Mara Laser is a business activity that for 30 years and more has been analyzing, making and marketing laser and GPS controlled laser levellers, calling on clients in about 30 nations all over the world.
Thanks to GPS and laser control technologies, we can reach significant results in different areas of utility: from agricoltural ground to sport facilities, from building constructions to road excavations, from landscaping to soil scraping.
Mara’s levellers ensure a series of advantages and high capacity in various situations: from the machine operating velocity, to a total affidability and guarantee of the final success.
Mara’s technology
The technology used by Mara is what makes it unique, and the results obtained all over the world testify this. Laser and GPS receiver technologies give an unrivaled performance, in particular when they are used together.
Laser technology
Laser technology is applied to the levellers in a way that continually 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 located on a tripod that examines the natural tilt of the soil and sends the signal to the receiver, which is instead positioned on the machine itself.
The laser beam, beacuse of its own characteristics, permits very high preciseness even over long land portions. After obtaining the signal, a technologically perfectioned rotating pentaprism, positioned on these machines, gives back an ideal planning 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, made by Mara Laser, guarantee the levellers will be able to move on any kind of ground and receive the 360° signal, though it could be low or experiences interference.
On the laser leveller, moreover, there is a control system to remove external interference. It lowers wind sound, automatically intercepts the signal and sets the power of the tractor.
GPS receiver technology
GPS technology, however, is used to set the position of the laser leveller and the height of the blade.
The levellers, that implement this technology, get the laser signal from the satellites: even in this situation the planning is defined by the signal and reproduced on the soil.
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 preciseness is compensated by the wide elasticity 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 made an integrated system that matches the precision of laser technology with the potential of GPS, the right one for harsh soil.
The higher preciseness 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 set the height of the tractor leveller and the location of the blade itself.
The creation of the 3D map of the soil permits to highlight the parts that has to be scraped, the loading areas, the point where to start, and the best way that enables to do the greatest job 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 significant preciseness and elasticity of the levellers made by Mara Laser secure their use in various fields:
- Laser levelling machines for agriculture:
Mara’s laser levellers, among the different benefits secure 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 gives a 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 decrease of work times and the possibility of obtaining a perfect inclinatoin for water to flow down, are other benefits that make these machines incomparable and priceless in this fields. - Laser levelling machines for earth-moving:
the first-rate performance of the Mara levellers permits 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 tilt, are reached. - 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 preciseness, 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 tilt and also a fabulous aesthetic result are ensured. - Laser grader machines for roads:
in this area, important results are reached 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 benefits, for example specialized labor is no longer needed, on top to the fact that the use of fine materials is reduced.
