Sample collector with a trolley that moves lengthwise onto rails of up to 24 meters of length at approximately 4,5 meters from the ground, with up to 160-degree rotation, an arm with a length of 2,8 meters and a collector probe of proven efficiency, performs all of its movements (longitudinal movement, rotation and setting) through electric motors, taking all hydraulic components out of these functions. The rails, attached along the pillars placed every 6 meters, are intended to not hinder the internal movement of the unit in which the collector is installed, whereas when operating more than 4 meers above the ground, the equipment can safely operate at faster speed conditions.
