Mara Laser is a business activity that for 30 years and more has been examining, producing and trading laser and GPS controlled laser levelling machines, turning towards buyers in about 30 states everywhere in the world.
Thanks to GPS and laser control technologies, we can reach outstanding results in different areas of use: from agricultural soil to sport courts, from building constructions to road excavations, from landscaping to soil scraping.
Mara’s levellers ensure a series of returns and high capacity in various 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 unique, and the results obtained all over the world testify this. Laser and GPS system technologies provide an unrivaled performance, mostly when they are combined.
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 parts of the laser control system for levelling.
The transmitter is located on a tripod that examines the natural inclination of the soil and sends the signal to the receiver, which is instead mounted on the machine itself.
The laser beam, beacuse of its internal characteristics, permits very high preciseness even over long sections of land. After getting the signal, a technologically perfectioned rotating pentaprism, mounted on these machines, returns an ideal pianification 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 work on any kind of ground and receive the 360° signal, even if it could be low or experiences interference.
On the laser leveller, moreover, there is a control system to annul external interference. It decreases wind sound, automatically reaches the signal and settles the power of the tractor.
GPS system technology
GPS technology, after all, 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 pianification is defined by the signal and reproduced on the soil.
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 preciseness is compensated by the wide elasticity of use, mostly when this technology is used to work on large land portions 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, suitable for harsh soil.
The higher preciseness of the laser signal shows the plan within a radius of 1300 meters, while the GPS system communicates the place of the leveller. Hence, the Mara system can settle the height of the tractor leveller and the place 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 do the greatest job possible, with both the tractor and the leveller in the right position.
Hence, the operator will have instant instructions through the constant updating of the data by the system.
Fields of application
The outstanding preciseness and elasticity of the levellers manufactured by Mara Laser ensure their use in various fields:
- Laser levelling machines for agriculture:
Mara’s laser levellers, among the different 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 times, 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 reduced deflections (max 4 mm) and to annul cavities and gaps that would, afterwords, be filled with concrete. The decrease of work times 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 superbe performance of the Mara levellers permits to move large amount of soil very quickly and with low power. In this way, shorter work times, lower costs and greater preciseness in creating the horizontal plan and inclination, are attained.
- Laser levelling machine for sportsground:
this type of technology can be utilized very well in this field as it enables to level even existing areas, repairing slope without replacing the lawn.
- Laser levelling machines for greenhouses:
thanks to the preciseness, 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 inclination and also a great aesthetic result are secured.
- Laser grader machines for roads:
in this field, important results are attained thanks to the skills 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.
