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.
