Study Notes
Crane Operations and Safety
- A signal person must be used when the crane operator's view is obstructed, ensuring safe lifting operations.
- The assembly/disassembly director is responsible for overseeing and directing all crane assembly and disassembly processes to maintain safety standards.
Load and Stability
- The center of gravity is the point in an object where its weight is evenly distributed, crucial for maintaining stability during lifting.
- Cranes placed on uneven surfaces may have limited load ratings, increasing the risk of accidents.
- Inadequate ground conditions can lead to crane toppling, even when loads are within the crane's maximum capacity.
Equipment and Indicators
- Sheaves are wheels on a crane with open grooves that guide ropes or cables, essential for lifting operations.
- A boom angle indicator is required for cranes and derricks set up on floating surfaces, ensuring operators have clear visibility of the boom's angle.
Worker Safety
- Personal platforms can be used to raise and lower workers only when other access methods are deemed more dangerous or impossible, emphasizing the importance of worker safety.
- Grab-rails provide additional safety by offering something to hold onto if a personal platform shifts unexpectedly during operation.
