Mara Laser is a business company that for over 30 years has been examining, making and trading laser and GPS controlled laser levelling machines, turning towards buyers in about 30 nations all over the world.
Thanks to GPS and laser control technologies, we can reach outstanding results in many sectors of use: from agricultural soil to sport facilities, from building constructions to road excavations, from landscaping to soil scraping.
Mara’s levellers ensure a series of returns and high capacity in more than one situations: from the machine functioning velocity, to a total affidability and assurance of the result.
The technology used by Mara is what makes it unique, and the results obtained all over the world testify this. Laser and GPS receiver technologies provide an unrivaled performance, mostly when they are used together.
Laser technology is applied to the levellers in a way that continually synchronize the height of the blade.
The laser levelling machine, the laser beam transmitter and the laser beam receiver are parts of the laser control system for levelling.
The transmitter is positioned on a tripod that observes the natural gradient of the land and sends the signal to the receiver, which is instead put on the machine itself.
The laser beam, for its own characteristics, enables very high preciseness even over long sections of land. After picking up 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, made by Mara Laser, guarantee the levellers will be able to work on any kind of soil and receive the 360° signal, even though it could be low or experiences interference.
On the laser levelling machine, also, there is a control system to remove external interference. It lowers wind rumble, automatically reaches the signal and regulates the power of the tractor.
GPS receiver technology
GPS technology, however, is used to regulate the position of the laser levelling machine 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 illustrated by the signal and reproduced on the land.
Lately, 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 for the periodic change of constellation of the satellites.
In any case, the less preciseness is compensated by the wide adaptability of use, mostly when this technology is used to work on large land sections with more than one inclinations, such as agricultural soil and building constructions.
Integrated laser + GPS system
Mara Laser has produced and made an integrated system that adds the precision of laser technology with the potential of GPS, proper for harsh land.
The higher preciseness 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 regulate the height of the tractor leveller and the place 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 point where to start, and the best route that enables to make the best work possible, with both the tractor and the leveller in the right position.
Therefor, the operator will have immediate instructions through the constant updating of the data by the system.
Fields of application
The outstanding preciseness and adaptability of the levellers made by Mara Laser ensure their use in more than one areas:
- Laser levelling machines for agriculture:
Mara’s laser levellers, among the many conveniences 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 an absolute perfect precision to obtain ground floors with very reduced deflections (max 4 mm) and to remove cavities and gaps that would, afterwords, 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 conveniences that make these machines priceless and incomparable 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 preciseness in creating the horizontal plan and gradient, are attained.
- Laser levelling machine for sportsground:
this type of technology can be utilized very well in this field as it makes possible to level even existing sectors, repairing slope without replacing the lawn.
- Laser levelling machines for greenhouses:
thanks to the preciseness, reduced size and easy handling of Mara laser levelling machines, it is also feasible to work for the maintenance of green spaces. In this way, the right gradient and also a great aesthetic result are secured.
- Laser grader machines for roads:
in this field, important results are attained thanks to the capacity 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 conveniences, for example specialized labor is no longer necessary, besides to the fact that the use of fine materials is reduced.
