Mara Laser is a business activity that for over 30 years has been analyzing, producing and marketing laser and GPS controlled laser levellers, calling on clients in about 30 states everywhere in the world.
Thanks to GPS and laser control technologies, it is feasible to achieve significant results in different areas of utility: 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 productivity 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 system technologies provide 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 leveller, the laser beam transmitter and the laser beam receiver are the elements of the laser control system for levelling.
The transmitter is put on a tripod that sees the natural inclination of the land and communicates the signal to the receiver, which is instead located 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, located on these machines, gives back an ideal pianification for the leveller to follow while running.
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 move on any kind of ground and receive the 360° signal, though it could be low or it is subjected to interference.
On the leveller, besides, there is a control system to remove external interference. It decreases wind sound, automatically intercepts the signal and regulates the power of the tractor.
GPS system technology
GPS technology, however, is used to regulate the position of the leveller and the height of the blade.
The levellers, that adopt 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.
Nowadays, 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 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 produced and made an integrated system that matches the precision of laser technology with the potential of GPS, the right one for harsh land.
The higher preciseness of the laser signal represents the plan within a radius of 1300 meters, while the GPS system communicates the precise spot of the leveller. Thus, the Mara system can regulate the height of the tractor leveller and the precise spot of the blade itself.
The creation of the 3D map of the land permits to highlight the parts that has to be scraped, the loading areas, the point where to start, and the best route that allows to make the best work 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 significant preciseness and elasticity of the levellers made by Mara Laser assure their use in various areas:
- Laser levelling machines for agriculture:
Mara’s laser levellers, among the different benefits assure a key increase of the arable parts. They permits 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, furthermore, 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, later, be filled with concrete. The lowering of work times and the possibility of obtaining a perfect slope 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 first-rate performance of the Mara levellers permits to move large quantity 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 area as it enables to level even existing areas, repairing slope 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 inclination and also a great 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 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 needed, on top to the fact that the use of fine materials is reduced.
