Description

Technical Field

[0001] This utility model relates to an oil-proof device for crane hooks, and belongs to the technical field of crane hooks. Background Technology

[0002] Currently, both the casting and rolling hoisting of goods and finished coils are operated using overhead cranes. The wire ropes used for crane lifting require lubrication with grease. As the ambient temperature rises, the lubricating grease falls off the wire ropes. Since the lubricating grease is a heavy oil, it falls onto the finished casting and rolling coils during hoisting, seriously affecting product quality. There is no oil-proof and oil-catching device at the crane hook, causing the lubricating grease to fall onto the finished coils, affecting product quality and bringing certain adverse effects to actual use. Therefore, improvements are needed. Utility Model Content
