What is one reason to use a friction brake in a rigging operation?

Using a friction brake in a rigging operation primarily serves to control the descent speed of the load. By applying friction, the brake can modulate the rate at which the load descends, allowing for safer and more precise control during lifting and lowering operations. This is particularly valuable in situations where a load may need to be lowered carefully or at a controlled speed to prevent sudden movements that could lead to accidents or damage to the load or surrounding structures.

Controlling descent speed is crucial in various applications, especially near sensitive environments or when handling fragile materials. This operational control enhances safety for the crew involved and contributes to the overall effectiveness of the rigging process.
