Mara Laser is a business activity that for over 30 years has been analyzing, producing and marketing laser and GPS controlled laser levelling machines, turning towards buyers in about 30 nations all over the world.
Thanks to GPS and laser control technologies, it is feasible to achieve important results in many sectors of utility: 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 capacity in various situations: from the machine operating velocity, to a total affidability and assurance of the result.
Mara’s technology
The technology used by Mara is what makes it unbeatable, and the results obtained all over the world testify this. Laser and GPS system technologies give an unique performance, mostly when they are used together.
Laser technology
Laser technology is applied to the levellers in a way that without stopping synchronize the height of the blade.
The laser levelling machine, 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 sees the natural tilt of the land and communicates the signal to the receiver, which is instead mounted on the machine itself.
The laser beam, as it is one of its own characteristics, permits very high accuracy even over long land portions. After picking up the signal, a technologically perfectioned rotating pentaprism, mounted on these machines, gives back an ideal program 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, manufactured by Mara Laser, guarantee the levellers will be able to work on any kind of soil and receive the 360° signal, though it could be low or it goes through interference.
On the laser levelling machine, besides, there is a control system to remove external interference. It cuts wind sound, automatically reaches the signal and regulates the power of the tractor.
GPS system technology
GPS technology, after all, is used to regulate the position of the laser levelling machine and the height of the blade.
The levellers, that adopt this technology, perceive the laser signal from the satellites: even in this situation the program is defined 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 poorer 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 poorer accuracy is compensated by the wide adaptability of use, mostly when this technology is used to work on large land sections with various inclinations, such as agricultural soil 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, proper 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 place of the leveller. Hence, the Mara system can regulate the height of the tractor leveller and the place of the blade itself.
The creation of the 3D map of the land permits to highlight the land sections 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.
Hence, the operator will have prompt instructions through the constant updating of the data by the system.
Fields of application
The important accuracy and adaptability of the levellers manufactured by Mara Laser ensure their use in various areas:
- Laser levelling machines for agriculture:
Mara’s laser levellers, among the many plus ensure a key increase of the arable land sections. They permits a reduction in the amount of water used, they can provide more abundant harvest, 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 slope for water to flow down, are other plus that make these machines worthy 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 accuracy 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 sectors, repairing soil depressions without replacing the lawn. - Laser levelling machines for greenhouses:
thanks to the accuracy, reduced size and easy handling of Mara laser levelling machines, 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 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 poorer costs and more convenient times. In addition, there are key plus, for example specialized labor is no longer necessary, on top to the fact that the use of fine materials is reduced.
