ABSTRACT:
A rail-mounted conveyance wherein two undercarriages support a superstructure. One of the undercarriages is movable with reference to the superstructure about three axes including a substantially horizontal X-axis extending in the direction of travel of the conveyance, a substantially horizontal Y-axis which extends transversely of the direction of travel of the conveyance, and a substantially vertical Z-axis which is normal to the other two axes. Movements about the X-axis are made possible by providing the one undercarriage with a transverse axle which defines the Y-axis and carries a block having a convex top surface sloping from the center toward both sides of the one undercarriage, and by providing the superstructure with a platform having a flat underside which abuts against and can roll along the convex surface. The line of contact between the block and the platform defines the first axis. The platform has two downwardly extending pyramidal projections which are partially or fully received in complementary sockets provided in the convex surface of the block at the opposite sides of the center of the one undercarriage, as considered in the direction of the Y-axis. These projections prevent other but rolling movements of the underside of the platform with reference to the convex surface and/or vice versa.
