A carriage comprising a frame (14) that carries two in the running direction of the carriage separated wheel sets (2, 3), a superstructure (11, 12) for an upper load carrier (10), and a lower load carrier (5) which is arranged displaceable in the running direction of the carriage to and from a position substantially under the upper load carrier (10). The frame (14) comprises a connection device (4) that has two relative to each other in the running direction displaceable parts (41, 42) of which one part (41) carries the superstructure (12) and a first (2) of the wheel sets (2, 3) and of which the second part (42) carries the other (3) of the wheel sets (2, 3). The lower load carrier (5) follows the second wheel set (3). A releasable blocking device (43, 44) is arranged to releasably block the first and second part of the connection device (4) to each other. |
