Mara Laser is a business company that for 30 years and more has been analyzing, making and marketing laser and GPS controlled laser levelling machines, turning towards clients in about 30 states everywhere in the world.
Thanks to GPS and laser control technologies, we can reach outstanding results in many sectors of use: from agricoltural ground to sport facilities, 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 operating velocity, to a total trustworthiness and assurance of the result.
Mara’s technology
The technology used by Mara is what makes it unbeatable, and the results obtained all over the world testify this. Laser and GPS system technologies give an unique performance, in particular when they are combined.
Laser technology
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 observes the natural gradient of the soil and sends the signal to the receiver, which is instead located on the machine itself.
The laser beam, for its internal characteristics, enables very high preciseness even over long sections of land. After picking up the signal, a technologically perfectioned rotating pentaprism, located on these machines, gives back 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, 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 poor or experiences interference.
On the laser levelling machine, moreover, there is a control system to remove external interference. It decreases wind rumble, automatically intercepts the signal and regulates the power of the tractor.
GPS system 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 implement this technology, get the laser signal from the satellites: even in this situation the program is defined 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 reached up, even though this technology offers poorer accuracy than laser technology: GPS systems are subject to fluctuations for 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 matches the precision of laser technology with the potential of GPS, suitable 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 precise spot of the leveller. Therefor, the Mara system can set the height of the tractor leveller and the precise spot 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 section where to begin, and the best way that enables to make the best work 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 outstanding 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 many plus ensure a important increase of the arable land sections. They permits 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 lowering in work times, besides, 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 reduced deflections (max 4 mm) and to remove cavities and gaps that would, afterwords, be filled with concrete. The lowering of work times and the possibility of obtaining an absolute perfect slope for water to flow down, are other plus that make these machines priceless 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 times, 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 field 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 laser levelling machines, 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 ensured. - Laser grader machines for roads:
in this field, important results are attained thanks to the skills 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, besides to the fact that the use of fine materials is reduced.
