Mara Laser is a business activity that for 30 years and more has been analyzing, producing and trading laser and GPS controlled laser levellers, turning towards buyers in about 30 nations all over the world.
Thanks to GPS and laser control technologies, we can get to significant results in many sectors of use: from agricultural soil to sportsground, 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 operating velocity, to a total affidability and certainty of the result.
The technology used by Mara is what makes it unbeatable, and the results acquired all over the world witness this. Laser and GPS receiver 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 leveller, the laser beam transmitter and the laser beam receiver are the elements of the laser control system for levelling.
The transmitter is located on a tripod that examines the natural inclination of the land and communicates the signal to the receiver, which is instead put on the machine itself.
The laser beam, for its own characteristics, permits very high accuracy even over long sections of land. After obtaining the signal, a technologically perfectioned rotating pentaprism, put on these machines, returns an ideal planning 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, made 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 it is subjected to interference.
On the leveller, moreover, there is a control system to annul external interference. It cuts wind rumble, 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 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 planning is defined by the signal and reproduced on the land.
Nowadays, 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 accuracy is compensated by the wide adaptability of use, mostly when this technology is used to work on large land portions with more than one inclinations, such as agricultural soil 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 land.
The higher accuracy of the laser signal lays out 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 land permits to highlight the land portions that has to be scraped, the loading areas, the starting point, and the best route that enables to make the best work 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 accuracy and adaptability of the levellers made by Mara Laser ensure their use in more than one fields:
- Laser levelling machines for agriculture:
Mara’s laser levellers, among the many plus ensure 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 decrease in work hours, moreover, 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 annul cavities and gaps that would, later, be filled with concrete. The decrease of work hours and the possibility of obtaining a perfect inclinatoin for water to flow down, are other plus that make these machines incomparable and incomparable in this fields.
- 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 hours, lower costs and greater accuracy 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 makes possible to level even existing sectors, repairing slope without replacing the lawn.
- Laser levelling machines for greenhouses:
thanks to the accuracy, contained 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 ensured.
- 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 plus, for example specialized labor is no longer needed, besides to the fact that the use of fine materials is reduced.
