Mara Laser is a business company that for 30 years and more 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 get to important results in many sectors of utility: from agricoltural ground to sport facilities, from building constructions to road excavations, from landscaping to ground scraping.
Mara’s levellers ensure a series of returns and high capacity in more than one situations: from the machine operating velocity, to a total trustworthiness and guarantee of the final success.
Mara’s technology
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 provide an unrivaled performance, mostly when they are combined.
Laser technology
Laser technology is applied to the levellers in a way that without stopping synchronize the height of the blade.
The leveller, 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 inclination of the land and communicates the signal to the receiver, which is instead positioned on the machine itself.
The laser beam, for its own characteristics, enables very high accuracy even over long land portions. After obtaining the signal, a technologically perfectioned rotating pentaprism, positioned on these machines, gives back an ideal pianification for the leveller to follow while operating.
The receiver also plays a very important part, 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 kind of soil and receive the 360° signal, even though it could be poor or it is subjected to interference.
On the leveller, moreover, there is a control system to annul external interference. It decreases wind sound, 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 leveller and the height of the blade.
The levellers, that implement this technology, perceive the laser signal from the satellites: even in this situation the pianification 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 reached up, even though this technology offers less accuracy than laser technology: GPS systems are subject to fluctuations for the periodic change of constellation of the satellites.
In any case, the less accuracy is compensated by the wide elasticity of use, mostly when this technology is used to work on large parts 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 adds the precision of laser technology with the potential of GPS, proper for tough land.
The higher accuracy 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 parts that has to be scraped, the loading areas, the section where to begin, and the best route that enables to do the greatest job possible, with both the tractor and the leveller in the right position.
Hence, the operator will have instant instructions through the constant updating of the data by the system.
Fields of application
The important accuracy and elasticity of the levellers made by Mara Laser assure their use in more than one fields:
- Laser levelling machines for agriculture:
Mara’s laser levellers, among the many plus assure a key increase of the arable parts. They enable a reduction in the amount of water used, they can provide more abundant harvest, 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 gives a 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 times and the possibility of obtaining a perfect slope for water to flow down, are other plus that make these machines incomparable and incomparable 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 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 used very well in this field as it enables to level even existing sectors, repairing slope 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 inclination and also a great aesthetic result are ensured. - Laser grader machines for roads:
in this field, important results are gained thanks to the capacity 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 key plus, for example specialized labor is no longer necessary, besides to the fact that the use of fine materials is reduced.
