What is referred to as the distance from the inside of a sling's upper end fitting to its lower end fitting?

The term that describes the distance from the inside of a sling's upper end fitting to its lower end fitting is referred to as "reach." This measurement is crucial in rigging and hoisting as it indicates how far the load can be lifted or extended from the point of attachment. Understanding the reach helps in planning lifts to ensure that the lift will clear any obstacles and that the load can be safely maneuvered.

While "length," "height," and "drop" may pertain to various aspects of rigging, they are not specific to the definition provided. "Length" typically refers to the total length of the sling, not taking into account the fitting placements. "Height" is more related to vertical measurements, often concerning the elevation of the load or the lift. "Drop" indicates the distance the load is lowered, which doesn't convey the same information as the reach. Thus, recognizing "reach" as the accurate term enhances the understanding of sling configurations and their applications in hoisting operations.
