12、a successful size chain,or family of chains,others soon duplicated it and a large number of chains came into being.In spite of efforts at standardization,the Corps of Engineers,United States Army,found during the Korean incident of 1950-53 that lack of adequate standardization of power transmission
13、chains still resulted in the incapacitation of many cranes and shovels.For this reason,the Corps of Engineers requested the Society of Automotive Engineers to expand the scope of ASA Sectional Committee B29 to cover this group of chains.On May 13,1956,the Corps of Engineers request was approved by t
14、he ASA B29 Committee and the ASA B29.10 Subcommittee was formed.Upon approval by the American Standards Association in April 1962;the first standard for ASA B29.10 chains and sprockets was published.The Standard described the physical dimensions of the chain components and sprockets,and defined the
15、minimum static properties for the chains.In 1970,this Standard was revised to include Drive Selection information in a Supplementary Section and to convert fractions to decimal-inch,and include metric dimensions in SI Units.In September 1962,the Engineering Steel Chain Division of the ACA began a re
16、search program to develop ratings for the ANSI B29.10 chains.Capacity information on the smaller B29.1 chains already developed in research programs sponsored by the Roller Chain Division of the ACA was made available to the Engineering Steel Chain Division.Member companies contributed information from their own research programs.Special dynamic test equipment was built to enable obtaining wear and capacity data on very large chains.The horsepower capacities published as supplementary informatio
