The trolley is designed to be pushed by hand and several trolleys may be pushed into each other forming a train of trolleys. It has wheels pivoted about a vertical axis, and the rear wheels may be locked in a position, for forward movement. The locking is released, when a second trolley is pushed into the first, and engage automatically, when it is removed. The locking may also be released by a grip (2). A lever (3) below the grip may be moved by hand towards it. The lever movement is transmitted via rod (5) onto the control elements (7) for the locking.
