The invention discloses a crane fly jib support and a crane, the crane fly jib support comprises a rear support, the rear support comprises a support body, a mounting assembly, a pulley yoke, two pulleys, a recovery wire coil and a motor; the installation assembly is connected with the support body and used for being connected with a crane main arm. The pulley yoke is rotationally connected with the bracket body; the two pulleys are oppositely arranged on the pulley yoke and are rotationally connected with the pulley yoke; the recovery wire coil is connected with an output shaft of the motor, a wire rope is wound on the outer wall of the recovery wire coil, one end of the wire rope is used for being connected with a crane fly jib, and after the motor is started, the wire rope pulls the crane fly jib, so that the crane fly jib receives obliquely upward pulling force and gets close to a crane main jib. The recovery convenience and the suspension stability of the crane fly jib can be improved.
