It is identical with ISO 5998:1986 “Earth-moving machinery Rated operating load for crawler and wheel loaders” published by the International Organization for Standardization (ISO). ISO 5998 was produced as a result of inter
9、national discussion in which the UK took an active part. Terminology and conventions. The text of the International Standard has been approved as suitable for publication as a British Standard without deviation. Some terminology and certain conventions are not identical with those used in British St
10、andards; attention is drawn especially to the following. Wherever the words “International Standard” appear, referring to this standard, they should be read as “Part of BS 6912”. A British Standard does not purport to include all the necessary provisions of a contract. Users of British Standards are
11、 responsible for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations.

14、2-2:1989 BSI 09-19991 1 Scope and field of application This International Standard specifies the comparative rated operating load for both crawler and wheel loaders. The rated operating load is based only on the machines lifting capacity, static forward tipping load, and specified operating conditio
15、ns. NOTEThe actual operating load, practical on a specific job for a given machine, can vary from the rated operating load on the basis of the job conditions. 2 References ISO 7546, Earth-moving machinery Loader and front loading excavator buckets Volumetric ratings.
