To determine whether your sling angle will be greater than 60 degrees before operations, we need to follow a structured approach. Here’s a detailed step-by-step process:
1. Check the Length of the Slings:
Ensure that the slings are more than 6 feet (1.8 meters) long. This is the preliminary step to verify that we are working with sufficiently long slings.
2. Measure the Distance Between Pick Points:
Lay one end of a sling at one pick point and check that it reaches past the other pick point. This provides a basic verification to ensure that the slings are of adequate length to span the distance between the pick points.
3. Set Up Rigging and Measure the Angle:
Rig the load as intended for the operation. Once the load is rigged, use a protractor to measure the angle between the sling and the horizontal plane. The goal is to determine if this angle is greater than 60 degrees.
- To use the protractor:
1. Position it at the point where the sling makes contact with the load.
2. Line up the base of the protractor with the horizontal plane.
3. Measure the angle where the sling intersects the protractor scale.
If the measured angle where the sling makes contact is greater than 60 degrees, then the sling angle is indeed more than 60 degrees. If it’s less, then adjustments might be needed to achieve the desired angle.
Following these steps ensures a thorough assessment of whether your sling angle is greater than 60 degrees before commencing operations.
