What is the maximum angle when using a sling?

The maximum angle when using a sling is 60 degrees from the vertical. This angle is significant because as the angle of the sling increases, the load's effective weight on the sling increases due to the horizontal component of the force acting on it. When the sling is used at an angle greater than 60 degrees, the stress on the sling increases considerably, which can lead to potential failure. Keeping the angle at or below 60 degrees helps to maintain the integrity of the sling and the safety of the lifting operation. This practice is crucial for ensuring that the lifting equipment operates within safe limits and reducing the risk of accidents or equipment failure during lifting operations.
