Automatic opening

This pig gate opens doors automatically. Whenever a pig goes into or out of the gate, a compression spring closes or opens the door. In the past, the extreme soiling and ammoniac load in pigstys led to the bearings becoming clogged and corroding. This made the compression springs crooked and often led to breaks.With the aid of lubricant-free and dirt-resistant iglidur® plain bearings, the stainless steel spring is now only under load whenstraight and thus lasts correspondingly longer.
