Product Code:SAE J818
Title:Rated Operating Load for Loaders
Issuing Committee:Mtc1, Loaders, Crawlers, Scrapers And Mounted Attachments
Scope:This SAE Standard establishes the definition of a normal all day rated operating load for loaders as defined in SAE J1057. This SAE Standard applies to wheel and crawler loaders taking only hydraulic lift capacity and tipping capacity into consideration. It is recognized that specific operating conditions may allow larger, or require smaller loads than the rated operating load. Some conditions could require more careful or restricted operation with the rated operating load. This standard is not to be construed as setting up test procedures or conditions.【英文标准名称】:Lightningprotection-Telecommunicationlines-Part1:Fibreopticinstallations
