Mara Laser is a business company that for 30 years and more has been examining, producing and marketing laser and GPS controlled levellers, calling on buyers in about 30 nations all over the world.
Thanks to GPS and laser control technologies, we can reach important results in many sectors of use: from agricoltural ground to sportsground, from building constructions to road excavations, from landscaping to soil scraping.
Mara’s levellers ensure a series of returns and high productivity in more than one situations: from the machine operating speed regime, to a total affidability and assurance of the result.
The technology used by Mara is what makes it unbeatable, and the results obtained all over the world testify this. Laser and GPS system technologies provide 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 leveller, 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 sees the natural gradient of the land and communicates the signal to the receiver, which is instead put on the machine itself.
The laser beam, for its internal characteristics, permits very high preciseness even over long sections of land. After picking up the signal, a technologically perfectioned rotating pentaprism, put on these machines, returns an ideal pianification 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 move on any kind of ground and receive the 360° signal, even if it could be low or experiences interference.
On the laser leveller, also, there is a control system to annul external interference. It decreases wind rumble, automatically captures the signal and regulates the power of the tractor.
GPS system technology
GPS technology, however, is used to settle the position of the laser leveller and the height of the blade.
The levellers, that implement this technology, obtain the laser signal from the satellites: even in this situation the pianification is represented 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 for the periodic change of constellation of the satellites.
In any case, the minor preciseness is compensated by the wide elasticity of use, in particular when this technology is used to work on large land portions 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 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 precise spot of the leveller. Therefor, the Mara system can settle the height of the tractor leveller and the precise spot of the blade itself.
The creation of the 3D map of the land permits to highlight the land portions that has to be scraped, the loading areas, the point where to start, and the best way that allows to do the greatest job 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 important preciseness and elasticity of the levellers made 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 land portions. They enable 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, 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 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 a perfect slope for water to flow down, are other plus that make these machines incomparable 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 gained.
- Laser levelling machine for sportsground:
this type of technology can be used very well in this field as it enables to level even existing sectors, repairing soil depressions 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 ensured.
- Laser grader machines for roads:
in this field, important results are gained thanks to the capacity 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 plus, for example specialized labor is no longer needed, on top to the fact that the use of fine materials is reduced.
