Mara Laser is a business company that for over 30 years has been analyzing, producing and trading laser and GPS controlled laser levellers, calling on clients in about 30 states everywhere in the world.
Thanks to GPS and laser control technologies, we can get to considerable results in many sectors of use: from agricoltural ground to sport courts, from building constructions to road excavations, from landscaping to soil scraping.
Mara’s levellers ensure a series of advantages and high productivity in more than one situations: from the machine operating speed regime, to a total affidability 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 system technologies provide 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 leveller, 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 sees the natural gradient of the soil and communicates the signal to the receiver, which is instead put on the machine itself.
The laser beam, for its own characteristics, enables very high accuracy even over long land portions. 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 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, even though it could be low or it is subjected to interference.
On the leveller, also, there is a control system to annul external interference. It cuts wind sound, automatically intercepts the signal and settles the power of the tractor.
GPS system technology
GPS technology, after all, is used to settle the position of the leveller and the height of the blade.
The levellers, that adopt this technology, perceive 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 poorer accuracy than laser technology: GPS systems are subject to fluctuations for 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 land sections with more than one 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 soil.
The higher accuracy of the laser signal shows the plan within a radius of 1300 meters, while the GPS system communicates the location of the leveller. Therefor, the Mara system can settle the height of the tractor leveller and the location of the blade itself.
The creation of the 3D map of the soil enables to highlight the land sections that has to be scraped, the loading areas, the starting point, and the best way that enables to make the best work possible, with both the tractor and the leveller in the right position.
Therefor, the operator will have prompt instructions through the constant updating of the data by the system.
Fields of application
The considerable accuracy and adaptability of the levellers manufactured by Mara Laser secure their use in more than one areas:
- Laser levelling machines for agriculture:
Mara’s laser levellers, among the many conveniences secure a important increase of the arable land sections. They enable a reduction in the amount of water used, an increased production, a less use of chemicals, 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 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 decrease of work times and the possibility of obtaining a perfect slope for water to flow down, are other conveniences that make these machines worthy and incomparable in this areas.
- 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 times, lower costs and greater accuracy in creating the horizontal plan and gradient, are reached.
- 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, contained size and easy handling of Mara laser levellers, it is also doable to work for the maintenance of green spaces. In this way, the right gradient and also a great aesthetic result are secured.
- Laser grader machines for roads:
in this field, important results are reached 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 important conveniences, for example specialized labor is no longer necessary, besides to the fact that the use of fine materials is reduced.
