Mechanical selector for trolleys, of the type whose wheels are triple in a common support, essentially characterized in that it comprises on each side plates with two lower notches and hinged at its front end to the sections portamanillar, whose plates are rigidly related to each other by a crossbar of control fixed to the plates above its axis of articulation and having centrally a drive pedal, whose cross-piece plays in half-elastic fasteners to adopt two stable upper and lower extreme situations, and an intermediate situation, to achieve three positions of use: two locking the wheel supports, one for dragging on one wheel on each side and another for dragging on two wheels on each side, and whose third position leaves the wheel supports free so that they can turn when bumping into an obstacle and save it.
