Disclosed is a foldable chassis (100, 200, 300) of manually driven carrier vehicles capable of self-locking in unfolded position. The chassis includes a frame (110) having a reference plane, an actuator (140, 240) attached pivotally to said frame, a first mechanism (130, 230) comprising said actuator and a platform (131, 231) attached pivotally to said frame, and a second mechanism (150) comprising said actuator and two arms (160), each attached to said frame pivotally around a first axis (117) and configured for attaching a wheel arrangement (170, 371) rotatable around a second axis (162). Said first and second mechanisms configured to move independently of each other between at least a first position, in which said platform generally perpendicular to said frame and said wheel arrangements generally perpendicular to said reference plane, and a second position, in which said platform adjacent to said frame and said wheel arrangements adjacent and parallel to said reference plane.
