Mara - Laser Levelers

Catalogue

Used laser leveller blade for agricultural soil

Mara Laser is a business company that for over 30 years has been examining, producing and marketing laser and GPS controlled laser levellers, calling on buyers in about 30 states all over the world.
Thanks to GPS and laser control technologies, we can reach considerable results in different areas of utility: from agricultural soil to sport facilities, from building constructions to road excavations, from landscaping to ground scraping.
Mara’s levellers ensure a series of returns and high productivity in more than one situations: from the machine operating speed regime, to a total affidability and assurance of the result.

Mara’s technology

The technology used by Mara is what makes it unique, and the results obtained all over the world testify this. Laser and GPS receiver technologies provide an unrivaled performance, in particular when they are combined.

Laser technology

Laser technology is applied to the levellers in a way that without stopping synchronize the height of the blade.
The leveller, the laser beam transmitter and the laser beam receiver are parts of the laser control system for levelling.
The transmitter is put on a tripod that observes the natural inclination of the land and sends the signal to the receiver, which is instead positioned on the machine itself.
The laser beam, as it is one of its internal characteristics, enables very high accuracy even over long land portions. After obtaining the signal, a technologically perfectioned rotating pentaprism, positioned on these machines, returns 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 kind of ground and receive the 360° signal, though it could be low or it is subjected to interference.
On the leveller, also, there is a control system to annul external interference. It decreases wind rumble, automatically intercepts the signal and sets the power of the tractor.

GPS receiver technology

GPS technology, after all, is used to settle the position of the leveller and the height of the blade.
The levellers, that adopt this technology, perceive 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 poorer 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 poorer accuracy is compensated by the wide elasticity 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 produced and manufactured an integrated system that connects the precision of laser technology with the potential of GPS, proper for tough land.
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 settle 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 parts that has to be scraped, the loading areas, the point where to start, 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 instant instructions through the constant updating of the data by the system.

Fields of application

The considerable accuracy and elasticity of the levellers manufactured by Mara Laser ensure their use in more than one areas:

  • Laser levelling machines for agriculture:
    Mara’s laser levellers, among the different benefits ensure a important increase of the arable parts. They enable 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 provides 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 lowering of work times and the possibility of obtaining a perfect inclinatoin for water to flow down, are other benefits that make these machines incomparable and priceless in this areas.
  • Laser levelling machines for earth-moving:
    the first-rate performance of the Mara levellers enables to move large quantity 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 inclination, 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 areas, repairing soil depressions without replacing the lawn.
  • Laser levelling machines for greenhouses:
    thanks to the accuracy, 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 inclination and also a fabulous aesthetic result are assured.
  • 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 poorer costs and more convenient times. In addition, there are important benefits, for example specialized labor is no longer necessary, besides to the fact that the use of fine materials is reduced.
