A self propelled carriage for a conveying and sorting machine has a frame (5) running along a monorail (2) on idle sheels (7), and provided with an independent motor (14) actuating spaced driving wheels (20) that engage the monorail (2) therebetween. Resilient basing means, such as a spring, link the motor (14) to the frame (5) to keep the adhesion between the driving wheels (20) and the monorail (2) constant. <IMAGE> |
