Abstract
The trolley has a lower platform which is provided with rollers and carries two fixed lateral grills and a movable grill between the fixed grills. At least one horizontal shelf is pivotably mounted on a first of the fixed grills and is pivotable between a withdrawn position against the first fixed grill and a horizontal position in which the shelf bears against a rod of the second fixed grill. A gate mounted on one of the fixed grills to be movable inwardly of the space defined by the three grills from a closed position to an open position prevents the shelf from being pivoted to its withdrawn position so long as the gate is in its closed position. A fixed gate is disposed above the lower platform. The distance between the gates and the shelf immediately above them is less than the height of the objects to be transported by the trolley.
