ISO 3077:2001 PDF

Scope: This standard specifies the requirements for high-precision hoist chains of grade T (type T, DAT and DT) for manual hoists or power-driven chain hoists. This standard is applicable to round steel electric welded short rings with a nominal size range of 3 mm to 22 mm. The heat treatment and testing of the chain shall be in accordance with the general acceptance rules specified in GB/T 20946. Note: T-type chains other than DAT or DT types can be used not only for chain hoists, but also for TH and VH dedicated to other manual hoists. Grade chains will be specified in other standards.
