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 nations everywhere in the world.
Thanks to GPS and laser control technologies, we can get to important results in many sectors of use: 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 more than one situations: from the machine operating speed regime, to a total affidability and certainty of the result.
The technology used by Mara is what makes it unbeatable, and the results acquired all over the world witness this. Laser and GPS receiver technologies give 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 the elements of the laser control system for levelling.
The transmitter is put on a tripod that observes the natural tilt of the land 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 picking up the signal, a technologically perfectioned rotating pentaprism, put on these machines, gives back an ideal pianification 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, made by Mara Laser, guarantee the levellers will be able to work on any kind of ground and receive the 360° signal, even though it could be poor or experiences interference.
On the laser levelling machine, besides, there is a control system to annul external interference. It cuts wind rumble, automatically captures the signal and regulates the power of the tractor.
GPS receiver technology
GPS technology, however, is used to regulate 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 pianification is illustrated 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 obtained, even though this technology offers minor 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 minor accuracy is compensated by the wide elasticity of use, mostly when this technology is used to work on large parts with more than one inclinations, such as agricoltural ground and building constructions.
Integrated laser + GPS system
Mara Laser has created and made an integrated system that connects the precision of laser technology with the potential of GPS, proper 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. Hence, the Mara system can regulate 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 allows to do the greatest job possible, with both the tractor and the leveller in the right position.
Hence, the operator will have immediate instructions through the constant updating of the data by the system.
Fields of application
The important accuracy and elasticity of the levellers made by Mara Laser assure their use in more than one areas:
- Laser levelling machines for agriculture:
Mara’s laser levellers, among the many conveniences assure a key increase of the arable parts. They enable 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, later, be filled with concrete. The decrease of work times and the possibility of obtaining a perfect inclinatoin for water to flow down, are other conveniences that make these machines incomparable and priceless in this areas.
- Laser levelling machines for earth-moving:
the first-rate 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 reached.
- Laser levelling machine for sportsground:
this type of technology can be used 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 levellers, it is also feasible to work for the maintenance of green spaces. In this way, the right tilt and also a great aesthetic result are ensured.
- Laser grader machines for roads:
in this area, 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 conveniences, for example specialized labor is no longer needed, on top to the fact that the use of fine materials is reduced.
