Mara Laser is a business company that for over 30 years has been analyzing, making and marketing 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, it is feasible to achieve important results in different sectors of use: from agricoltural ground to sportsground, from building constructions to road excavations, from landscaping to ground scraping.
Mara’s levellers ensure a series of advantages and high capacity in more than one situations: from the machine operating velocity, to a total trustworthiness and guarantee of the final success.
The technology used by Mara is what makes it unique, and the results acquired all over the world witness 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 laser levelling machine, 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 land and communicates the signal to the receiver, which is instead positioned on the machine itself.
The laser beam, beacuse of its own characteristics, enables very high accuracy even over long sections of land. After picking up the signal, a technologically perfectioned rotating pentaprism, positioned on these machines, returns an ideal program for the leveller to follow while operating.
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 work on any type fo ground and receive the 360° signal, even though 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 decreases wind sound, automatically captures 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 land.
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 adaptability of use, mostly 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 created and made an integrated system that connects 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 location of the leveller. Therefor, the Mara system can regulate the height of the tractor leveller and the location of the blade itself.
The creation of the 3D map of the land enables to highlight the land portions that has to be scraped, the loading areas, the section where to begin, and the best route that allows to do the greatest job possible, with both the tractor and the leveller in the right position.
Therefor, the operator will have instant instructions through the constant updating of the data by the system.
Fields of application
The important accuracy and adaptability of the levellers made by Mara Laser secure their use in more than one fields:
- Laser levelling machines for agriculture:
Mara’s laser levellers, among the different plus secure 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 less use of chemicals, as well as seeds. The lowering in work hours, moreover, 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, later, be filled with concrete. The lowering of work hours and the possibility of obtaining a perfect slope for water to flow down, are other plus that make these machines priceless and priceless in this fields.
- Laser levelling machines for earth-moving:
the superbe performance of the Mara levellers enables to move large amount 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 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 sectors, repairing slope 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 fabulous aesthetic result are assured.
- Laser grader machines for roads:
in this field, important results are attained 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 plus, for example specialized labor is no longer needed, besides to the fact that the use of fine materials is reduced.
