What is the function of a rigging wrench?

A rigging wrench is specifically designed to assist in tightening or securing rigging hardware. This tool is crucial in ensuring that connections such as shackles, turnbuckles, or other rigging components are properly tightened to maintain safety and stability during lifting operations. When using a rigging wrench, the rigger can apply the necessary torque to ensure the hardware does not loosen during use, which is vital for the integrity of the load being lifted.

While lifting heavy loads is an important aspect of rigging, that task is typically handled by cranes or other lifting devices, not by the wrench itself. Similarly, measuring load weight generally requires scales or load cells and is not a function of a rigging wrench. Creating slings involves using rope, chain, or webbing and does not pertain to the functions of a wrench. Thus, option B accurately reflects the primary function of a rigging wrench in the rigging process.
