This standard applies to hydraulically operated backhoes (as defined in SAE J1116) 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 lift capacities will be specified for both the boom and the dipperstick and will be shown on a lift capacity chart Figure 1. This revision of existing SAE J31 has been expanded to include a calculated method of determining lift capacities. This is a common practice in the industry and is also used on similar equipment such as hydraulic excavators.
