Mara Laser is a business company that for over 30 years has been examining, producing and marketing 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 considerable results in different sectors of use: from agricultural soil to sportsground, from building constructions to road excavations, from landscaping to ground scraping.
Mara’s levellers ensure a series of advantages and high capacity in more than one situations: from the machine operating speed regime, to a total trustworthiness 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 system technologies provide an unrivaled 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 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 gradient of the land and sends the signal to the receiver, which is instead positioned on the machine itself.
The laser beam, for its own characteristics, enables very high preciseness even over long sections of land. After obtaining 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 has an important role, 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 kind of soil and receive the 360° signal, even if it could be poor or it goes through interference.
On the laser levelling machine, moreover, there is a control system to annul external interference. It cuts wind rumble, automatically reaches 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 adopt this technology, obtain the laser signal from the satellites: even in this situation the program is represented by the signal and reproduced on the land.
Lately, thanks to technological progress and the use of dedicated software, an accuracy of ± 10 mm has been obtained, 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 elasticity of use, mostly 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 created and manufactured an integrated system that adds the precision of laser technology with the potential of GPS, the right one 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 precise spot of the leveller. Hence, 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 land enables to highlight the land portions that has to be scraped, the loading areas, the section where to begin, and the best way that allows to make the best work possible, with both the tractor and the leveller in the right position.
Hence, the operator will have instant instructions through the constant updating of the data by the system.
Fields of application
The considerable preciseness and elasticity of the levellers manufactured by Mara Laser secure their use in more than one fields:
- Laser levelling machines for agriculture:
Mara’s laser levellers, among the different benefits secure a important increase of the arable land portions. 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 times, moreover, makes the use of these machines a sure investment.
- Laser levelling machines for construction:
Mara Laser gives a perfect precision to obtain ground floors with very contained deflections (max 4 mm) and to annul cavities and gaps that would, later, be filled with concrete. The lowering of work times and the possibility of obtaining a perfect inclinatoin for water to flow down, are other benefits that make these machines priceless and priceless in this fields.
- Laser levelling machines for earth-moving:
the superbe performance of the Mara levellers enables to move large amount 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 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 preciseness, contained size and easy handling of Mara laser levellers, it is also feasible to work for the maintenance of green spaces. In this way, the right gradient and also a fabulous aesthetic result are ensured.
- Laser grader machines for roads:
in this field, important results are achieved 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 benefits, for example specialized labor is no longer needed, besides to the fact that the use of fine materials is reduced.
