Скачать или смотреть Heavy Torque Wrench Worktool for Tower Crane Foundation Bolt Tightening

Torque wrench worktool bolt tightening is a critical technique in construction engineering. Torque wrench worktool bolt tightening ensures that tower cranes, steel frames, and heavy structures are properly secured to their foundations for safety and long-term stability.

Tools required include heavy-duty torque wrenches, torque bars, extension pipes, protective gloves, safety helmets, and harnesses. These tools allow workers to apply controlled torque to large bolts that secure massive structures.

Safety precautions must always be observed. Workers should wear helmets, gloves, and harnesses when working around tower cranes. The torque bar should be handled with both hands to prevent slips. Communication among team members is also important to avoid accidents when applying force together.

Important aspects include correct torque application, equal tension across all bolts, and proper alignment of steel structures. Over-tightening can cause bolt damage, while under-tightening risks instability and accidents.

Compared with old methods such as using short manual wrenches or improvised tools, modern torque wrench worktools provide better leverage, accuracy, and safety. Improvised tools often caused uneven bolt pressure, while torque-controlled tools ensure structural reliability.

Step-by-step process:
1. Inspect the crane base and foundation bolts.
2. Place the heavy torque wrench securely on the bolt head.
3. Attach an extension torque bar for greater leverage.
4. Workers position themselves safely around the bar.
5. Apply steady force to rotate and tighten the bolt.
6. Check torque level with calibrated measurement tools.
7. Repeat tightening process for all foundation bolts.
8. Inspect alignment of the crane base structure.
9. Perform a safety review before further crane assembly.
10. Record torque values for project documentation.

Countries that often use this worktool include China, the United States, Germany, the United Arab Emirates, and South Korea, where high-rise construction projects heavily rely on tower cranes and steel structures.
