1 USER S GUIDE LIFTING API RP2D Version (06/06) REFER TO API RP2D FOR FULL DETAILS RISK MANAGEMENT DEFINITION COMPREHENSIVE SET OF ACTIONS THAT REDUCES THE RISK OF A PROBLEM, A FAILURE, AN ACCIDENT Quality Continuum TERMINOLOGY WORKING LOAD LIMIT (WLL) THE MAXIMUM MASS OR FORCE WHICH THE PRODUCT IS AUTHORIZED TO SUPPORT IN A PARTICULAR SERVICE. PROOF TEST A TEST APPLIED TO A PRODUCT SOLELY TO DETERMINE INJURIOUS MATERIAL OR MANUFACTURING DEFECTS. ULTIMATE STRENGTH THE AVERAGE LOAD OR FORCE AT WHICH THE PRODUCT FAILS OR NO LONGER SUPPORTS THE LOAD. DESIGN FACTOR AN INDUSTRIAL TERM DENOTING A PRODUCT S THEORETICAL RESERVE CAPABILITY; USUALLY COMPUTED BY DIVIDING THE CATALOG ULTIMATE LOAD BY THE WORKING LOAD LIMIT. GENERALLY EXPRESSED AS A RATIO, e.g. 5 TO 1. FOR ADDITIONAL SUPPORT P.O.

THE CAPACITY OF A BRIDLE AT A 30 DEGREE HORIZONTAL IS SAME AS SINGLE VERTICAL LEG. RATED LOAD BASED ON FITTING DIAMETER NO LARGER THAN ONE HALF THE NATURUAL EYE LENGTH AND NOT LESS THAN THE NOMINAL SLING DIAMETER BASKET HITCH CAPACITY BASED ON MINIMUM D/d RATIO OF 25/1 FOR CHOKER HITCH, THE ANGLE OF CHOKE SHALL BE 120 DEGREES OR GREATER 9

PLACING ALL SLINGS ON HOOKS AND PINS NEVER PLACE A SLING EYE OVER A FITTING WITH A DIAMETER OR WIDTH GREATER THAN ONE HALF THE NATURAL LENGTH OF THE EYE A CHOKER HITCH OF ALL SLINGS HAVE 70% TO 80% OF THE CAPACITY OF A SINGLE LEG ONLY IF THE CORNERS ARE SOFTENED AND THE HORIZONTAL ANGLE IS GREATER THAN 30 DEGREES. USE A BLOCK OF WOOD UNDER CHOKE TO INSURE ANGLE IS PROPER. 10 ALL SLINGS A BASKET HITCH HAS TWICE THE CAPACITY OF A SINGLE LEG ONLY IF D/d RATIO IS 25/1 AND THE LEGS ARE VERTICAL.
