Mara Laser is a business activity that for 30 years and more has been analyzing, 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, it is feasible to achieve considerable results in many sectors 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 functioning velocity, to a total trustworthiness and assurance of the result.
The technology used by Mara is what makes it unique, and the results acquired all over the world witness this. Laser and GPS receiver technologies give an unrivaled performance, in particular 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 the elements of the laser control system for levelling.
The transmitter is positioned on a tripod that observes the natural gradient of the land and sends the signal to the receiver, which is instead mounted on the machine itself.
The laser beam, for its internal characteristics, enables very high preciseness even over long land portions. After getting 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 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 move on any kind of soil and receive the 360° signal, though it could be low or it goes through interference.
On the laser levelling machine, moreover, there is a control system to remove external interference. It decreases wind sound, automatically captures the signal and settles the power of the tractor.
GPS receiver technology
GPS technology, after all, is used to settle the position of the laser levelling machine and the height of the blade.
The levellers, that adopt this technology, get the laser signal from the satellites: even in this situation the program is illustrated 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 reached up, 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 adaptability of use, in particular when this technology is used to work on large land sections with various inclinations, such as agricoltural ground and building constructions.
Integrated laser + GPS system
Mara Laser has created and manufactured an integrated system that matches the precision of laser technology with the potential of GPS, the right one for tough land.
The higher preciseness of the laser signal represents the plan within a radius of 1300 meters, while the GPS system communicates the place of the leveller. Hence, the Mara system can settle the height of the tractor leveller and the place of the blade itself.
The creation of the 3D map of the land enables to highlight the land sections that has to be scraped, the loading areas, the starting point, and the best way that enables to do the greatest job possible, with both the tractor and the leveller in the right position.
Hence, the operator will have prompt instructions through the constant updating of the data by the system.
Fields of application
The considerable preciseness and adaptability of the levellers manufactured by Mara Laser ensure their use in various fields:
- Laser levelling machines for agriculture:
Mara’s laser levellers, among the many conveniences ensure a important increase of the arable land sections. 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 hours, furthermore, 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 hours and the possibility of obtaining an absolute perfect inclinatoin for water to flow down, are other conveniences that make these machines priceless and incomparable in this fields.
- Laser levelling machines for earth-moving:
the fine 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 preciseness 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 area 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 doable 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 area, important results are attained 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 important conveniences, for example specialized labor is no longer necessary, on top to the fact that the use of fine materials is reduced.
