Mara Laser is a business activity that for over 30 years has been analyzing, producing and trading laser and GPS controlled laser levelling machines, calling on buyers in about 30 states everywhere in the world.
Thanks to GPS and laser control technologies, we can get to considerable results in different areas of utility: from agricoltural ground to sport facilities, from building constructions to road excavations, from landscaping to ground scraping.
Mara’s levellers ensure a series of returns and high capacity in various situations: from the machine functioning velocity, to a total trustworthiness 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 system 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 the elements of the laser control system for levelling.
The transmitter is placed on a tripod that sees the natural gradient of the soil and sends the signal to the receiver, which is instead positioned on the machine itself.
The laser beam, as it is one of its internal characteristics, enables very high accuracy even over long sections of land. After obtaining the signal, a technologically perfectioned rotating pentaprism, positioned on these machines, returns an ideal program 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 move on any type fo ground and receive the 360° signal, even if it could be poor or experiences interference.
On the laser levelling machine, moreover, there is a control system to remove external interference. It lowers wind rumble, automatically intercepts the signal and sets the power of the tractor.
GPS system technology
GPS technology, after all, is used to regulate the position of the laser levelling machine and the height of the blade.
The levellers, that adopt this technology, obtain the laser signal from the satellites: even in this situation the program is represented by the signal and reproduced on the soil.
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 as it is one of the periodic change of constellation of the satellites.
In any case, the less accuracy is compensated by the wide elasticity of use, mostly when this technology is used to work on large land portions with various inclinations, such as agricoltural ground and building constructions.
Integrated laser + GPS system
Mara Laser has created and made an integrated system that connects the precision of laser technology with the potential of GPS, suitable for tough soil.
The higher accuracy of the laser signal shows the plan within a radius of 1300 meters, while the GPS system communicates the precise spot of the leveller. Hence, the Mara system can regulate the height of the tractor leveller and the precise spot of the blade itself.
The creation of the 3D map of the soil enables to highlight the land portions that has to be scraped, the loading areas, the section where to begin, 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 considerable accuracy and elasticity of the levellers made by Mara Laser assure their use in various areas:
- Laser levelling machines for agriculture:
Mara’s laser levellers, among the different plus assure a key increase of the arable land portions. 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 decrease 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 remove cavities and gaps that would, later, be filled with concrete. The decrease of work times and the possibility of obtaining an absolute perfect slope for water to flow down, are other plus that make these machines incomparable 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 times, lower costs and greater accuracy 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 soil depressions without replacing the lawn.
- Laser levelling machines for greenhouses:
thanks to the accuracy, contained 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 assured.
- 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 less costs and more convenient times. In addition, there are key plus, for example specialized labor is no longer necessary, besides to the fact that the use of fine materials is reduced.
