COLUMBUS McKINNON - Lifting chain – Grade 100
2019-01-17 08:34:07GREATER STRENGTH - LOWER WEIGHT
(INCREASED FORCE - LIGHTER WEIGHT)
Because accessories and grade 100 chains have higher operating loads than grade 80, users enjoy a greater operating load with a lighter weight.
MORE RESISTANCE TO ABRASION
Replace chains less often. Grade 100 reduces wear on exterior links
lying on the ground or in regular contact with abrasives.
HIGHER MAXIMUM LOADS
Have more power with a smaller diameter. Our grade 100 chain is 25%
stronger than the grade 80 alloy chain.
UNIQUE METALLIC PROPERTIES
Its special chemistry and heat treatment make the grade 100 chain
the strongest to date.
EXTENDED LIFE
Grade 100, harder, reduces wear on the inner linkage associated with
normal wear, extending the life of the lifting system.
EMBOSSING
Grade 100 chain is embossed with its grade and a date code at intervals
not exceeding one foot for greater traceability.
Sold at the foot or barrel
Columbus grade 100 chain finished is matte black.
Meets ASTM & NACM 973 standards
