Mara Laser is a business company that for over 30 years has been analyzing, producing and marketing laser and GPS controlled levellers, turning towards buyers in about 30 states everywhere in the world.
Thanks to GPS and laser control technologies, we can reach important results in different sectors of use: from agricultural soil to sport courts, from building constructions to road excavations, from landscaping to soil scraping.
Mara’s levellers ensure a series of returns and high capacity in various situations: from the machine running speed regime, to a total trustworthiness and certainty of the result.
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 provide an unique performance, mostly 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 leveller, the laser beam transmitter and the laser beam receiver are parts of the laser control system for levelling.
The transmitter is positioned on a tripod that examines the natural inclination of the land and communicates the signal to the receiver, which is instead put on the machine itself.
The laser beam, beacuse of its internal characteristics, permits very high accuracy even over long sections of land. After getting the signal, a technologically perfectioned rotating pentaprism, put on these machines, gives back 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 is subjected to interference.
On the leveller, moreover, there is a control system to annul external interference. It decreases wind sound, automatically intercepts the signal and settles the power of the tractor.
GPS system technology
GPS technology, after all, is used to settle the position of the leveller and the height of the blade.
The levellers, that adopt this technology, get the laser signal from the satellites: even in this situation the program 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 minor accuracy than laser technology: GPS systems are subject to fluctuations beacuse of the periodic change of constellation of the satellites.
In any case, the minor accuracy is compensated by the wide adaptability of use, mostly when this technology is used to work on large parts with various inclinations, such as agricultural soil and building constructions.
Integrated laser + GPS system
Mara Laser has created and made an integrated system that adds the precision of laser technology with the potential of GPS, the right one for harsh land.
The higher accuracy of the laser signal lays out the plan within a radius of 1300 meters, while the GPS system communicates the precise spot of the leveller. Thus, the Mara system can settle the height of the tractor leveller and the precise spot of the blade itself.
The creation of the 3D map of the land permits to highlight the parts 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.
Thus, the operator will have immediate instructions through the constant updating of the data by the system.
Fields of application
The important accuracy and adaptability of the levellers made by Mara Laser assure their use in various fields:
- Laser levelling machines for agriculture:
Mara’s laser levellers, among the different conveniences assure a key increase of the arable parts. 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 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 annul cavities and gaps that would, later, be filled with concrete. The decrease of work hours and the possibility of obtaining a perfect inclinatoin for water to flow down, are other conveniences that make these machines worthy and priceless in this fields.
- Laser levelling machines for earth-moving:
the superbe performance of the Mara levellers permits to move large quantity of soil very quickly and with low power. In this way, shorter work hours, lower costs and greater accuracy in creating the horizontal plan and inclination, are achieved.
- 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 accuracy, reduced size and easy handling of Mara levellers, it is also feasible to work for the maintenance of green spaces. In this way, the right inclination and also a great aesthetic result are assured.
- Laser grader machines for roads:
in this field, important results are achieved 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 conveniences, for example specialized labor is no longer necessary, besides to the fact that the use of fine materials is reduced.
