McCoy Drilling & Completions recommends following an industry-accepted standard such as OSHA, ASME B30.9-2006, or manufacturer’s
guidelines when performing any rigging and overhead lifting. Use by untrained persons is hazardous. Improper use will result in serious
injury or death. Do not exceed rated capacity. Slings will fail if damaged, abused, misused, overused, or improperly maintained.
• Only grade 80 or grade 100 alloy chain should be used for overhead lifting applications.
• Working Load Limit (WLL) is the maximum allowable load in pounds which may be applied to the load-bearing device, when the device
is new or in “as new” condition, and when the load is uniformly and directly applied. The WLL must never be exceeded.
• Working Load Limit (WLL) is the maximum working load for a specific minimum sling angle, measured from the horizontal plane. The
Working Load Limit is identified on the sling.
• The Working Load Limit or Design factor may be affected by wear, misuse, overloading, corrosion, deformation, intentional alterations,
sharp corner cutting action and other use conditions.
• Shock loading and extraordinary conditions must be taken into account when selecting alloy chain slings.
• See OSHA Regulation for Slings 1910.184, ANSI/ASME B30.9-”SLINGS”, ANSI/ASME B30.10-”HOOKS” and ANSI/AMSE B30.26
“RIGGING HARDWARE” for additional information.
DO NOT ACCESS ROTATING COMPONENTS UNLESS HYDRAULIC POWER SUPPLY HAS BEEN
DEACTIVATED OR ISOLATED.
A CLEARLY IDENTIFIED REMOTE POWER PACK EMERGENCY STOP MUST BE INSTALLED IN THE
IMMEDIATE VICINITY OF THE TONG OPERATOR.
Adequate setup and proper hydraulic connections are essential in ensuring reliable operation of your tong. For best results and long term reli-
ability, read and obey the start-up instructions in this section.
THE SUPPLIED LOAD-BEARING DEVICE (CHAIN SLING, RIGID SLING, SPREADER BAR ASSEM-
BLY, FRAME, OR ANY OTHER DEVICE THAT BEARS THE PARTIAL OR TOTAL WEIGHT OF THE
EQUIPMENT DESCRIBED IN THIS MANUAL) HAS BEEN SPECIFIED OR DESIGNED TO SUPPORT
THE EQUIPMENT DESCRIBED IN THIS DOCUMENT. FARR® WILL NOT GUARANTEE THE ABILITY
OF THE LOAD-BEARING DEVICE TO SUPPORT ANY OTHER PART, ASSEMBLY OR COMBINATION
OF PARTS AND ASSEMBLIES, OR ANY ADDITIONS TO THE EQUIPMENT DESCRIBED IN THIS
MANUAL THAT ADD WEIGHT TO THE EQUIPMENT, UNLESS SUPPLIED BY MCCOY.
MCCOY DRILLING & COMPLETIONS DOES NOT GUARANTEE THE INTEGRITY OF MODIFIED OR
DAMAGED LOAD-BEARING DEVICES, UNLESS THOSE MODIFICATIONS ARE PERFORMED BY
MCCOY.
THE MINIMUM SLING ANGLE (THE ANGLE OF THE LEG OF THE SLING MEASURED
FROM THE HORIZONTAL) MUST NEVER FALL LOWER THAN THE ANGLE SPECIFIED
FOR THE SLING IN USE
