The trolley (1) has storage platforms i.e. grilles (14-16) for storing goods, and being provided with a telescopic retractable ladder moving between a retracted position and a deployed position. Actuatable immobilization units immobilize the trolley and operationally connected to the ladder such that displacement of the ladder from the retracted position to the deployed position causes actuation of the immobilization units. The immobilization units have a brake operated by a brake cable (4) for blocking rear wheels (3) or front wheels (5). |
