Mara Laser is a business activity that for 30 years and more has been examining, producing and trading laser and GPS controlled levellers, calling on clients in about 30 states all over the world.
Thanks to GPS and laser control technologies, it is feasible to achieve outstanding results in many areas of use: from agricoltural ground to sport facilities, from building constructions to road excavations, from landscaping to ground scraping.
Mara’s levellers ensure a series of advantages and high productivity in more than one situations: from the machine running velocity, to a total trustworthiness and certainty of the result.
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 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 levelling machine, 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 positioned on the machine itself.
The laser beam, for its own characteristics, enables very high preciseness even over long land portions. After picking up the signal, a technologically perfectioned rotating pentaprism, positioned 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, made by Mara Laser, guarantee the levellers will be able to work on any kind of ground and receive the 360° signal, even if it could be poor or it goes through interference.
On the laser levelling machine, besides, there is a control system to remove external interference. It decreases 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 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 defined 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 obtained, 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, 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 connects the precision of laser technology with the potential of GPS, the right one for harsh land.
The higher preciseness of the laser signal shows 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 allows 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 outstanding preciseness and adaptability 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 conveniences assure a key 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 lowering in work times, besides, 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 reduced deflections (max 4 mm) and to remove cavities and gaps that would, afterwords, be filled with concrete. The lowering of work times 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 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 times, 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 utilized very well in this area as it makes possible to level even existing areas, repairing soil depressions without replacing the lawn.
- Laser levelling machines for greenhouses:
thanks to the preciseness, reduced size and easy handling of Mara levellers, it is also feasible to work for the maintenance of green spaces. In this way, the right gradient and also a fabulous aesthetic result are secured.
- Laser grader machines for roads:
in this area, important results are attained thanks to the skills of the Mara’s laser graders to perform the same job as the motor grader, with minor costs and more convenient times. In addition, there are key conveniences, for example specialized labor is no longer necessary, besides to the fact that the use of fine materials is reduced.
