Mara Laser is a business company that for 30 years and more has been analyzing, producing and trading laser and GPS controlled laser levelling machines, turning towards buyers in about 30 nations all over the world.
Thanks to GPS and laser control technologies, we can reach important results in many sectors of utility: from agricultural soil to sportsground, from building constructions to road excavations, from landscaping to soil scraping.
Mara’s levellers ensure a series of advantages and high capacity in more than one situations: from the machine functioning velocity, to a total trustworthiness and assurance of the result.
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 give an unique performance, in particular when they are combined.
Laser technology is applied to the levellers in a way that without stopping synchronize the height of the blade.
The laser leveller, the laser beam transmitter and the laser beam receiver are the elements of the laser control system for levelling.
The transmitter is put on a tripod that examines the natural tilt of the soil and sends the signal to the receiver, which is instead put on the machine itself.
The laser beam, as it is one of its internal characteristics, permits very high accuracy even over long land portions. After getting the signal, a technologically perfectioned rotating pentaprism, put on these machines, returns an ideal planning 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, made 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 low or it is subjected to interference.
On the laser leveller, besides, there is a control system to annul external interference. It lowers wind sound, automatically reaches the signal and settles the power of the tractor.
GPS system technology
GPS technology, however, is used to regulate the position of the laser leveller and the height of the blade.
The levellers, that adopt this technology, obtain the laser signal from the satellites: even in this situation the planning is defined by the signal and reproduced on the soil.
Lately, thanks to technological advancement 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 as it is one of the periodic change of constellation of the satellites.
In any case, the less accuracy is compensated by the wide adaptability of use, in particular when this technology is used to work on large parts with more than one 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, proper for tough soil.
The higher accuracy of the laser signal lays out the plan within a radius of 1300 meters, while the GPS system communicates the location of the leveller. Therefor, 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 soil permits to highlight the parts that has to be scraped, the loading areas, the section where to begin, and the best route that enables to do the greatest job 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 important accuracy and adaptability of the levellers made by Mara Laser secure their use in more than one fields:
- Laser levelling machines for agriculture:
Mara’s laser levellers, among the many plus secure a important increase of the arable parts. They permits a reduction in the amount of water used, they can provide more abundant harvest, a less use of chemicals, 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 gives a perfect precision to obtain ground floors with very reduced deflections (max 4 mm) and to annul cavities and gaps that would, afterwords, be filled with concrete. The decrease of work times and the possibility of obtaining a perfect slope for water to flow down, are other plus 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 amount of soil very quickly and with low power. In this way, shorter work times, lower costs and greater accuracy in creating the horizontal plan and tilt, are achieved.
- Laser levelling machine for sportsground:
this type of technology can be utilized very well in this area 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 laser levelling machines, it is also doable to work for the maintenance of green spaces. In this way, the right tilt and also a great aesthetic result are secured.
- Laser grader machines for roads:
in this area, important results are achieved thanks to the skills of the Mara’s laser graders to perform the same job as the motor grader, with less costs and more convenient times. In addition, there are important plus, for example specialized labor is no longer necessary, besides to the fact that the use of fine materials is reduced.
