GPS leveller for construction

Mara Laser is a business company that for 30 years and more has been analyzing, making and trading laser and GPS controlled laser levellers, calling on clients in about 30 states everywhere in the world.
Thanks to GPS and laser control technologies, we can get to significant results in different sectors of utility: from agricoltural ground to sport facilities, from building constructions to road excavations, from landscaping to ground scraping.
Mara’s levellers ensure a series of advantages and high productivity in more than one situations: from the machine running velocity, to a total trustworthiness and guarantee of the final success.

Mara’s technology

The technology used by Mara is what makes it unique, and the results obtained all over the world are proof of this. Laser and GPS system technologies provide an unrivaled performance, mostly when they are used together.

Laser technology

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 positioned on a tripod that sees the natural tilt of the soil and communicates the signal to the receiver, which is instead positioned on the machine itself.
The laser beam, beacuse of its internal characteristics, enables very high preciseness even over long sections of land. After picking up the signal, a technologically perfectioned rotating pentaprism, positioned on these machines, returns an ideal planning for the leveller to follow while running.
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 move on any type fo ground and receive the 360° signal, even if it could be poor or it goes through interference.
On the laser levelling machine, moreover, there is a control system to annul external interference. It lowers wind sound, automatically captures the signal and settles the power of the tractor.

GPS system technology

GPS technology, after all, is used to settle the position of the laser levelling machine and the height of the blade.
The levellers, that adopt this technology, get the laser signal from the satellites: even in this situation the planning is represented by the signal and reproduced on the soil.
Nowadays, thanks to technological progress and the use of dedicated software, an accuracy of ± 10 mm has been reached up, even though this technology offers less accuracy than laser technology: GPS systems are subject to fluctuations beacuse of the periodic change of constellation of the satellites.
In any case, the less preciseness 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, the right one for tough soil.
The higher preciseness of the laser signal shows the plan within a radius of 1300 meters, while the GPS system communicates the precise spot of the leveller. Thus, the Mara system can settle the height of the tractor leveller and the precise spot of the blade itself.
The creation of the 3D map of the soil enables to highlight the parts that has to be scraped, the loading areas, the section where to begin, and the best route that allows to do the greatest job possible, with both the tractor and the leveller in the right position.
Thus, the operator will have immediate instructions through the constant updating of the data by the system.

Fields of application

The significant preciseness 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 different conveniences assure a important increase of the arable parts. 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, furthermore, 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 reduced deflections (max 4 mm) and to annul cavities and gaps that would, later, be filled with concrete. The lowering of work times and the possibility of obtaining an absolute perfect inclinatoin for water to flow down, are other conveniences that make these machines worthy and incomparable 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 tilt, are gained.
  • Laser levelling machine for sportsground:
    this type of technology can be used very well in this area as it makes possible to level even existing sectors, repairing slope without replacing the lawn.
  • Laser levelling machines for greenhouses:
    thanks to the preciseness, reduced size and easy handling of Mara laser levellers, it is also feasible to work for the maintenance of green spaces. In this way, the right tilt and also a fabulous aesthetic result are assured.
  • Laser grader machines for roads:
    in this area, important results are gained thanks to the capacity 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 conveniences, for example specialized labor is no longer needed, besides to the fact that the use of fine materials is reduced.
