Description / Abstract:
Steel chains of the type covered by this Standard were first
introduced in the late 1930s. These
chains met with considerable success on material conveying
applications.
In 1973, a subcommittee of American National Standards Committee B29
was appointed to draft a
standard for these hinge type flat top conveyor chains. This Committee
was composed of interested
members of the American Chain Association.
The standard developed by this Committee covered only those dimensions
that affect
interchangeability and interconnectability.
To promote the use of this Standard in international trade, metric
equivalents of all dimensions
and capacities are given.
The American National Standards Institute approved the previous
edition of this Standard on June
21, 1983, and it was reaffirmed in 1995.
The Standard was modified in 1997 to include two straight running
nonmetallic chains (24P26 and
24P86). This edition received ANSI approval on September 9, 1998.
