Critical Pre-Lift Checks in Adverse Weather

For Crane Operators

When operating crane trucks in adverse weather conditions, operators should always carry out a good safety inspection before every lift. This is to ensure that the equipment as well as the environment is ready for safe and effective operation. The following is a checklist for crane operators operating in bad weather:

Weather Assessment

• Wind Speed Check: Ensure winds are not in excess of the manufacturer's recommended operational levels. Refer to crane load charts for wind load capacities.
• Temperature Monitoring: Low temperatures will affect hydraulic fluid and equipment performance. Ensure the crane is adequately winterised.
• Visibility: Ensure visibility is sufficient to operate safely. Heavy rain or fog may require cessation or deferment of operations.

Site Conditions

• Assess Ground Stability: On snowy, icy, or wet ground, ensure that the ground will support the weight of the outriggers. If necessary, employ stabiliser mats.
• Snow and Ice: Check the outriggers, boom, and crane chassis for snow or ice. Clear any obstructions before operation.
• Pedestrian & Traffic Safety: On snowy or wet ground, ensure that there are signs and safety barriers to protect pedestrians and workers.

3. Crane Truck & Crane Checks

• Outriggers: Extend all outriggers and ensure they are securely grounded on solid ground. On uneven or icy ground, reposition outriggers.
• Boom & Hydraulic System: Check the hydraulic system for damage or freezing signs. Ensure smooth boom movement, especially in cold temperatures.
• Remote Control: Ensure that the remote control system is operational and that the crane's safety features (LSS-V, VSL Plus, etc.) are enabled.

4. Load Safety

• Load Weight and Position: Ensure that the load is with the crane's rated capacity under the existing weather conditions.
• Load Movement: Be cautious of swinging or moving loads, especially when operating under windy or stormy conditions.
• Tie-Down: Secure and balance all loads to prevent instability during lifting.

5. Operator Safety

• Proper Clothing: Ensure operators wear weather-appropriate clothing, including cold-weather gloves, high-visibility jackets, and slip-resistant shoes.
• Communication: Employ clear communication signals or radio communication among operators and ground personnel during poor visibility.
• Emergency Protocols: Review the emergency procedures for sudden changes in weather or unforeseen hazards.

6. Technology Checks

• HiConnect™ Telematics: Keep an eye on the telematics system for warnings concerning equipment condition, operational efficiency, or maintenance needs.
• Safety Systems: Ensure stability systems (VSL Plus, LSS-V) are current and in good working order.
• Automatic Speed Control: Ensure the ASC system is activated, especially on wet, slippery, or icy roads, for trouble-free and secure operation.

7. Environmental Concerns

• Water Runoff: Verify that water runoff from rain or snow is not collecting around the crane, leading to slipping hazards.
• Contaminants: Verify that the crane and the surrounding area are free from contaminants such as oil, mud, or ice that can hinder safe operations.

Final Check

Before commencing any lifting operation, the operator must make sure that the crane, site, and load are ready for operation under the existing weather conditions. If in doubt or danger, it's important to suspend operations and wait for an improvement in the weather.
