A dolly for facilitating the moving of heavy objects. The dolly includes a chassis (1-4) for supporting the object (24) and having roller means (13-20) enabling the chassis to be rolled on the ground or the floor (23). The top side of the chassis has plane abutment surfaces (1d, 2d, 3d) which are located above the roller means (13-20) and permitting the dolly to be turned upside down and to rest with the abutment surfaces against the ground (23). The chassis has a through hole (6), the size of which is adjustable, and in which the object may rest when the dolly is placed with its roller means on the ground, and, as well, when the dolly is turned upside down and rests with the abutment surfaces against the ground, the dolly in its upside down position thereby being capable of serving as a chock for the object. The hole (6) is open also towards one side to permit the dolly, in its upside down position, to be slid into place under the object (24), also if this rests on the ground. |
