receiver, which is instead located on the machine itself.
The laser beam, for its own characteristics, permits very high preciseness even over long sections of land. After getting 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, manufactured by Mara Laser, guarantee the levellers will be able to work on any kind of ground and receive the 360° signal, even though it could be poor or it is subjected to interference.
On the laser levelling machine, moreover, there is a control system to annul external interference. It lowers wind rumble, automatically intercepts the signal and regulates the power of the tractor.
GPS receiver technology
GPS technology, after all, is used to settle the position of the laser levelling machine 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 defined by the signal and reproduced on the land.
Lately, thanks to technological advancement and the use of dedicated software, an accuracy of ± 10 mm has been obtained, even though this technology offers minor accuracy than laser technology: GPS systems are subject to fluctuations for the periodic change of constellation of the satellites.
In any case, the minor preciseness is compensated by the wide adaptability of use, mostly 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 manufactured an integrated system that connects the precision of laser technology with the potential of GPS, suitable for tough land.
The higher preciseness of the laser signal shows the plan within a radius of 1300 meters, while the GPS system communicates the location of the leveller. Therefor, 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 parts that has to be scraped, the loading areas, the section where to begin, and the best route that allows to do the greatest job possible, with both the tractor and the leveller in the right position.
Therefor, the operator will have instant instructions through the constant updating of the data by the system.
Fields of application
The outstanding preciseness and adaptability of the levellers manufactured by Mara Laser secure their use in various fields:
- Laser levelling machines for agriculture:
Mara’s laser levellers, among the many benefits secure a key increase of the arable parts. 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, furthermore, 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 annul cavities and gaps that would, afterwords, be filled with concrete. The lowering of work hours and the possibility of obtaining a perfect slope for water to flow down, are other benefits 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 hours, lower costs and greater preciseness in creating the horizontal plan and tilt, are attained. - 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 preciseness, contained 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 tilt and also a great aesthetic result are assured. - 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 minor 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.
