Crowd gate for milking parlor holding areas

摘要

A carriage mounted, horizontally pivoted, crowd gate for a milking parlor holding area in which cattle are admitted through an entry end of the holding area which is opposite the exit to the milking parlor. An overhead cable which is connected to the top of the gate for moving the gate from end to end of the holding area carries a lifting cable which is secured to the drive cable a short distance from the gate toward the entry end, and which is secured to the bottom of the gate. By blocking the carriage while continuing to operate the drive cable toward the entry end the lifting cable is pulled to swing the gate up on its pivots, after which a lug on the cable strikes a limit switch to stop the gate drive. Opposite movement of the drive cable slacks the lifting cable so the gate returns to vertical position.
