Abstract

Device for the movements of a carriage along a crane arm, the arm of which comprises at least two trunks (1, 2; 17, 18) telescopically displaceable relative to one another, characterized in that a first trunk (1; 17) of crane arm has a pair of guides or tracks (3; 19) parallel to each other, and because a second trunk (2; 18) of crane arm includes in turn a pair of parallel guides or tracks (4; 20) each other, the two pairs of guides or tracks (3,4; 19, 20) belonging to the two trunks mentioned (1, 2; 17, 18) of the crane arm being placed in such a way that they do not interfere with each other during the movement of one trunk with respect to the other, said carriage (6; 21) being provided with a first group of rollers (7; 22) suitable to support and slide on the two guides (3; 19) or tracks belonging to the first trunk. (1; 17) and a second group of wheels (18; 23) suitable for supporting and moving on the two guides (4; 20) or tracks belonging to the second trunk (2; 18), the placement of the two mentioned groups of wheels (7, 8, 22, 23) on the carriage (6; 21) being such, with respect to the placement of the two pairs of guides or tracks (3, 4;, 20) on the two trunks (1, 2, 17, 18) of the crane arm, that when one group of wheels leaves the two corresponding guides or tracks, the other group of wheels rests on the corresponding guides or tracks, and vice versa.
