ABSTRACT:
A flexible bar handler that comprises a mobile carriage; a lift boom assembly rotatably attached to rotate around a vertical axis of the carriage to swing a distal end of the boom assembly back and forth and pivotally attached to pivot around a horizontal axis of the carriage to raise and lower the distal end of the boom assembly; 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 the distal end of the longitudinal boom assembly opposed to a counter weight attached at an opposite proximal end of the boom assembly, 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 that includes a mobile carriage; manipulating the lift bracket by (i) swinging an end of the boom assembly back and forth, (ii) raising or lowering an end of the boom assembly, (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 by the mobile carriage to position the bar for unloading into the stator slot; and unloading the bar into the slot.
