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 clients in about 30 states everywhere in the world.
Thanks to GPS and laser control technologies, it is feasible to achieve important results in many sectors of use: from agricultural soil to sport facilities, 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 speed regime, to a total trustworthiness and certainty of the result.
The technology used by Mara is what makes it unbeatable, and the results obtained all over the world testify 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 parts of the laser control system for levelling.
The transmitter is put on a tripod that sees the natural tilt of the soil and communicates the signal to the receiver, which is instead put on the machine itself.
The laser beam, beacuse of its own characteristics, permits very high preciseness even over long sections of land. After picking up the signal, a technologically perfectioned rotating pentaprism, put on these machines, gives back an ideal planning for the leveller to follow while running.
The receiver also has an important role, 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 kind of soil and receive the 360° signal, though it could be low or experiences interference.
On the laser levelling machine, moreover, there is a control system to remove external interference. It decreases wind sound, automatically reaches the signal and sets the power of the tractor.
GPS receiver 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 implement this technology, obtain the laser signal from the satellites: even in this situation the planning is represented 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 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 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, proper for tough 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. Thus, 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 soil permits to highlight the land portions that has to be scraped, the loading areas, the starting point, 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 prompt instructions through the constant updating of the data by the system.
Fields of application
The important preciseness and elasticity of the levellers made by Mara Laser ensure their use in more than one areas:
- Laser levelling machines for agriculture:
Mara’s laser levellers, among the many plus ensure a key increase of the arable land portions. They enable a reduction in the amount of water used, they can provide more abundant harvest, a considerable reduction of chemicals used, as well as seeds. The decrease in work times, furthermore, makes the use of these machines a sure investment.
- Laser levelling machines for construction:
Mara Laser provides an absolute perfect precision to obtain ground floors with very reduced deflections (max 4 mm) and to remove cavities and gaps that would, later, be filled with concrete. The decrease of work times and the possibility of obtaining an absolute perfect slope for water to flow down, are other plus that make these machines incomparable and priceless in this areas.
- 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 times, lower costs and greater preciseness in creating the horizontal plan and tilt, are attained.
- Laser levelling machine for sportsground:
this type of technology can be utilized 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 preciseness, 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 tilt and also a fabulous aesthetic result are secured.
- Laser grader machines for roads:
in this area, important results are attained thanks to the skills 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, besides to the fact that the use of fine materials is reduced.
