Harrington Hoists and Cranes HSC Sling Chain - Manual (Page 2)

NOTICE
It is the responsibility of the owner/user to install, inspect, test, maintain, and use the sling in accordance with ANSI/ASME B30.9, “Safety
Standards for Slings”, ANSI/ASME B30.20, “Safety Standard for Below-the-Hook Lifting Devices” and OSHA Regulation 1910.184. If the
sling is installed as part of a total lifting system, such as an overhead hoist, crane or monorail, it is also the responsibility of the
owner/user to comply with the applicable ANSI/ASME B30 volume that addresses that type of equipment.
It is the responsibility of the owner/user to have all personnel that will install, inspect, test, maintain, and use the sling read the contents
of this document and applicable portions of ANSI/ASME B30.9, “Safety Standards for Slings”, ANSI/ASME B30.20, “Safety Standard for
Below-the-Hook Lifting Devices”, where applicable, ANSI/ASME B30.16, “Safety Standards for Overhead Hoists (Underhung)”,
ANSI/ASME B30.21, “Safety Standard for Manually Lever Operated Hoists” and OSHA Regulation 1910.184.
If the sling owner/user requires additional information, or if any information in this document is not clear, contact Harrington Hoists, Inc.
or the distributor of the sling. Do not install, inspect, test, maintain, or use the sling unless this information is fully understood.
A regular schedule of inspection of the sling in accordance with the requirements of ANSI/ASME B30.9, ANSI/ASME B30.20 and where
applicable, ANSI/ASME B30.16 and ANSI/ASME B30.2 should be established and records maintained.
2.0 Technical Information
2.1 Specifications
2.1.1 Operating Conditions and Environment:
Temperature: Refer to table 2-1 for the effect of temperature conditions on proper use of the sling chain.
Table 2-1 Temperature Conditions
Temperature Reduction of Working Load Limit
°F °C While at Temperature After Exposure to Temperature
-40 to 400 -40 to 204 None None
400 204 15% None
500 260 25% 5%
600 316 30% 15%
700 371 40% 20%
800 427 50% 25%
900 482 60% 30%
1000 538 70% 35%
Humidity: 100% or less. This chain is not intended for underwater use.
Corrosive, acidic, or
alkaline environments:
DO NOT USE in environments that are alkaline, acidic or corrosive.
Damaging effects are dependent upon chemical type, concentration, temperature and length of exposure.
It is the responsibility of the owner/user to identify and eliminate or avoid such environments. If required,
contact Harrington Hoists, Inc. for guidance.
Dynamic Loading: REDUCE LOAD to 80% of working load limit (WLL) when loading conditions are at/near WLL, or if the
sling chain is subject to vibration, or if the sling chain is used in a demanding application such as an
automated production line. ALWAYS consider the effects of dynamic or accelerated loads when
selecting or sizing sling chain.
