In accordance with API-2C, values shown are acutal hook load (weight of block and hook excluded).

Load line block weight is 250 lbs.
Load line (2 part line): 9/16" 19x7 EIPS-IWRC; 25,000 lbs. breaking strength; 5,000 lbs. working strength.

Static load = 1.5 x dynamic load
Pedestal reactions are based on three times the dynamic load plus the dead load.
