Mara Laser is a business activity that for 30 years and more has been analyzing, making and trading laser and GPS controlled laser levellers, turning towards buyers in about 30 states everywhere in the world.
Thanks to GPS and laser control technologies, we can reach significant results in different areas 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 productivity in more than one situations: from the machine running speed regime, 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 receiver technologies provide an unique performance, in particular when they are combined.
Laser technology is applied to the levellers in a way that without stopping synchronize the height of the blade.
The leveller, the laser beam transmitter and the laser beam receiver are the elements of the laser control system for levelling.
The transmitter is placed on a tripod that examines the natural gradient of the land and sends the signal to the receiver, which is instead located on the machine itself.
The laser beam, for its own characteristics, enables very high preciseness even over long land portions. After getting the signal, a technologically perfectioned rotating pentaprism, located on these machines, returns 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 low or it goes through interference.
On the leveller, also, there is a control system to remove external interference. It cuts wind sound, automatically intercepts the signal and settles the power of the tractor.
GPS receiver technology
GPS technology, after all, is used to regulate the position of the 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 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 less accuracy than laser technology: GPS systems are subject to fluctuations for the periodic change of constellation of the satellites.
In any case, the less preciseness is compensated by the wide adaptability of use, in particular 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, the right one for tough land.
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. Therefor, 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 enables to highlight the land portions that has to be scraped, the loading areas, the point where to start, and the best route that enables to do the greatest job 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 significant preciseness and adaptability 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 different conveniences ensure a important increase of the arable land portions. They enable a reduction in the amount of water used, an increased production, a considerable reduction of chemicals used, as well as seeds. The decrease in work hours, moreover, 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 remove cavities and gaps that would, later, be filled with concrete. The decrease of work hours and the possibility of obtaining a perfect slope for water to flow down, are other conveniences that make these machines priceless and incomparable in this areas.
- Laser levelling machines for earth-moving:
the superbe performance of the Mara levellers enables to move large quantity 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 reached.
- 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 areas, repairing soil depressions 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 doable to work for the maintenance of green spaces. In this way, the right gradient and also a great aesthetic result are ensured.
- Laser grader machines for roads:
in this area, important results are reached thanks to the capacity of the Mara’s laser graders to provide the same job as the motor grader, with less costs and more convenient times. In addition, there are important conveniences, for example specialized labor is no longer necessary, besides to the fact that the use of fine materials is reduced.
