Product Code:SAE J2513
Title:Earthmoving Machinery-Coupling of Attachments to Skid Steer Loaders
Issuing Committee:Mtc1, Loaders, Crawlers, Scrapers And Mounted Attachments
Scope:This SAE Standard sets forth standard dimension requirements for the loader attachment bracket and attachment interface to allow interchangeability of attachments on skid steer loaders whose operating mass (see SAE J/ISO 6165) is 4,500 kg or less. Narrow skid steer loaders may have a width that does not allow compliance with this standard.【英文标准名称】:Rawopticalglass-Grindabilitywithdiamondpellets-Testmethodandclassification
