What is the typical range of reeving mechanical advantage in various arrangements?

The typical range of reeving mechanical advantage in various arrangements is generally understood to be between 2 to 5. This means that for a given input force applied to a system of pulleys, the output force can be multiplied by a factor within this range, allowing for enhanced lifting capability.

In practical terms, a mechanical advantage of 2 means the force applied is effectively doubled at the load end, making it easier to lift heavy objects. The upper limit of this range, 5, allows for even more significant force multiplication, enabling the lifting of much heavier weights with the same input effort.

This range is governed by the configuration of the pulleys and the number of reeves in use but is standardized in many applications to ensure efficiency and safety in lifting operations. Lower mechanical advantages make systems easier to manage but require more input force, while those at the higher end offer considerable lifting power with a trade-off in increased complexity and potential for mechanical loads on the rigging and pulleys.

In contrast, other ranges suggested by different options are not as commonly observed in standard applications, which tend to favor the 2 to 5 range for practical and ergonomic reasons.
