Mara Laser is a business company that for 30 years and more has been examining, making and trading laser and GPS controlled laser levellers, calling on buyers in about 30 states all over the world.
Thanks to GPS and laser control technologies, it is feasible to achieve outstanding results in many sectors of utility: from agricoltural ground to sportsground, from building constructions to road excavations, from landscaping to soil scraping.
Mara’s levellers ensure a series of returns and high productivity in more than one situations: from the machine functioning velocity, to a total affidability and assurance 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 system technologies provide an unrivaled performance, in particular 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 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 gradient of the land and communicates the signal to the receiver, which is instead positioned on the machine itself.
The laser beam, beacuse of its own characteristics, permits very high preciseness even over long land portions. After getting the signal, a technologically perfectioned rotating pentaprism, positioned on these machines, returns an ideal pianification for the leveller to follow while functioning.
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 work on any type fo ground and receive the 360° signal, though it could be low or experiences interference.
On the laser leveller, besides, there is a control system to remove external interference. It cuts wind rumble, automatically captures the signal and regulates the power of the tractor.
GPS system technology
GPS technology, however, is used to regulate the position of the laser leveller and the height of the blade.
The levellers, that adopt this technology, obtain the laser signal from the satellites: even in this situation the pianification is defined by the signal and reproduced on the land.
Nowadays, thanks to technological progress 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 adaptability of use, in particular when this technology is used to work on large land sections with more than one inclinations, such as agricoltural ground and building constructions.
Integrated laser + GPS system
Mara Laser has created and made an integrated system that connects the precision of laser technology with the potential of GPS, the right one for tough land.
The higher preciseness of the laser signal represents 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 land permits to highlight the land sections that has to be scraped, the loading areas, the point where to start, and the best way that allows to do the greatest job possible, with both the tractor and the leveller in the right position.
Thus, the operator will have instant instructions through the constant updating of the data by the system.
Fields of application
The outstanding preciseness and adaptability of the levellers made by Mara Laser assure their use in more than one areas:
- Laser levelling machines for agriculture:
Mara’s laser levellers, among the many plus assure a important increase of the arable land sections. They enable 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, furthermore, makes the use of these machines a sure investment.
- Laser levelling machines for construction:
Mara Laser gives an absolute 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 an absolute perfect inclinatoin for water to flow down, are other plus that make these machines worthy and priceless in this areas.
- 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 preciseness in creating the horizontal plan and gradient, are attained.
- Laser levelling machine for sportsground:
this type of technology can be used very well in this area as it enables to level even existing sectors, repairing slope without replacing the lawn.
- Laser levelling machines for greenhouses:
thanks to the preciseness, contained 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 great aesthetic result are assured.
- Laser grader machines for roads:
in this area, important results are attained thanks to the capability 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 important plus, for example specialized labor is no longer needed, on top to the fact that the use of fine materials is reduced.
