Final answer:
If the operator does not account for boom deflection when lifting a load, it can cause unpredictable movement and potential accidents. It is important for operators to consider boom deflection and adjust lifting techniques to ensure safety.
Step-by-step explanation:
When a load is lifted off the ground by a crane, the boom of the crane can experience deflection, which means it bends or sags under the weight of the load. If the operator does not take this deflection into account, a properly rigged load may swing or move unpredictably. This can be dangerous as it can cause accidents or damage to the load or equipment.
For example, imagine a crane picking up a heavy object with a long boom. If the operator does not account for the deflection or bending of the boom when the load is lifted, the load could swing sideways or tilt, potentially hitting nearby objects or causing instability.
To ensure safe and stable lifting operations, it is crucial for operators to consider the deflection of the boom and adjust their lifting techniques accordingly, such as using counterweights or changing the angle of the boom.
