With regular care and maintenance, connectors live longer – and safety re-mains ensured. This article discusses the calotte for the classic ball system lower coupling.
The calotte is the hemispherical “cup” in the trailer coupling that is placed onto the ball mounted on the tractor in the classic ball system lower coupling. Lack of up-keep, dirt and/or insufficient lubrication lead to excessive wear – but this can be prevented with regular care and maintenance. The ball and calotte will thank you with a longer service life.
