To ensure crane safety, adhere to these guidelines:

1. Qualified Operators: Cranes must be operated only by trained and authorized personnel [1]. Operators should be able to communicate effectively and understand safety protocols [1]. They should also meet specific physical requirements, including vision, hearing, and physical capabilities [1].
2. Regular Inspections: Conduct frequent (daily to monthly) and periodic (1 to 12-month intervals) inspections 1, 4. Inspect for defects in operating mechanisms, deterioration, leakage, and deformations or cracks in hooks 1, 6. Keep written, dated, and signed reports of these inspections 6, 11.
3. Rope Inspections: Inspect ropes monthly, looking for deterioration, broken wires, corrosion, and worn end connections 2, 7. Maintain records of rope conditions 2, 7.
4. Load Management: Do not exceed the crane's rated load, except for testing purposes 14, 18. Ensure the load is well-secured and balanced before lifting 14, 18. Avoid carrying loads over people [2].
5. Operational Testing: Test new and altered cranes for hoisting and lowering, trolley travel, bridge travel, and limit switches [3].
6. Maintenance and Repairs: Correct any unsafe conditions before resuming crane operation [4]. Adjustments and repairs should be done by designated personnel [4]. Reinstall all guards and reactivate safety devices after maintenance 2, 7.
7. Warning Devices: Cranes with powered traveling mechanisms should have a gong or other effective warning signal [5].
8. Clearance and Safety: Maintain minimum clearances between the crane and obstructions [6]. Avoid bumping into runway stops or other cranes [7].
9. Environmental Conditions: If the crane is outdoors, secure it in a safe position to prevent movement in severe winds [7]. Stop crane operation when wind velocity or temperature exceeds the manufacturer's recommended limits [8].
10. Tower Cranes: Tower cranes require non-destructive testing of structural and rigging components under the direction of a professional engineer [8]. If tower cranes are close enough that their operation radiuses overlap, ensure that operators have visual or auditory means of communicating with each other [8].

By following these guidelines, you can significantly enhance crane safety and reduce the risk of accidents.
