FlexCow is used for animal comfort and increases work safety. Due to the spring mechanism, the cow immobilizer exerts a slight pressure on the cattle. Overloading of the animals due to incorrectly adjusted impact bars is avoided. Even falling down, which is the case when the impact bar is set too lightly, does not occur. FlexCow can be put on the cow without any effort and after unlocking the cow immobilizer automatically adapts to the cow.
