3.1 SLING / LOAD BEARING DEVICE SAFETY
!
DANGER
A “LOAD-BEARING DEVICE” IS A CHAIN SLING, RIGID SLING, SPREADER BAR ASSEMBLY, FRAME, OR ANY
OTHER DEVICE THAT BEARS THE PARTIAL OR TOTAL WEIGHT OF THE EQUIPMENT FOR WHICH THIS MANUAL
HAS BEEN PRODUCED
THE LOAD-BEARING DEVICE SUPPLIED BY MCCOY GLOBAL IS DESIGNED TO SUPPORT THE EQUIPMENT DE-
SCRIBED IN THIS MANUAL. MCCOY GLOBAL WILL NOT GUARANTEE THE ABILITY OF THE LOAD-BEARING
DEVICE TO SUPPORT ANY OTHER PART, ASSEMBLY OR COMBINATION OF PARTS AND ASSEMBLIES. MC-
COY GLOBAL WILL NOT GUARANTEE THE ABILITY OF THE LOAD-BEARING DEVICE TO LIFT OR SUPPORT THE
EQUIPMENT DESCRIBED IN THIS MANUAL IF THERE ARE ANY MODIFICATIONS TO THE LOAD-BEARING DEVICE,
OR ANY ADDITIONS TO THE EQUIPMENT DESCRIBED IN THIS MANUAL THAT ADD WEIGHT TO THE EQUIPMENT,
UNLESS SUPPLIED BY MCCOY GLOBAL.
!
WARNING
WHEN RE-ASSEMBLING LOAD-BEARING DEVICES (CHAIN SLINGS, RIGID SLINGS, BACKUP LEGS, ETC.) NOTE
THAT THE ASSOCIATED FASTENERS MUST BE TIGHTENED TO THE CORRECT TORQUE SPECIFIED FOR THAT
SIZE OF FASTENER (SEE MAINTENANCE SECTION). ANY THREADED FASTENER IN A LOAD-BEARING DEVICE
MUST BE SECURED WITH RED OR BLUE LOCTITE™.
REPLACEMENT FASTENER (BOLTS, NUTS, CAP SCREWS, MACHINE SCREWS, ETC.) USED DURING
MAINTENANCE OR OVERHAUL MUST BE GRADE 8 OR EQUIVALENT UNLESS OTHERWISE SPECIFIED.
McCoy Global recommends following an industry-accepted standard such as OSHA, ASME B30.9-2006, or manufac-
turer’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.
• Use only Grade 80 or Grade 100 alloy chain for overhead lifting applications.
• Working Load Limit (WLL) is the maximum allowable load in pounds or kilograms 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.
• 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/
ASME B30.26 “RIGGING HARDWARE” for additional information.
3.1.1 Inspection Of Load-Bearing Devices and Structures
McCoy strongly recommends the following practices:
A complete inspection of new load-bearing devices and attachments shall be performed by a qualified, designated
person prior to initial use. Each component shall be examined individually, taking care to expose and examine
all surfaces including the inner link surface. In addition, daily inspection of fastenings and attachments shall be
performed by a designated person. If damage or defects are found at either inspection, the damaged or defective
component shall be quarantined from service until it can be properly repaired or replaced.
Removal Criteria:
A load-bearing device shall be removed from service if conditions such as the following are present:
• Cracks or breaks
• Evidence of tampering is seen - for example, tamper-proof nuts are missing.
• Signs of impact on load-bearing components, including spreader bars, lifting lugs, rigid slings & rigid sling
weldments, and legs & leg mounts.
• Broken or damaged welds.
• Excessive wear, nicks, or gouges.
• Excessive pitting of the components due to rust and/or corrosion
!
WARNING
IF THE LOAD-BEARING DEVICE HAS BEEN MECHANICALLY DAMAGED OR OVERLOADED, IT MUST
BE IMMEDIATELY REMOVED FROM SERVICE AND QUARANTINED UNTIL IT HAS BEEN RECERTIFIED.
3.1.1 Inspection Of Load-Bearing Devices and Structures (Continued):
Inspect all lugs and fixing points for signs of elongation and/or bending, or for material build-up around the hole.
Repair or replace components that appear distorted. Ensure all hardware is tight and in good condition. Replace
missing hardware if necessary. All hardware must be free of rust and corrosion. Additional inspections shall be
performed where service conditions warrant (a maritime environment, for instance). Periodic inspection intervals
shall not exceed one year. The frequency of periodic inspections should be based on:
• Frequency of use of the load-bearing device.
• Severity of service conditions
• Experience gained on the service life of load-bearing devices used in similar circumstances.
General guidelines for the interval are:
• Normal Service - yearly
• Severe Service - monthly to quarterly
• Special Service - as recommended by a qualified person
McCoy recommends that all users of lifting or load-bearing assemblies establish inspection criteria, or adopt a
relevant inspection standard assigned to a competent inspection body. McCoy recommends an inspection schedule
similar to that listed in the following table.

1. Load test(s) as established by end user’s inspection criteria. McCoy recommends testing to two times MGW
(maximum gross weight) or in the case of spring hangers, as indicated in Section 5.
2. For the purposes of this standard, a substantial repair or modification is defined as any repair and/or
modification that has been carried out which may, in the opinion of the inspection body, affect the load-bearing
elements of the container or lifting device, or elements that contribute directly to its structural integrity.
Refer to the following table to determine proper test load when pull-testing spring hangers,
Model Number WLL (lbs) WLL (kg) Test Load (lbs) Test Load (kg)
85-0106X (SX) 1200 544 2500 1133
85-0106XXH 2400 1088 5000 2267
85-0106HDS 5900 2676 7900 3583
85-0106HD 11500 5216 15500 7030
55-0000030 13,000 5906 36,000 16,356
Record the inspection dates and results in a visible location, including a description of the condition of the load-
bearing equipment. To avoid confusion, do not list the date of the next test or examination, only the most recent.
