Mara Laser is a business activity that for over 30 years has been analyzing, producing and trading laser and GPS controlled laser levellers, calling on buyers in about 30 states everywhere in the world.
Thanks to GPS and laser control technologies, we can reach important results in different areas of utility: from agricoltural ground to sportsground, from building constructions to road excavations, from landscaping to ground scraping.
Mara’s levellers ensure a series of returns and high capacity in various 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 receiver technologies provide an unique performance, mostly when they are used together.
Laser technology is applied to the levellers in a way that without stopping synchronize the height of the blade.
The laser leveller, the laser beam transmitter and the laser beam receiver are parts of the laser control system for levelling.
The transmitter is put on a tripod that observes the natural gradient of the land and communicates 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 land portions. After obtaining 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, though it could be low or it is subjected to interference.
On the laser leveller, also, there is a control system to annul external interference. It lowers wind rumble, automatically intercepts the signal and regulates the power of the tractor.
GPS receiver technology
GPS technology, after all, is used to settle the position of the laser leveller 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 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 obtained, even though this technology offers less accuracy than laser technology: GPS systems are subject to fluctuations beacuse of the periodic change of constellation of the satellites.
In any case, the less accuracy is compensated by the wide adaptability of use, mostly 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 adds the precision of laser technology with the potential of GPS, perfect for harsh land.
The higher accuracy of the laser signal shows the plan within a radius of 1300 meters, while the GPS system communicates the precise spot of the leveller. Thus, the Mara system can settle 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 land sections that has to be scraped, the loading areas, the section where to begin, and the best way that enables 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 important accuracy and adaptability of the levellers manufactured by Mara Laser ensure their use in various areas:
- Laser levelling machines for agriculture:
Mara’s laser levellers, among the different conveniences ensure a important increase of the arable land sections. They enable a reduction in the amount of water used, an increased production, 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 gives an absolute perfect precision to obtain ground floors with very reduced deflections (max 4 mm) and to annul cavities and gaps that would, afterwords, 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 priceless in this areas.
- 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 gained.
- Laser levelling machine for sportsground:
this type of technology can be utilized very well in this field as it enables to level even existing areas, repairing soil depressions without replacing the lawn.
- Laser levelling machines for greenhouses:
thanks to the accuracy, reduced 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 fabulous aesthetic result are assured.
- Laser grader machines for roads:
in this field, important results are gained thanks to the skills of the Mara’s laser graders to provide the same job as the motor grader, with less costs and more convenient times. In addition, there are important conveniences, for example specialized labor is no longer needed, on top to the fact that the use of fine materials is reduced.
