The trolley has a chassis of base plate (1) with wheels (2), two vertical side frames (3,4) with side struts (6,7,8,9), and intermediate detachable shelves (5). Each side strut has a number of apertures, located above each other at variable distances, and rod-shaped supports (12) are fitted into the apertures of neighboring struts, to support the shelves. A locking element at the free end of a support is hooked into a side strut. When the shelves are fitted, the support are enclosed by eye-shaped holders fastened to the shelves.
