    Abstract: An arrangement in a gate (10) wherein a cam track (23) is provided for lifting the gate on the pivot axis (12) thereof when the gate is being swung to opened position. An abutment (34) is provided in the cam track for a member (18) connected with the gate. The abutment is arranged to maintain the position in the cam track when the gate is being swung to opened position and is arranged for delayed yielding under the pressure exerted against the abutment by the gate (10) over the member when the gate is in opened position and is lifted by the cam track.
