Mara Laser is a business company that for 30 years and more has been analyzing, making and trading laser and GPS controlled levellers, calling on clients in about 30 nations everywhere in the world.
Thanks to GPS and laser control technologies, we can reach considerable results in many sectors of utility: from agricultural soil 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 more than one situations: from the machine running speed regime, to a total trustworthiness and guarantee of the final success.
The technology used by Mara is what makes it unbeatable, and the results acquired all over the world witness this. Laser and GPS system 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 parts of the laser control system for levelling.
The transmitter is located on a tripod that observes the natural gradient of the land and sends the signal to the receiver, which is instead located 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, located on these machines, returns an ideal planning 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, 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 low or experiences interference.
On the laser levelling machine, also, there is a control system to annul external interference. It decreases wind rumble, automatically intercepts the signal and settles the power of the tractor.
GPS system technology
GPS technology, after all, is used to set 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 planning is defined by the signal and reproduced on the land.
Nowadays, thanks to technological advancement and the use of dedicated software, an accuracy of ± 10 mm has been reached up, even though this technology offers poorer accuracy than laser technology: GPS systems are subject to fluctuations for the periodic change of constellation of the satellites.
In any case, the poorer preciseness is compensated by the wide adaptability of use, in particular when this technology is used to work on large parts with more than one inclinations, such as agricultural soil and building constructions.
Integrated laser + GPS system
Mara Laser has created and manufactured an integrated system that matches the precision of laser technology with the potential of GPS, proper for tough land.
The higher preciseness of the laser signal lays out the plan within a radius of 1300 meters, while the GPS system communicates the place of the leveller. Hence, 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 parts 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 immediate instructions through the constant updating of the data by the system.
Fields of application
The considerable preciseness and adaptability of the levellers manufactured by Mara Laser secure their use in more than one areas:
- Laser levelling machines for agriculture:
Mara’s laser levellers, among the many plus secure a key increase of the arable parts. 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 times, moreover, makes the use of these machines a sure investment.
- Laser levelling machines for construction:
Mara Laser provides an absolute 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 times and the possibility of obtaining an absolute perfect slope for water to flow down, are other plus that make these machines priceless and priceless in this areas.
- Laser levelling machines for earth-moving:
the first-rate performance of the Mara levellers permits to move large quantity of soil very quickly and with low power. In this way, shorter work times, lower costs and greater preciseness in creating the horizontal plan and gradient, are reached.
- Laser levelling machine for sportsground:
this type of technology can be used very well in this area as it enables 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 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 secured.
- Laser grader machines for roads:
in this area, important results are reached thanks to the skills of the Mara’s laser graders to provide the same job as the motor grader, with poorer costs and more convenient times. In addition, there are key plus, for example specialized labor is no longer necessary, on top to the fact that the use of fine materials is reduced.
