Free OSHA Load Handling & Rigging Techniques Questions and Answers

Question 1

What is the main purpose of rigging in crane operations?

Accepted Answer

Secure and balance the load

Answer

The main purpose of rigging in crane operations is to safely secure and balance the load for lifting. Proper rigging involves selecting the correct slings, shackles, and other hardware, and attaching them in a way that distributes the load evenly and prevents it from shifting or falling during the lift. This is critical for maintaining stability and ensuring the safety of the entire operation.

Question 2

Which type of hitch is best for lifting round objects?

Accepted Answer

Choker hitch

Answer

The choker hitch is particularly effective for lifting round objects because it tightens around the load as tension is applied, providing a secure and self-cinching grip. This action helps prevent the load from slipping out of the sling during the lift. It is a common and safe method for handling items like pipes, poles, and other cylindrical materials.

Question 3

What is the term for the maximum weight a sling can safely lift?

Accepted Answer

Working load limit

Answer

The Working Load Limit (WLL) is the maximum weight a sling or any rigging component can safely lift under normal operating conditions. Exceeding the WLL can cause the rigging to fail, leading to catastrophic accidents and potential fatalities. It is absolutely crucial to always know and adhere to the WLL for all lifting equipment to ensure safety.

Question 4

Which of the following is a key inspection point for rigging equipment?

Accepted Answer

Wear or damage

Answer

A key inspection point for all rigging equipment is to meticulously check for any signs of wear or damage, such as cuts, nicks, deformation, corrosion, or frayed fibers. Even minor damage can significantly compromise the strength and safety of the rigging, potentially leading to failure during a lift. Any damaged equipment must be immediately removed from service.

Question 5

Why is load angle important in rigging?

Accepted Answer

Influences sling tension

Answer

The load angle, which is the angle at which the sling legs meet the load, is critically important because it directly influences the tension on each sling leg. As the angle decreases (meaning the sling legs become flatter), the tension on each leg increases significantly, potentially exceeding the sling's Working Load Limit. Maintaining proper load angles is essential for safe load distribution and preventing sling failure.
