Mara Laser is a business company that for 30 years and more has been examining, making and trading laser and GPS controlled laser levelling machines, turning towards buyers in about 30 states all over the world.
Thanks to GPS and laser control technologies, it is feasible to achieve 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 operating velocity, to a total affidability 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 unique performance, in particular when they are used together.
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 positioned on a tripod that observes the natural inclination of the land and sends the signal to the receiver, which is instead put on the machine itself.
The laser beam, beacuse of its own characteristics, enables very high preciseness even over long sections of land. After picking up the signal, a technologically perfectioned rotating pentaprism, put on these machines, gives back an ideal planning 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, manufactured by Mara Laser, guarantee the levellers will be able to work on any type fo ground and receive the 360° signal, though it could be poor or it goes through interference.
On the laser levelling machine, besides, there is a control system to remove external interference. It cuts wind sound, automatically intercepts the signal and regulates the power of the tractor.
GPS system technology
GPS technology, however, is used to regulate the position of the laser levelling machine and the height of the blade.
The levellers, that implement this technology, obtain the laser signal from the satellites: even in this situation the planning is represented by the signal and reproduced on the land.
Nowadays, thanks to technological advancement 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 beacuse 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 produced and manufactured an integrated system that matches the precision of laser technology with the potential of GPS, the right one for tough land.
The higher preciseness of the laser signal shows the plan within a radius of 1300 meters, while the GPS system communicates the location of the leveller. Thus, the Mara system can regulate the height of the tractor leveller and the location of the blade itself.
The creation of the 3D map of the land enables to highlight the land sections that has to be scraped, the loading areas, the starting point, and the best way that allows 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 fields:
- Laser levelling machines for agriculture:
Mara’s laser levellers, among the many benefits ensure a key 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, moreover, 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 contained 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 benefits that make these machines worthy and priceless in this fields.
- 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 reached.
- Laser levelling machine for sportsground:
this type of technology can be used very well in this field as it makes possible to level even existing sectors, repairing soil depressions without replacing the lawn.
- Laser levelling machines for greenhouses:
thanks to the preciseness, contained 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 inclination and also a great aesthetic result are assured.
- Laser grader machines for roads:
in this field, 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 key benefits, for example specialized labor is no longer necessary, besides to the fact that the use of fine materials is reduced.
