In order to implement the technological restructuring of the milk production process at large scale it is necessary to ensure a constant and efficient operation of the milking and dairy equipment. This article highlights some of the technological challenges that are common in the operation of milking systems. It describes the main parameters of teat cup liners, which are both important forme asurements and affect significantly the milking process. It has been found that the development of new reasonable and effective technological solutions regarding dairy cattle exploitation along with improving the parameters and operating regimes of the means of implementation in production processes provide the background for identifying them aximum productive capacity of animals as well as for improving the efficiency of the staff. The method and the device for determining the teat cup liner tension in the milking machines based on the use of a dial indicator to control the liner tension have been developed. The implementation of presented developments into production will ensure the prompt receipt of reliable information regarding the liners’ tension which will enable timely detection of negative factors, and namely the lower tension.
