  • Strengthen workers’ awareness of safety protocols.
  • Promote adherence to established regulations to reduce unsafe behaviors.
• Implementation:
  • Conduct regular safety training sessions.
  • Integrate safety drills into routine operations to reinforce best practices.

2. Avoiding Collisions Between Multiple Cranes

• Key Measures:
  • Develop and implement strategies to prevent crane collisions in worksites with multiple units.
  • Maintain a minimum installation distance of at least 2 meters between adjacent tower craneS.
• Advanced Approaches:
  • Use anti-collision systems equipped with sensors and alarms.
  • Schedule and coordinate crane operations to avoid overlapping zones.

3. Professional Installation and Top Climbing Operations

• Requirement:
  • Entrust top-climbing (jacking) and anchoring tasks to certified and qualified installation companies.
• Benefits:
  • Ensure compliance with industry standards.
  • Minimize risks associated with improper assembly or modification.

4. Foundation Construction Standards

• Guidelines:
  • Ensure the foundation meets the safety requirements of the entire tower crane.
  • Implement proper drainage measures to prevent water accumulation.
• Zusätzliche Überlegungen:
  • Conduct soil tests to evaluate load-bearing capacity.
  • Use reinforced concrete bases for enhanced stability.

5. Embedded Bolt Quality and Installation

• Standards:
  • Only use embedded bolts with product quality certificates.
  • Ensure embedding and connections adhere to the manufacturer’s specifications.

6. Vertical Alignment of the Tower Mast

• Tolerance Level:
  • The vertical alignment deviation of the tower mast from the base plane should not exceed 4/10,000.
• Tools and Techniques:
  • Use laser levels or plumb lines for precise alignment.

7. Integrity of Metal Structures

• Inspection Checklist:
  • Metal structures must be free of cracks, weld defects, and permanent deformations.
• Preventive Measures:
  • Conduct periodic ultrasonic or magnetic particle inspections to detect hidden flaws.

8. Proper Use of Connection Pins

• Best Practices:
  • Ensure that connection pins are correctly installed and securely fastened.
  • Implement reliable axial locking mechanisms to prevent pin displacement during operation.

9. Compliance of Brake Systems

• Technical Requirements:
  • All braking devices must meet the specified technical standards.
• Maintenance:
  • Regularly inspect and test braking systems for functionality and wear.

10. Safe Use of Hooks

• Prohibitions and Standards:
  • Welding of hooks is strictly prohibited.
  • Hook surfaces must be free of visible defects such as cracks, fractures, or dents.
• Safety Devices:
  • Hooks must be equipped with anti-detachment devices to prevent wire ropes from slipping off.
