The invention provides a main and auxiliary hook lifting type eccentric lifting appliance and a lifting method, and relates to the technical field of ship lifting, the main and auxiliary hook lifting type eccentric lifting appliance comprises a supporting beam, a main lifting hook and an auxiliary lifting hook, lifting shaft assemblies are arranged on the two sides of the supporting beam, and upper connecting locks are connected to the lifting shaft assemblies; the upper connecting lock comprises a first joint-free rope loop rigging, a second joint-free rope loop rigging and a third joint-free rope loop rigging; the first joint-free rope loop rigging, the second joint-free rope loop rigging and the main lifting hook are connected, the third joint-free rope loop rigging and the auxiliary lifting hook are connected, under the condition that the load of the main lifting hook is limited, the load and the distance of lifting points can be flexibly adjusted according to the gravity center position of a lifted object through matched use of the auxiliary lifting hook and the main lifting hook, and the lifting efficiency is improved. The lifting bearing of the main lifting hook and the auxiliary lifting hook is reasonably distributed to adapt to different lifting environments, so that the lifting appliance is lighter, the application range of the lifting appliance is widened, and the lifting requirements of various complex ships are met.
