Mara Laser is a business company that for over 30 years has been analyzing, producing and trading laser and GPS controlled laser levelling machines, calling on buyers in about 30 states everywhere in the world.
Thanks to GPS and laser control technologies, we can get to outstanding results in many areas 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 productivity in various situations: from the machine running speed regime, to a total trustworthiness and certainty of the result.
The technology used by Mara is what makes it unique, and the results acquired all over the world witness this. Laser and GPS receiver technologies provide an unrivaled 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 parts of the laser control system for levelling.
The transmitter is placed on a tripod that sees the natural gradient of the soil and communicates the signal to the receiver, which is instead mounted on the machine itself.
The laser beam, for its own characteristics, permits very high preciseness even over long sections of land. After picking up the signal, a technologically perfectioned rotating pentaprism, mounted on these machines, returns an ideal pianification for the leveller to follow while running.
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 move on any kind of soil and receive the 360° signal, even if it could be poor or experiences interference.
On the laser leveller, besides, there is a control system to remove external interference. It cuts wind rumble, automatically captures the signal and settles the power of the tractor.
GPS receiver technology
GPS technology, however, is used to set the position of the laser leveller and the height of the blade.
The levellers, that adopt this technology, get the laser signal from the satellites: even in this situation the pianification is illustrated 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 obtained, 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, in particular when this technology is used to work on large parts with various inclinations, such as agricultural soil 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, perfect 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. Therefor, 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 permits to highlight the parts that has to be scraped, the loading areas, the starting point, and the best way that enables to make the best work 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 outstanding preciseness and elasticity of the levellers made by Mara Laser secure their use in various fields:
- Laser levelling machines for agriculture:
Mara’s laser levellers, among the many plus secure 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, besides, 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 reduced deflections (max 4 mm) and to remove cavities and gaps that would, later, be filled with concrete. The decrease of work times and the possibility of obtaining an absolute perfect inclinatoin for water to flow down, are other plus that make these machines priceless and priceless in this fields.
- Laser levelling machines for earth-moving:
the fine 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 preciseness in creating the horizontal plan and gradient, are gained.
- 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 slope without replacing the lawn.
- Laser levelling machines for greenhouses:
thanks to the preciseness, 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 gradient and also a great aesthetic result are assured.
- Laser grader machines for roads:
in this field, important results are gained thanks to the capability of the Mara’s laser graders to provide the same job as the motor grader, with minor costs and more convenient times. In addition, there are key plus, for example specialized labor is no longer needed, on top to the fact that the use of fine materials is reduced.
