Mara Laser is a business activity that for over 30 years has been examining, making and marketing laser and GPS controlled laser levellers, calling on buyers in about 30 states everywhere in the world.
Thanks to GPS and laser control technologies, it is feasible to achieve considerable results in many sectors of utility: from agricultural soil to sportsground, from building constructions to road excavations, from landscaping to soil scraping.
Mara’s levellers ensure a series of advantages and high capacity in more than one situations: from the machine running speed regime, 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 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 laser levelling machine, 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 observes the natural gradient of the land and sends the signal to the receiver, which is instead located on the machine itself.
The laser beam, beacuse of its internal characteristics, permits very high accuracy even over long sections of land. After obtaining the signal, a technologically perfectioned rotating pentaprism, located 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, manufactured by Mara Laser, guarantee the levellers will be able to work on any kind of soil and receive the 360° signal, even though it could be low or experiences interference.
On the laser levelling machine, moreover, there is a control system to annul external interference. It decreases wind rumble, automatically intercepts the signal and settles the power of the tractor.
GPS receiver technology
GPS technology, however, is used to set the position of the laser levelling machine and the height of the blade.
The levellers, that adopt this technology, get the laser signal from the satellites: even in this situation the program is illustrated by the signal and reproduced on the land.
Lately, 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 beacuse of the periodic change of constellation of the satellites.
In any case, the poorer accuracy is compensated by the wide elasticity of use, mostly when this technology is used to work on large parts with more than one 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 shows the plan within a radius of 1300 meters, while the GPS system communicates the place of the leveller. Therefor, the Mara system can set 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 parts that has to be scraped, the loading areas, the section where to begin, and the best way that enables to make the best work possible, with both the tractor and the leveller in the right position.
Therefor, the operator will have immediate instructions through the constant updating of the data by the system.
Fields of application
The considerable accuracy and elasticity of the levellers manufactured 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 parts. They permits a reduction in the amount of water used, an increased production, a considerable reduction of chemicals used, as well as seeds. The lowering in work hours, besides, 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 annul cavities and gaps that would, later, be filled with concrete. The lowering 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 priceless in this fields.
- Laser levelling machines for earth-moving:
the fine 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 gradient, are achieved.
- Laser levelling machine for sportsground:
this type of technology can be utilized very well in this field as it makes possible 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 levellers, it is also feasible to work for the maintenance of green spaces. In this way, the right gradient and also a fabulous aesthetic result are secured.
- Laser grader machines for roads:
in this field, important results are achieved thanks to the capacity of the Mara’s laser graders to provide 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, besides to the fact that the use of fine materials is reduced.
