Mara Laser is a business activity that for over 30 years has been analyzing, producing and trading laser and GPS controlled levellers, turning towards buyers in about 30 states all over the world.
Thanks to GPS and laser control technologies, we can get to important results in many 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 returns and high capacity in various situations: from the machine running velocity, to a total affidability and certainty of the result.
The technology used by Mara is what makes it unbeatable, and the results obtained all over the world are proof of 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 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 inclination of the land and communicates the signal to the receiver, which is instead mounted 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, mounted on these machines, gives back an ideal program for the leveller to follow while running.
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 move on any kind of ground and receive the 360° signal, even if it could be poor or experiences interference.
On the laser levelling machine, besides, there is a control system to annul external interference. It cuts wind sound, automatically intercepts the signal and sets the power of the tractor.
GPS receiver technology
GPS technology, after all, is used to set the position of the laser levelling machine and the height of the blade.
The levellers, that implement 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.
Nowadays, thanks to technological progress and the use of dedicated software, an accuracy of ± 10 mm has been reached up, 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, 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 created and manufactured an integrated system that adds the precision of laser technology with the potential of GPS, perfect for tough land.
The higher accuracy of the laser signal lays out the plan within a radius of 1300 meters, while the GPS system communicates the precise spot of the leveller. Thus, 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 enables to do the greatest job 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 many conveniences ensure a important increase of the arable parts. 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 reduced 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 inclinatoin for water to flow down, are other conveniences that make these machines worthy and priceless 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 inclination, are gained.
- Laser levelling machine for sportsground:
this type of technology can be utilized very well in this area 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 levellers, it is also doable to work for the maintenance of green spaces. In this way, the right inclination and also a great aesthetic result are ensured.
- Laser grader machines for roads:
in this area, important results are gained thanks to the capacity of the Mara’s laser graders to perform 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.
