System comprising an automatic crane and a subsurface system for collection of refuse the system comprising various independent modules according to the type of refuse to be collected, the system further consisting of, in the subsurface area, an underground bunker and a container for collection of the refuse by means of the automatic crane and a cover, which opens up to 90 degrees supporting a paving, a post with a deposit bin located at a height of around 90 cm located on the cover, wherein the system includes: - means to open and close the cover; - a collection truck with the automatic crane; and - means to automatically hitch the automatic crane of the collection truck to the container; wherein the system is characterized by - a safety device comprising a moving element which remains stowed against the wall of the bunker when the container is inside the bunker and tips into the horizontal position when the container is collected, covering the bunker opening; - means to open and close the deposit bin for use only by specified users; - means to measure the volume of refuse in the container; - means to measure the weight of a container; - means to measure the weight of refuse deposited in the deposit bin accessible only to specified users; - the means for automatic hitching of the automatic crane of the collection truck to a container emptied from below, used for automatic lifting and transfer of the container to an emptying point by means of an automatic system of proximity sensors, are such that said container is completely open on the upper side and is equipped on each side with a single set of arms, which at their upper extremity are configured to be connected to the coupling system located at the top of the crane, and at the lower extremity are connected to a base of the container, which base is articulated with hinges to the body of the container; said set of arms comprising a movable arm located within a fixed arm coupled to the body of the container and both arms having at the top a groove (27 and 27') for coupling; said coupling system connected to arms of the crane having a horizontal arm able to rotate 360 degrees and two other vertical arms, which move vertically by means of fluid-operated cylinders of the system; each of the two vertical arms of the coupling system comprising an outer element and an inner element, which in turn both possess at each extremity a grip (30 and 30') for coupling; coupling being effected by means of hitching of the lower element to the grooves on the movable arms of the container and hitching of the outer element to the grooves of the fixed arm of the container, thus enabling rigid and automatic lifting of the container to the emptying point; by vertically moving the inner element of the vertical arms of the coupling system by means of the fluid-operated cylinders, and by pushing or pulling of the movable arm on the container it is thus possible to open and close the base of the container in order to empty it of refuse. - means to open and close the cover;
