Mara Laser is a business company that for over 30 years has been examining, producing and marketing laser and GPS controlled laser levellers, turning towards 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 speed regime, to a total affidability and guarantee of the final success.
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 give an unrivaled 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 leveller, the laser beam transmitter and the laser beam receiver are parts of the laser control system for levelling.
The transmitter is placed on a tripod that sees the natural inclination of the land and sends the signal to the receiver, which is instead put on the machine itself.
The laser beam, as it is one of its own characteristics, enables very high preciseness even over long sections of land. After picking up the signal, a technologically perfectioned rotating pentaprism, put on these machines, returns an ideal program 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 type fo ground and receive the 360° signal, even though it could be poor or experiences interference.
On the leveller, also, there is a control system to remove external interference. It lowers wind rumble, automatically reaches the signal and settles the power of the tractor.
GPS system technology
GPS technology, after all, is used to regulate 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 program 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 as it is one 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 land portions with more than one inclinations, such as agricoltural ground and building constructions.
Integrated laser + GPS system
Mara Laser has produced and manufactured an integrated system that adds the precision of laser technology with the potential of GPS, suitable for tough land.
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. Thus, the Mara system can regulate the height of the tractor leveller and the location of the blade itself.
The creation of the 3D map of the land enables to highlight the land portions that has to be scraped, the loading areas, the starting point, and the best route that allows to do the greatest job possible, with both the tractor and the leveller in the right position.
Thus, the operator will have immediate instructions through the constant updating of the data by the system.
Fields of application
The important preciseness and elasticity of the levellers manufactured by Mara Laser assure their use in more than one areas:
- Laser levelling machines for agriculture:
Mara’s laser levellers, among the many conveniences assure a key increase of the arable land portions. 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 hours, furthermore, makes the use of these machines a sure investment.
- Laser levelling machines for construction:
Mara Laser gives an absolute 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 hours 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 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 hours, lower costs and greater preciseness in creating the horizontal plan and inclination, are reached.
- Laser levelling machine for sportsground:
this type of technology can be used very well in this area as it makes possible to level even existing sectors, 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 inclination and also a fabulous aesthetic result are secured.
- Laser grader machines for roads:
in this area, important results are reached thanks to the capability 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.
