Red Seal Ironworker (Structural/Ornamental) Practice Exam

Why is a choker hitch preferred for certain rigging tasks?

1. It is easier to untie

2. It allows for load flexibility

3. It creates a stable lift that tightens on the load

4. It can only be used for lightweight loads

The correct answer is: It creates a stable lift that tightens on the load

A choker hitch is preferred for certain rigging tasks because it creates a stable lift that tightens on the load as tension is applied. This feature is particularly advantageous when the load is being lifted, as the hitch will grip the load more securely as it rises, reducing the risk of slippage. The ability of the choker hitch to adjust and conform to the load means that it can maintain a secure hold during dynamic movements, which enhances safety and control during lifting operations. In contrast, while ease of untying is valuable, it's not the primary reason for the use of a choker hitch. Load flexibility is more a characteristic of other lifting configurations rather than a specific advantage of the choker hitch. Finally, the capacity of the hitch is not limited to lightweight loads; it can be used for a wide range of weights, making it versatile in various rigging applications.
