Working with gantry cranes during nighttime or in low-light conditions presents unique challenges. While meeting project deadlines may necessitate overtime, it’s crucial to prioritize safety for both operators and equipment. Here are key precautions to ensure safe operations:
Adequate Lighting Setup:
- Prior to nighttime operations, ensure sufficient lighting is installed. For outdoor work, use tungsten iodide lamps, while in enclosed spaces or near pressure vessels, opt for safe traveling lamps.
Illumination in Work Areas:
- Ensure that the construction area around the gantry crane is well-lit to improve visibility and reduce the risk of accidents.
Emergency Preparedness:
- Operators should keep flashlights on hand for emergencies. This ensures they can navigate safely should the main lighting fail.
Power Supply Safety:
- After completing work, always cut off the power supply to the gantry crane before leaving the site to prevent potential fire hazards.
Control Circuit Integrity:
- The gantry crane’s control circuit must be correctly installed and free from errors, false circuits, or parasitic connections. Any malfunction in the control system could lead to automatic shutdowns.
Lifting Solenoid Circuit:
- For AC gantry cranes, establish a dedicated DC power supply for the lifting solenoid. Consider having a backup power supply to ensure consistent operation and safety.
By following these precautions, operators can enhance safety during nighttime operations with gantry cranes, minimizing risks and ensuring efficient workflow.
