Why is calculating hitch tension important rather than using the load weight directly to select rigging?
A
Sling angle, hitch type, and number of legs all affect the force on each sling - using load weight without these calculations risks overloading the gear
B
Calculation is not needed if color-coded slings are used
C
Tension is always less than load weight so overload is impossible
D
Load weight and hitch tension are always equal for all hitch types
