What is a potential consequence of not accounting for boom deflection when lifting a load?

1. The load may drop

2. The load may swing away from the crane

3. The load may weigh more than expected

4. The load may cause equipment damage

The correct answer is: The load may swing away from the crane

When lifting a load, accounting for boom deflection is crucial because it directly impacts the stability and positioning of the load. Boom deflection is the amount of bending or sagging that occurs in the boom of the crane when a load is applied. If this deflection is not taken into consideration, it can result in the load swinging away from the crane. This swinging motion can pose serious safety hazards, such as the load potentially striking nearby personnel or equipment and increasing the risk of losing control over the load. Understanding and compensating for boom deflection ensures that operators can maintain the intended path and control during the lift, allowing for safer operations. Proper planning and awareness of boom deflection contribute to maintaining the load’s stable position in the lift and reducing the likelihood of accidents.
