The offshore horizontal single-blade lifting appliance comprises a main cross beam, an angle adjusting mechanism, a blade root clamping mechanism and a blade tip clamping mechanism, the angle adjusting mechanism is arranged in the middle of the top face of the horizontal main cross beam, and the angle adjusting mechanism can adjust the position of a lifting point relative to the main cross beam; first pin shaft sleeves and second pin shaft sleeves are arranged at the two ends of the main cross beam correspondingly, and the multiple first pin shaft sleeves and the multiple second pin shaft sleeves are arranged at equal intervals in the axial direction of the main cross beam. A first pin shaft seat and a second pin shaft seat are arranged at the top of the blade root clamping mechanism; the first pin shaft seat and the second pin shaft seat are in pin shaft connection with a first pin shaft sleeve and a second pin shaft sleeve at one end; the mounting structure of the blade tip clamping mechanism is consistent with that of the blade root clamping mechanism; the blade root clamping mechanism and the blade tip clamping mechanism can clamp the blade. The invention further discloses a working method of the lifting appliance. Blades of different models can be rapidly clamped, and the posture of the blades can be adjusted in a multi-angle mode to meet the installation requirement.
