Mara Laser is a business activity that for 30 years and more has been examining, making and trading laser and GPS controlled levellers, calling on clients in about 30 nations all over the world.
Thanks to GPS and laser control technologies, it is feasible to achieve considerable results in different areas of utility: from agricultural soil to sport courts, from building constructions to road excavations, from landscaping to ground scraping.
Mara’s levellers ensure a series of advantages and high capacity in various situations: from the machine operating velocity, to a total trustworthiness and assurance of the result.
The technology used by Mara is what makes it unique, and the results acquired all over the world witness this. Laser and GPS system technologies provide an unique performance, in particular when they are used together.
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 put on a tripod that examines the natural inclination of the soil and sends the signal to the receiver, which is instead located on the machine itself.
The laser beam, beacuse of its internal characteristics, enables very high preciseness even over long land portions. After picking up the signal, a technologically perfectioned rotating pentaprism, located on these machines, returns 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, manufactured 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 poor or experiences interference.
On the laser leveller, also, there is a control system to remove external interference. It decreases wind rumble, automatically intercepts the signal and sets the power of the tractor.
GPS system technology
GPS technology, however, is used to set 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 pianification is represented by the signal and reproduced on the soil.
Lately, thanks to technological advancement and the use of dedicated software, an accuracy of ± 10 mm has been reached up, even though this technology offers minor accuracy than laser technology: GPS systems are subject to fluctuations beacuse of the periodic change of constellation of the satellites.
In any case, the minor preciseness is compensated by the wide adaptability of use, in particular when this technology is used to work on large land portions with various inclinations, such as agricultural soil and building constructions.
Integrated laser + GPS system
Mara Laser has created and manufactured an integrated system that matches the precision of laser technology with the potential of GPS, suitable for tough soil.
The higher preciseness of the laser signal represents the plan within a radius of 1300 meters, while the GPS system communicates the place of the leveller. Therefor, the Mara system can set the height of the tractor leveller and the place of the blade itself.
The creation of the 3D map of the soil enables to highlight the land portions that has to be scraped, the loading areas, the point where to start, and the best route that enables to do the greatest job possible, with both the tractor and the leveller in the right position.
Therefor, the operator will have immediate instructions through the constant updating of the data by the system.
Fields of application
The considerable preciseness and adaptability of the levellers manufactured by Mara Laser secure their use in various areas:
- Laser levelling machines for agriculture:
Mara’s laser levellers, among the different benefits secure a key increase of the arable land portions. 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 times, furthermore, 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 contained deflections (max 4 mm) and to remove 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 benefits that make these machines priceless and incomparable 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 times, lower costs and greater preciseness in creating the horizontal plan and inclination, are attained.
- Laser levelling machine for sportsground:
this type of technology can be used 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 preciseness, contained size and easy handling of Mara levellers, it is also feasible to work for the maintenance of green spaces. In this way, the right inclination and also a fabulous aesthetic result are assured.
- Laser grader machines for roads:
in this field, important results are attained thanks to the capacity of the Mara’s laser graders to provide the same job as the motor grader, with minor costs and more convenient times. In addition, there are key benefits, for example specialized labor is no longer necessary, on top to the fact that the use of fine materials is reduced.
