A nacelle-mountable lift system for mounting and dismounting a rotor blade of a wind turbine involves a jib crane mountable on the nacelle and a blade sheath. The blade sheath is connectable to the hook of the jib crane by lines attachable to the top end of the sheath. The holder is raiseable and lowerable by a winch mounted on the crane to raise and lower the sheath with the rotor blade retained therein when the rotor blade is disconnected from the hub or to raise and lower the sheath to retain the rotor blade in or release the rotor blade from the sheath when the rotor blade is connected to the hub.
