SAE J31-2012 液压挖掘机的提升能力

This document has been declared "Stabilized" and will no longer be subjected to periodic reviews for currency. Users are responsible for verifying references and continued suitability or technical requirements. New technology may exist. This standard applied to hydraulically operated backhoes (as defined in SAE J 1116). This standard describes a uniform "over end" and "full swing arc" lifting capacity rating for backhoes. It is based on the actual capacity of the machine to lift and support a load under stable conditions. Rated life capacities will be specified for both the boom and the dipperstick and will be shown on a lift capacity chart Figure 1. The purpose of this standard is to provide a uniform method of rating hydraulic backhoe lift capacities.
