Mara Laser is a business activity that for 30 years and more has been examining, making and trading laser and GPS controlled levellers, calling on buyers in about 30 states everywhere in the world.
Thanks to GPS and laser control technologies, we can reach significant results in different areas of use: 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 operating 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 obtained all over the world testify this. Laser and GPS receiver technologies give an unrivaled performance, in particular 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 parts of the laser control system for levelling.
The transmitter is placed on a tripod that examines the natural tilt of the land and sends the signal to the receiver, which is instead put on the machine itself.
The laser beam, beacuse of its internal characteristics, enables very high accuracy even over long sections of land. After picking up the signal, a technologically perfectioned rotating pentaprism, put on these machines, returns 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, manufactured by Mara Laser, guarantee the levellers will be able to work on any type fo ground and receive the 360° signal, even if it could be low or it is subjected to interference.
On the laser levelling machine, besides, there is a control system to annul external interference. It cuts wind rumble, automatically reaches the signal and regulates the power of the tractor.
GPS receiver technology
GPS technology, however, is used to set the position of the laser levelling machine 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 defined by the signal and reproduced on the land.
Lately, 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 beacuse of the periodic change of constellation of the satellites.
In any case, the poorer accuracy is compensated by the wide adaptability of use, in particular when this technology is used to work on large parts with various inclinations, such as agricoltural ground and building constructions.
Integrated laser + GPS system
Mara Laser has produced and manufactured an integrated system that matches the precision of laser technology with the potential of GPS, perfect for harsh land.
The higher accuracy of the laser signal represents the plan within a radius of 1300 meters, while the GPS system communicates the precise spot of the leveller. Hence, the Mara system can set the height of the tractor leveller and the precise spot of the blade itself.
The creation of the 3D map of the land enables to highlight the parts 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 immediate instructions through the constant updating of the data by the system.
Fields of application
The significant accuracy and adaptability of the levellers manufactured 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 parts. They permits a reduction in the amount of water used, they can provide more abundant harvest, a less use of chemicals, as well as seeds. The decrease in work times, besides, 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 contained deflections (max 4 mm) and to annul cavities and gaps that would, afterwords, be filled with concrete. The decrease of work times and the possibility of obtaining a perfect slope for water to flow down, are other plus that make these machines priceless and incomparable in this areas.
- 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 times, lower costs and greater accuracy in creating the horizontal plan and tilt, are attained.
- 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 levellers, it is also doable to work for the maintenance of green spaces. In this way, the right tilt and also a great aesthetic result are secured.
- Laser grader machines for roads:
in this field, important results are attained thanks to the capacity of the Mara’s laser graders to perform 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.
