1. The role and importance of rail bolts
The rail hook bolt is a steel plate that fixes the rail and the ground, and plays a fixing role when the crane is in operation. The crane rail hook bolt is a bolt that fixes these steel plates to the ground to prevent the rail clamp from moving or loosening during the operation of the crane. Therefore, the quality and grade standards of rail hook bolts are crucial to ensure the safe operation of the crane.

2. Grade standards
The grade standards of rail hook bolts are generally 8.8 or 10.9. Among them, 8.8-grade bolts refer to bolts made of carbon steel with a tensile strength of 800N/mm², which are usually used in low-strength occasions; while 10.9-grade bolts are made of alloy steel with a tensile strength of 1000N/mm², which are usually used in high-strength occasions. The specific choice of which grade of bolts needs to be determined according to the use environment and safety requirements.
3. Quality standards
Rail hook bolt quality standards include specifications, surface conditions, tensile strength and torsional strength, etc. These standards will affect the working efficiency and safety of the crane. Therefore, when selecting and purchasing rail bolts, pay attention to these quality standards and ensure that the relevant standard requirements are met.
