Lifting is a high-risk operation, so safety operating regulations must be strictly followed to ensure the safety of personnel and property. The following are the key points for safe operation of lifting: 1. Safe standing positionDuring the hoisting operation, it is very dangerous to stand under the boom, under the hoisted object, in the front … Read more

The crane hook plays the role of connecting cargo and is subjected to great force during use. Coupled with the friction of the wire rope, it may break and cause an accident if it is not properly inspected. Therefore, the requirements for such products during use are very high, and no carelessness can be taken … Read more

The length of quenching time is one of the important factors affecting the mechanical properties and dynamic load strength of crane wheel forgings. In order to make the wheel have high mechanical properties, the quenching depth must be very large when surface quenching is performed. At the same time, considering that a large amount of … Read more
