Abstract
A mechanism for lifting a wheel set, such as a railroad wheel set, is constructed for cooperation especially with wheel truing machines for lifting a wheel set into a machining position or out of the machining position. In order to facilitate the chip removal, the lifting mechanism is tiltably mounted in a chip removal pit. In its uplifting working position a cover of the lifting mechanism substantially closes the chip pit except for the wheel carriers. In the recessed position of the lifting mechanism the cover tilts along with the lifting mechanism thereby guiding any chips accumulated on the cover onto a chip removing conveyor in the pit. For this purpose the lifting mechanism has a movable frame hinged to a stationary frame so that the hinging axis extends outside of a lifting plane passing through the rotational axis of the wheel set.
