Zusammenfassung:A flexible bar handler comprises a mobile carriage; a lift boom comprising a longitudinal shaft rotatably attached to rotate around a vertical axis of the carriage to swing an end of the shaft back and forth and pivotally attached to pivot around a horizontal axis of the carriage to raise and lower the end of the shaft; and a lift bracket comprising an elongated rail with receptor-shaped cross section to lengthwise accommodate a bar, the lift bracket being attached at a point on its length at a terminal end of the longitudinal shaft opposed to a counter weight attached at an opposite terminal end of the shaft, wherein the lift bracket is pivotally attached to a horizontal pin at the point to permit the lift bracket to tilt to one side or the other so as to raise and lower the lift bracket ends. A method of handling a stator bar; comprises loading the bar into a lift bracket comprising an elongated rail with receptor-shaped cross section, wherein the lift bracket is part of a flexible bar handler; transporting the bar to an unloading area in proximity to a stator slot of a stator core; manipulating the lift bracket by (i) swinging an end of the shaft back and forth, (ii) raising or lowering an end of the shaft, (iii) tilting the lift bracket to tilt the bracket to one side or the other so as to raise and lower the lift bracket ends or (iv) moving the bar forward or backward to position the bar for unloading into the stator slot; and unloading the bar into the slot.
