The present invention discloses a super large tonnage detachable hook. The hook comprises: a hook rod, a hook shaft, a hook body, a spherical roller bearing, and a thrust spherical roller bearing. The hook also contains a connection component which connects the hook rod to the hook body. The split-type self-locking sleeve is integrally connected to the hook rod by means of the hook hoop holder. This connection form adopts the meshing of the sleeve and the toothed sleeve of the hook rod to transmit the load, and the bearing capacity is greatly improved compared with the traditional screw connection. The split-type self-locking sleeve can hold the toothed sleeve on the hook rod from both sides respectively. This new type of hook adopts a special structure force transmission system, so that the hook can withstand the downward and upward bi-directional load, which solves the problem that the traditional hook is prone to damage once it hits the ground. The main load-bearing components of the hook assembly are forged of high-strength alloy steel 30CrNiMo8 as a whole. The hook achieves a good overall load-enduring performance and longer fatigue life. The lifting hook provided by the present invention has a single hook with an extremely large lifting weight of 5,000 tons and above; and creatively adopts a new structure form, a force transmission system, a material, and a manufacturing form. The hook has many advantages, such as: light weight, large bearing capacity, reasonable force transmission path, good waterproof performance, long service life and other advantages. It can greatly improve the working capacity and efficiency of floating cranes.
