Alternate traction Vink calving aid has all the properties of the standard model with the addition of a ratchet that allows for alternate leg pull with each stroke of the handle. This can be very useful with a difficult calving as the 'wriggling action' eases delivery. This model is only supplied with an alternative traction ratchet which is more powerful than the standard model. it is designed to hang on to the cow whether she is standing or goes down in the middle of the job. The permanently attached holding frame fits over the cow’s hip bones, acting as a steady and fixed base from which the Calving Jack tilts and pulls regardless of whether the cow stands, sits or stretches out. This calving jack was developed after extensive institutional research into the forces required for the safest and most humane birthing assistance. It is made entirely from stainless steel. The standard pole is 1.8m long (30mm section).
