a log charger system employs scan data to precisely orient a log rotationally prior to presenting the log to a carriage for sawing operations or the like . once the log is rotated to the desired orientation , a v - shaped member picks the log up from underneath and moves it to the carriage . the v - shaped member has a lower - able or minimize - able side profile to enable it to retract away from the log , leaving it clamped to the carriage for further operations .
