Mara Laser is a business activity that for over 30 years has been examining, making and marketing laser and GPS controlled levellers, turning towards buyers in about 30 nations all over the world.
Thanks to GPS and laser control technologies, we can reach outstanding results in different sectors of utility: from agricoltural ground to sport courts, from building constructions to road excavations, from landscaping to ground scraping.
Mara’s levellers ensure a series of advantages and high productivity in various situations: from the machine functioning velocity, to a total affidability 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 give an unique performance, mostly when they are combined.
Laser technology is applied to the levellers in a way that without stopping synchronize the height of the blade.
The leveller, the laser beam transmitter and the laser beam receiver are parts of the laser control system for levelling.
The transmitter is positioned on a tripod that examines the natural gradient of the soil and sends the signal to the receiver, which is instead mounted on the machine itself.
The laser beam, beacuse of its own characteristics, enables very high accuracy even over long sections of land. After obtaining the signal, a technologically perfectioned rotating pentaprism, mounted 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, manufactured by Mara Laser, guarantee the levellers will be able to work on any type fo ground and receive the 360° signal, though it could be poor or it is subjected to interference.
On the leveller, also, there is a control system to remove external interference. It lowers 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 leveller and the height of the blade.
The levellers, that implement this technology, get the laser signal from the satellites: even in this situation the program is illustrated 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 obtained, even though this technology offers minor accuracy than laser technology: GPS systems are subject to fluctuations beacuse of the periodic change of constellation of the satellites.
In any case, the minor 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 produced and manufactured an integrated system that adds the precision of laser technology with the potential of GPS, the right one for tough soil.
The higher accuracy of the laser signal lays out the plan within a radius of 1300 meters, while the GPS system communicates the place of the leveller. Thus, 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 soil enables to highlight the land portions that has to be scraped, the loading areas, the starting point, and the best way that allows to make the best work possible, with both the tractor and the leveller in the right position.
Thus, the operator will have instant instructions through the constant updating of the data by the system.
Fields of application
The outstanding accuracy and elasticity of the levellers manufactured by Mara Laser ensure their use in various fields:
- Laser levelling machines for agriculture:
Mara’s laser levellers, among the different benefits ensure a key increase of the arable land portions. They enable 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 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 reduced deflections (max 4 mm) and to remove cavities and gaps that would, afterwords, 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 worthy and incomparable in this fields.
- Laser levelling machines for earth-moving:
the superbe performance of the Mara levellers enables to move large quantity of soil very quickly and with low power. In this way, shorter work hours, 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 enables to level even existing sectors, repairing soil depressions without replacing the lawn.
- Laser levelling machines for greenhouses:
thanks to the accuracy, reduced size and easy handling of Mara levellers, it is also doable to work for the maintenance of green spaces. In this way, the right gradient and also a fabulous aesthetic result are ensured.
- Laser grader machines for roads:
in this field, important results are gained thanks to the capability 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 benefits, for example specialized labor is no longer necessary, on top to the fact that the use of fine materials is reduced.
