Mara Laser is a business company that for over 30 years has been examining, producing and trading laser and GPS controlled laser levellers, turning towards clients in about 30 states all over the world.
Thanks to GPS and laser control technologies, we can reach significant 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 productivity in more than one situations: from the machine operating speed regime, to a total affidability and assurance of the result.
The technology used by Mara is what makes it unique, and the results acquired all over the world witness this. Laser and GPS receiver technologies give an unrivaled 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 laser leveller, 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 examines the natural inclination of the land and communicates the signal to the receiver, which is instead positioned on the machine itself.
The laser beam, for its own characteristics, permits very high preciseness even over long sections of land. After getting the signal, a technologically perfectioned rotating pentaprism, positioned on these machines, returns an ideal program 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 type fo ground and receive the 360° signal, though it could be poor or it is subjected to interference.
On the laser leveller, moreover, there is a control system to remove external interference. It cuts wind sound, automatically captures the signal and settles the power of the tractor.
GPS receiver technology
GPS technology, however, is used to regulate 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 program is represented by the signal and reproduced on the land.
Nowadays, thanks to technological advancement and the use of dedicated software, an accuracy of ± 10 mm has been obtained, even though this technology offers minor accuracy than laser technology: GPS systems are subject to fluctuations for the periodic change of constellation of the satellites.
In any case, the minor preciseness is compensated by the wide elasticity of use, in particular when this technology is used to work on large land sections with more than one inclinations, such as agricultural soil and building constructions.
Integrated laser + GPS system
Mara Laser has created and manufactured an integrated system that matches the precision of laser technology with the potential of GPS, suitable for harsh 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 route 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 significant preciseness and elasticity of the levellers manufactured 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 sections. They permits 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, moreover, 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 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 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 superbe 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 inclination, are attained.
- 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 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 doable to work for the maintenance of green spaces. In this way, the right inclination and also a fabulous aesthetic result are assured.
- Laser grader machines for roads:
in this field, important results are attained thanks to the capability of the Mara’s laser graders to perform the same job as the motor grader, with minor costs and more convenient times. In addition, there are key plus, for example specialized labor is no longer needed, besides to the fact that the use of fine materials is reduced.
