A milking system includes an assembly, a controller, and a milking cluster configured to attach to one or more teats of a livestock. The assembly includes a clevis, a piston, a pulley system, and a sensor. The clevis includes a first member, a second member, a base member, and a cylinder. The cylinder is coupled to the base member. The piston is positioned at least partially within the cylinder, and is configured to move within the cylinder. The pulley system of the assembly includes a cord configured to be coupled to the milking cluster. The assembly includes a sensor configured to generate a displacement signal in response to detecting that a portion of the clevis is within a predefined distance of the sensor.
