Mara - Laser Levelers

Catalogue

GPS grader for construction

Mara Laser is a business activity that for 30 years and more has been examining, producing and marketing laser and GPS controlled levellers, calling on buyers in about 30 states everywhere in the world.
Thanks to GPS and laser control technologies, it is feasible to achieve significant 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 advantages and high productivity in more than one situations: from the machine running speed regime, to a total trustworthiness and assurance of the result.

Mara’s technology

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 unrivaled performance, mostly when they are combined.

Laser technology

Laser technology is applied to the levellers in a way that continually synchronize the height of the blade.
The laser levelling machine, the laser beam transmitter and the laser beam receiver are parts of the laser control system for levelling.
The transmitter is located on a tripod that sees the natural gradient of the land and sends the signal to the receiver, which is instead put on the machine itself.
The laser beam, beacuse of its internal characteristics, permits very high accuracy even over long land portions. After obtaining the signal, a technologically perfectioned rotating pentaprism, put on these machines, returns an ideal program 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, 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 poor or it goes through interference.
On the laser levelling machine, moreover, there is a control system to remove external interference. It decreases wind sound, automatically reaches the signal and settles the power of the tractor.

GPS receiver 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, perceive the laser signal from the satellites: even in this situation the program is defined by the signal and reproduced on the land.
Lately, thanks to technological advancement and the use of dedicated software, an accuracy of ± 10 mm has been reached up, even though this technology offers minor accuracy than laser technology: GPS systems are subject to fluctuations beacuse 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 land portions 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 adds the precision of laser technology with the potential of GPS, perfect 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. Therefor, 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 land permits to highlight the land portions that has to be scraped, the loading areas, the point where to start, and the best route 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 significant accuracy and elasticity of the levellers manufactured by Mara Laser secure their use in more than one fields:

  • Laser levelling machines for agriculture:
    Mara’s laser levellers, among the different plus secure a important increase of the arable land portions. 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 hours, besides, 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 contained deflections (max 4 mm) and to remove cavities and gaps that would, later, be filled with concrete. The lowering of work hours and the possibility of obtaining an absolute perfect inclinatoin for water to flow down, are other plus that make these machines priceless and incomparable in this fields.
  • Laser levelling machines for earth-moving:
    the fine performance of the Mara levellers permits to move large quantity of soil very quickly and with low power. In this way, shorter work hours, lower costs and greater accuracy 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 area as it enables to level even existing areas, repairing slope without replacing the lawn.
  • Laser levelling machines for greenhouses:
    thanks to the accuracy, contained size and easy handling of Mara levellers, 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 ensured.
  • Laser grader machines for roads:
    in this area, important results are gained thanks to the skills 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 important plus, for example specialized labor is no longer needed, besides to the fact that the use of fine materials is reduced.
