Dairymaster ACR smart start ram spring The Dairymaster ACR Smart Start ram spring is a crucial mechanical component within the Automatic Cluster Removal (ACR) system’s Smart Start assembly. This spring provides the necessary tension and return force for the ram mechanism, ensuring smooth and precise operation during the initiation of milking. By controlling the ram’s movement, the spring helps regulate vacuum pressure to facilitate the automatic attachment and removal of milking clusters. Proper spring tension ensures timely cluster engagement and prevents premature release, contributing to animal comfort and milking efficiency. The spring is manufactured from durable materials designed to withstand repeated compression cycles and exposure to dairy farm conditions such as moisture and cleaning agents. Regular inspection and replacement of the ram spring are important to maintain consistent ACR Smart Start performance.
