摘要

Birth aid apparatus for large cattle with a winding drum driven by a crank where the winding drum is split into three separate part drums which can be separately connected and disconnected for the exertion of a separate or simultaneous pull og at least three cables. Specifically the part drums have key-slide clutches which can be engaged and disengaged by moving the drums on the winch shaft. The part drums can be arrested in their various positionings. The calf is normally born with the head stretched over the two forelegs. The three cables and associated drums enable the tugging force to be controlled.
