Mara Laser is a business company that for 30 years and more has been analyzing, producing and marketing laser and GPS controlled levellers, turning towards buyers in about 30 nations all over the world.
Thanks to GPS and laser control technologies, we can get to significant results in many sectors of use: 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 capacity in more than one situations: from the machine running velocity, to a total trustworthiness and certainty of the result.
The technology used by Mara is what makes it unique, 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 continually 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 placed on a tripod that observes the natural inclination of the soil and sends the signal to the receiver, which is instead positioned on the machine itself.
The laser beam, as it is one of its internal characteristics, enables very high preciseness even over long land portions. After picking up the signal, a technologically perfectioned rotating pentaprism, positioned on these machines, returns an ideal planning 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, manufactured by Mara Laser, guarantee the levellers will be able to move on any kind of soil and receive the 360° signal, even if it could be low or experiences interference.
On the laser levelling machine, moreover, there is a control system to annul 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 set the position of the laser levelling machine and the height of the blade.
The levellers, that adopt 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 minor accuracy than laser technology: GPS systems are subject to fluctuations as it is one of 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 agricoltural ground and building constructions.
Integrated laser + GPS system
Mara Laser has created and manufactured an integrated system that adds the precision of laser technology with the potential of GPS, the right one for tough soil.
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 set the height of the tractor leveller and the place of the blade itself.
The creation of the 3D map of the soil enables to highlight the land sections that has to be scraped, the loading areas, the starting point, and the best route that enables 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 important increase of the arable land sections. They enable a reduction in the amount of water used, an increased production, a less use of chemicals, as well as seeds. The lowering 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 reduced deflections (max 4 mm) and to annul cavities and gaps that would, afterwords, be filled with concrete. The lowering 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 incomparable in this areas.
- Laser levelling machines for earth-moving:
the first-rate 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 inclination, are reached.
- Laser levelling machine for sportsground:
this type of technology can be utilized 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, reduced size and easy handling of Mara 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 area, important results are reached thanks to the skills 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 important plus, for example specialized labor is no longer necessary, besides to the fact that the use of fine materials is reduced.
