Abstract

See full text

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 via the hook hoop holder. Meshing of the sleeve with the toothed sleeve of the hook rod is adopted to transmit the load, and the bearing capacity is greatly improved compared with the traditional screw connection. The hook of the present invention 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 hook is forged with 30CrNiMo8, which can lift an extremely large weight of more than 5,000 tons.
