The invention discloses a super-lifting winch and a crane, which relate to the field of engineering machinery and are used for increasing the use safety of the super-lifting winch. The super-lifting winch comprises a winch motor, a sleeve, a super-lifting drum and a brake assembly, wherein the brake assembly is used for braking the super-lifting drum. According to the technical scheme, the brake assembly is additionally arranged, and the brake assembly is used for braking the super-lifting drum, so as to prevent the super-lifting drum from rotation under the action of load, so that the use safety of the super-lifting winch is increased. Obviously, according to the super-lifting winch provided by the technical scheme, the super-lifting drum can be prevented from rotation due to the load of a steel wire rope when an engine is shut down and the super-lifting winch is unlocked, so that the safety redundancy of a super-lifting system is increased, and the life loss of a hydraulic motor and material waste which are caused when the motor is continuously operated are reduced.
