25、ed in 1985. It was developed by the ASME HST Standards Committee, Hoists Overhead. It is intended to serve as a guide to manu-facturers of the equipment and to the purchasers and users of the equipment.Standards in this series are:HST-1, Performance Standard for Electric Chain HoistsHST-2, Performan
26、ce Standard for Hand Chain Manually Operated Chain HoistsHST-3, Performance Standard for Lever HoistsHST-4, Performance Standard for Overhead Electric Wire Rope HoistsHST-5, Performance Standard for Air Chain HoistsHST-6, Performance Standard for Air Wire Rope HoistsThis edition contains an appendix
27、 that, in conjunction with ASME HST-3, is intended to replace MIL-H-904.ASME HST-32017 is rewritten and reorganized to conform to current ASME style guidelines and harmonized withASME B30.21 to eliminate duplication and conflicts in content. The title is revised to “Performance Standard for LeverHoi
28、sts.”Definitionshavebeenrevised.The2017editiondoesnotincludeacorrespondingsectiontoASMEHST-31999(R2010), Section 3: Mechanical, due to duplication with ASME B30.21. This revision also includes the addition of speci-ficationsandfiguresforleverhoistswithweb-strap typeandwire-ropetypeliftingmedia,andth
