A carriage for suspending a load such as a compartment of a vehicle or the like, is basically comprised of a pin, rod or bar from which the load is centrally suspended and which by and in itself is suspended by two wheel carriers, each supporting a wheel for running on opposite flanges of a rail; each wheel carrier has a clamping bore intersecting the bore receiving the load carrying rod and a tension pin-with-wedge is inserted in an intersecting bore for clampingly engaging the load bearing rod upon tightening of a nut on an external thread of the respective tension pin; loosening of the nuts releases a contour fitting engagement and permits the wheel carrier to be adjusted into any desired position on the load carrying rod; the wedges may be constructed as cutting edges for cutting into the load carrying rod upon tightening.
