Load Increase Factors = 1.25 (or as appropriate)
Strength Reduction Factors = 0.9 (or as appropriate)
(Ultimate Strength) x (Strength Reduction Factors)
(Design Limit Load) x (Loan Increase Factors)
Ultimate Strength: The ultimate breaking strength of the wire
ropes as certified by the manufacturer.
Strength Reduction Factors: Those factors which reduce the
static load breaking strength such as terminating with
wire rope clips (.8) or a clove hitch (.65)
Design Limit Load: The weight the wire rope is to lift.
Load Increase Factors: Those variable factors that may in-
crease the load above its design limit, such as a curtain absorbing moisture from the atmosphere (1.15), a
point load on a batten (1.25), normal motor torque
increase (1.5), starting inertia or pully friction.
