Zusammenfassung:	A force unit that may be readily employed to develop a pulling force for physically shaping, or molding, a work piece by bending, is disclosed. The force unit includes a power member which is physically moved by a hydraulically operated ram for the purpose of retracting a load chain or cable that is attached at one end to a stabilized work piece to be shaped and at an opposite end to the force unit. The ram is vertically mounted on an appropriate support. A fulcrum pulley is mounted at any vertical position along the length of the ram or a support post to which it may be attached. An anchor is employed to secure the force unit from movement in the direction of the work piece.
