The above loads are in compliance with hydraulic excavator lift capacity standard ISO 1067:2007. They do not exceed 87% of hydraulic lifting capacity or 7% of tipping load. Weight of all lifting accessories must be deducted from the above lifting capacities. Lifting capacities are based on the machine standing on a firm, uniform supporting surface. The use of a work tool attachment point to handle/lift objects, could affect the machine lift performance. Lift capacity stays with ±% for all available track shoes.

Use of work tools, including buckets, which are outside of Caterpillar s recommendations or specifications for weight, dimensions, flows, pressures, etc. may result in less-than-optimal performance, including but not limited to reductions in production, stability, reliability, and component durability. Improper use of a work tool resulting in sweeping, prying, twisting and/or catching of heavy loads will reduce the life of the boom and stick. 7
