Overhead Crane Practice Test

At what horizontal sling angle should it be maintained if possible?

1. 45 degrees

2. 30 degrees

3. Greater than 60 degrees

4. Less than 36 degrees

The correct answer is: Greater than 60 degrees

Maintaining a horizontal sling angle greater than 60 degrees is essential for several reasons. Firstly, a sling angle that is too shallow can increase the risk of the load slipping off the sling or becoming unstable during lifting. When the angle is greater than 60 degrees, it reduces the potential for excessive stress on the sling and the lifting equipment, thereby enhancing the load’s stability. Additionally, a shallower angle can result in a greater force being applied to the sling, placing it under more strain and potentially leading to a failure of the lifting apparatus or causing accidents. Maintaining a higher angle helps to distribute the load more evenly across the sling, thus promoting safer lifting operations and adhering to best practices in sling use. While other options suggest maintaining a different degree of angle, they do not provide the same level of safety and stability during lifting operations. Therefore, aiming for a horizontal sling angle greater than 60 degrees is a recommended practice to ensure the effective and safe handling of loads.
