Mara Laser is a business activity that for 30 years and more has been analyzing, producing and trading laser and GPS controlled laser levellers, turning towards buyers in about 30 nations everywhere in the world.
Thanks to GPS and laser control technologies, we can get to significant results in many areas of use: from agricoltural ground 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 various situations: from the machine running speed regime, to a total affidability and guarantee of the final success.
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 give an unique performance, in particular when they are combined.
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 the elements of the laser control system for levelling.
The transmitter is put on a tripod that sees the natural gradient of the soil and sends the signal to the receiver, which is instead mounted on the machine itself.
The laser beam, for its internal characteristics, permits very high preciseness even over long sections of land. After getting the signal, a technologically perfectioned rotating pentaprism, mounted on these machines, gives back an ideal program for the leveller to follow while running.
The receiver also plays a very important part, 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 low or experiences 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 sets the power of the tractor.
GPS receiver technology
GPS technology, however, 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 program is represented by the signal and reproduced on the soil.
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 for the periodic change of constellation of the satellites.
In any case, the less preciseness is compensated by the wide adaptability of use, in particular when this technology is used to work on large land sections with various inclinations, such as agricoltural ground and building constructions.
Integrated laser + GPS system
Mara Laser has produced and made an integrated system that matches the precision of laser technology with the potential of GPS, suitable for tough soil.
The higher preciseness of the laser signal represents 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 soil permits to highlight the land sections that has to be scraped, the loading areas, the starting point, and the best way that allows to do the greatest job possible, with both the tractor and the leveller in the right position.
Hence, the operator will have instant instructions through the constant updating of the data by the system.
Fields of application
The significant preciseness and adaptability of the levellers made by Mara Laser ensure their use in various fields:
- Laser levelling machines for agriculture:
Mara’s laser levellers, among the many benefits ensure a important increase of the arable land sections. They enable a reduction in the amount of water used, they can provide more abundant harvest, a less use of chemicals, as well as seeds. The decrease in work hours, furthermore, makes the use of these machines a sure investment.
- Laser levelling machines for construction:
Mara Laser provides a perfect precision to obtain ground floors with very contained deflections (max 4 mm) and to annul cavities and gaps that would, later, be filled with concrete. The decrease of work hours and the possibility of obtaining a perfect inclinatoin 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 first-rate 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 gradient, are gained.
- Laser levelling machine for sportsground:
this type of technology can be used very well in this field as it makes possible to level even existing areas, repairing slope without replacing the lawn.
- Laser levelling machines for greenhouses:
thanks to the preciseness, contained size and easy handling of Mara laser levellers, 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 assured.
- Laser grader machines for roads:
in this field, important results are gained thanks to the skills 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 important benefits, for example specialized labor is no longer needed, on top to the fact that the use of fine materials is reduced.
