Mara Laser is a business activity that for over 30 years has been examining, making and marketing laser and GPS controlled laser levellers, turning towards buyers in about 30 nations all over the world.
Thanks to GPS and laser control technologies, it is feasible to achieve significant results in different sectors 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 returns and high capacity in more than one situations: from the machine running velocity, 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 provide an unrivaled performance, mostly 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 the elements of the laser control system for levelling.
The transmitter is positioned on a tripod that sees the natural tilt of the soil and sends 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 land portions. After picking up the signal, a technologically perfectioned rotating pentaprism, put on these machines, gives back an ideal program 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 work on any kind of soil and receive the 360° signal, though it could be poor or experiences interference.
On the laser leveller, moreover, there is a control system to remove external interference. It decreases wind rumble, automatically captures the signal and sets the power of the tractor.
GPS system technology
GPS technology, however, is used to settle the position of the laser leveller and the height of the blade.
The levellers, that implement this technology, get the laser signal from the satellites: even in this situation the program is illustrated by the signal and reproduced on the soil.
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 elasticity 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 produced and made an integrated system that connects the precision of laser technology with the potential of GPS, suitable for tough soil.
The higher accuracy of the laser signal represents the plan within a radius of 1300 meters, while the GPS system communicates the location of the leveller. Thus, the Mara system can settle the height of the tractor leveller and the location of the blade itself.
The creation of the 3D map of the soil permits to highlight the land portions that has to be scraped, the loading areas, the point where to start, and the best way that enables to make the best work 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 significant accuracy and elasticity 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 different benefits ensure a key increase of the arable land portions. 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 hours, besides, 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, afterwords, be filled with concrete. The decrease of work hours and the possibility of obtaining a perfect slope for water to flow down, are other benefits that make these machines priceless and priceless in this fields.
- Laser levelling machines for earth-moving:
the first-rate performance of the Mara levellers permits to move large amount 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 tilt, are achieved.
- 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, 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 tilt and also a fabulous aesthetic result are secured.
- Laser grader machines for roads:
in this area, important results are achieved 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.
