Mara Laser is a business company that for over 30 years has been examining, making and trading laser and GPS controlled levellers, calling on buyers in about 30 states all over the world.
Thanks to GPS and laser control technologies, we can get to outstanding results in different areas of utility: from agricoltural ground 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 various situations: from the machine functioning velocity, 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 receiver 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 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 examines the natural inclination 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 land portions. After picking up the signal, a technologically perfectioned rotating pentaprism, located on these machines, returns an ideal pianification for the leveller to follow while functioning.
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 move on any kind of soil and receive the 360° signal, even if it could be poor or experiences interference.
On the laser levelling machine, also, there is a control system to remove external interference. It decreases wind sound, automatically reaches the signal and regulates 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 implement this technology, perceive the laser signal from the satellites: even in this situation the pianification is represented by the signal and reproduced on the soil.
Lately, 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 for the periodic change of constellation of the satellites.
In any case, the minor preciseness is compensated by the wide elasticity of use, mostly when this technology is used to work on large land portions with various inclinations, such as agricoltural ground and building constructions.
Integrated laser + GPS system
Mara Laser has produced and manufactured an integrated system that connects 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 location of the leveller. Thus, the Mara system can set the height of the tractor leveller and the location of the blade itself.
The creation of the 3D map of the soil enables to highlight the land portions 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 instant instructions through the constant updating of the data by the system.
Fields of application
The outstanding preciseness and elasticity of the levellers manufactured by Mara Laser assure their use in various areas:
- Laser levelling machines for agriculture:
Mara’s laser levellers, among the different conveniences assure a important increase of the arable land portions. They permits a reduction in the amount of water used, an increased production, a considerable reduction of chemicals used, as well as seeds. The decrease in work times, 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 times and the possibility of obtaining an absolute perfect slope for water to flow down, are other conveniences that make these machines priceless and priceless in this areas.
- Laser levelling machines for earth-moving:
the first-rate 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 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 areas, repairing soil depressions without replacing the lawn.
- Laser levelling machines for greenhouses:
thanks to the preciseness, contained 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 ensured.
- Laser grader machines for roads:
in this field, important results are achieved 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 conveniences, for example specialized labor is no longer necessary, besides to the fact that the use of fine materials is reduced.
