Mara Laser is a business activity that for 30 years and more has been examining, producing and marketing laser and GPS controlled levellers, calling on buyers in about 30 nations everywhere in the world.
Thanks to GPS and laser control technologies, we can reach outstanding results in different areas of utility: 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 trustworthiness 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 are proof of this. Laser and GPS receiver technologies give an unrivaled performance, mostly when they are used together.
Laser technology
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 put on a tripod that examines the natural gradient of the land and communicates the signal to the receiver, which is instead put on the machine itself.
The laser beam, as it is one of its own characteristics, permits very high accuracy even over long sections of land. After getting the signal, a technologically perfectioned rotating pentaprism, put on these machines, returns an ideal pianification for the leveller to follow while functioning.
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 type fo ground 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 rumble, automatically captures the signal and settles the power of the tractor.
GPS receiver technology
GPS technology, however, is used to set 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 represented 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 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, 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, proper for tough land.
The higher accuracy of the laser signal represents the plan within a radius of 1300 meters, while the GPS system communicates the place of the leveller. Therefor, the Mara system can set the height of the tractor leveller and the place of the blade itself.
The creation of the 3D map of the land permits to highlight the land sections that has to be scraped, the loading areas, the point where to start, 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 prompt instructions through the constant updating of the data by the system.
Fields of application
The outstanding 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 plus ensure a key increase of the arable land sections. 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 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 reduced 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 plus that make these machines worthy and priceless in this areas. - Laser levelling machines for earth-moving:
the fine 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 achieved. - Laser levelling machine for sportsground:
this type of technology can be utilized very well in this area as it makes possible 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 doable to work for the maintenance of green spaces. In this way, the right gradient and also a fabulous aesthetic result are ensured. - Laser grader machines for roads:
in this area, important results are achieved 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 plus, for example specialized labor is no longer needed, on top to the fact that the use of fine materials is reduced.
