Due to the improper using, the existing device used in anti-releasing for crane hock can often lead to deformation and even fall away from the crane hock. It is easy to create the safety accident. This paper presents an applied device used in anti-releasing for crane hock. It is very convenient to loading and unloading the rigging, which adopts the gravity lever principle. And the structure is stronger than the existing device. It is worth spreading.
