In accordance with API-2C, values shown are acutal hook
load (weight of block and hook excluded).
Load line block weight is 113 kgs.
Load line (2 part line): 9/16" 19x7 EIPS-IWRC; 11,363 lbs. breaking
strength; 2,272 lbs. working strength.
Static load = 1.5 x dynamic load
Pedestal reactions are based on three times the dynamic load plus the
dead load.
