J31_198603 HYDRAULIC BACKHOE LIFT CAPACITY

This standard applies to hydraulically operated backhoes (see SAE J49).

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.
