ABSTRACT:
Yoke particularly for lifting motor-cars by applying lifting forks under an axle or other suitable lifting point of the car and thereafter pushing the yoke upwards. The yoke has two end portions each designed as an open box formed of two longitudinal vertical side plates and at least one vertical end plate. A sleeve for journaling a shaft bar extends through each end portion and has an outer diameter which is somewhat smaller than the distance between the vertical side plates, so that the sleeve may be longitudinally displaced within the open box between two end positions and may be securably adjusted in different positions between the two end positions.
