A sucker for suctioning and lifting a sheet of plate glass has a sucker body defining a suction hole at a suction surface of the body. The sucker body carries a manual vacuum pump formed with a suction hole, a sensor for detecting the degree of vacuum and a sound generator. The sensor is provided in a suction channel connecting the suction hole at the suction surface of the sucker body with the suction hole in the vacuum pump. The sound generator is turned on when the sensor detects a predetermined degree of vacuum.
