Bending apparatus for flexible cables wound as a reel, said bending apparatus being intended to be operatively associated with an equipment piece for winding/unwinding flexible cables provided with a support structure intended to be abutted against a floor and with a winding drum rotatably mounted on the support structure; said bending apparatus comprising: - a support frame, intended to be placed below the winding drum of the equipment piece; - an operative arm, which is mounted on said support frame and comprises: - a constrained portion rotatably constrained to said support frame around a rotation axis; - a thrust portion spaced from said constrained portion and intended to act in abutment against a terminal portion of a flexible cable wound as a reel around the winding drum in order to plastically deform the terminal portion; - movement means, which are mounted on said support frame, are mechanically connected to said operative arm and are actuatable to move said operative arm between at least one lowered position, in which said thrust portion is intended to be spaced from the terminal portion of the flexible cable, and a lifted position, in which said thrust portion is adapted to abut against the terminal portion of the flexible cable in order to curve the terminal portion on the reel; said bending apparatus being characterized in that it comprises lifting means mechanically connected to said support frame and comprising at least one lifting device, which comprises: - at least one reaction member, adapted to interact with the floor; - at least one action member, which is engaged with the reaction member in a movable manner along a movement direction having at least one vertical component, is connected to said support frame, and is movable along said movement direction in order to position said support frame at multiple work heights. said bending apparatus comprising: - a support frame, intended to be placed below the winding drum of the equipment piece;
