This standard specifies the unified method for calculating the lifting capacity of hydraulic excavators and the test procedures for verifying their calculated values, including the determination of the hydraulic lifting capacity limit of hydraulic excavators and the tipping limit of the machine, as well as the rated lifting capacity. This standard applies to hydraulic excavators defined in ISO 7135.
