Mara Laser is a business company that for over 30 years has been examining, making and marketing laser and GPS controlled levellers, calling on buyers in about 30 states all over the world.
Thanks to GPS and laser control technologies, we can reach significant results in many areas of use: 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 more than one situations: from the machine operating speed regime, to a total trustworthiness and certainty of the result.
The technology used by Mara is what makes it unique, and the results obtained all over the world are proof of this. Laser and GPS system technologies provide an unrivaled performance, in particular when they are combined.
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 located on a tripod that sees the natural gradient of the land and sends the signal to the receiver, which is instead mounted on the machine itself.
The laser beam, as it is one of its internal characteristics, permits very high preciseness even over long sections of land. After picking up the signal, a technologically perfectioned rotating pentaprism, mounted on these machines, gives back an ideal program 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, made by Mara Laser, guarantee the levellers will be able to work on any kind of ground and receive the 360° signal, though it could be low or experiences interference.
On the laser leveller, also, there is a control system to annul external interference. It decreases wind sound, automatically intercepts the signal and regulates the power of the tractor.
GPS system technology
GPS technology, after all, is used to regulate 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 program is illustrated by the signal and reproduced on the land.
Nowadays, thanks to technological progress 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 as it is one of the periodic change of constellation of the satellites.
In any case, the minor 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 agricoltural ground and building constructions.
Integrated laser + GPS system
Mara Laser has produced and made an integrated system that connects the precision of laser technology with the potential of GPS, perfect 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. 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 permits to highlight the parts 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 significant preciseness and adaptability of the levellers made by Mara Laser assure their use in more than one areas:
- Laser levelling machines for agriculture:
Mara’s laser levellers, among the many conveniences assure a key increase of the arable parts. 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 lowering in work times, besides, 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 conveniences 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 times, lower costs and greater preciseness 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 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 assured.
- Laser grader machines for roads:
in this area, important results are achieved thanks to the skills 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 conveniences, for example specialized labor is no longer needed, besides to the fact that the use of fine materials is reduced.
