ABSTRACT:
A press brake plate lifter has horizontally extending lift rails pivotally mounted to a supporting framework, for supporting and lifting sheet stock during press brake operations. The lift rail pivot axis is coextensive with the bending axis of the press brake die. The material support lift rails are horizontally adjustable to accommodate sheet stock of varying dimensions, while plate clamps mounted on the lift rails hold the sheet stock firmly during the bending operation.
