1  Scope
This International Standard provides the dimensions of operators of earth-moving machinery as defined in ISO 6165 and specifies the minimum normal operating space envelope within the operator enclosures. It is not applicable to machines manufactured prior to the date of its publication.
2  Normative references
The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. ISO 5353:1995, Earth-moving machinery, and tractors and machinery for agriculture and forestry — Seat index point ISO 6165:2006, Earth-moving machinery — Basic types — Identification and terms and definitions ISO 11112:1995, Earth-moving machinery — Operator’s seat — Dimensions and requirements
3  Terms and definitions
For the purposes of this document, the following terms and definitions apply. 3.1 small operator operator belonging to the worldwide earth-moving machinery operator population where approximately 5 % of operators are smaller than the dimension listed 3.2 medium operator operator belonging to the worldwide earth-moving machinery operator population where approximately 50 % of operators are smaller than the dimension listed and the remaining worldwide earth-moving machinery operator population is larger than the dimension listed 3.3 large operator operator belonging to the worldwide earth-moving machinery operator population where approximately 5 % of operators are larger than the dimension listed 3.4 working posture posture an operator assumes while doing work 3.5 erect posture standing or sitting upright without a backrest
4  Physical dimensions of operators
The ranges of physical dimensions for standing and seated operators are shown in Figures 1 and 2. The ranges of derived body pivot dimensions are shown in Figure 3. The dimensions include a 25 mm allowance for the height of shoes or boots. The influence of other clothing is insignificant on these dimensions. All dimensions are for an operator in an erect posture. A working posture is typically relaxed and the dimensions will be slightly less: stature (1A) and overhead reach (2A) will be reduced by about 15 mm, while sitting height (3A) and sitting eye height (3B) will be reduced by about 25 mm. In some areas of the world, more than 5 % of the operators have leg lengths less than the values given for the small operators. To accommodate these areas, special adjustments may be provided.
5  Minimum operator space envelope
5.1  General The minimum operator space envelope is the interior dimension of the operator’s enclosure. The minimum operating space envelope around the operator for operator enclosures (e.g. cabs, ROPS, FOPS) is shown in Figure 4 for a seated operator and in Figure 5 for a standing operator. The dimensions given relate to the seat index point (SIP), as defined in ISO 5353. The outline of the space envelope does not imply the shape of the enclosure. This shape can be different than those illustrated provided that the minimum dimensions are met. The minimum operator space envelope is based on the large operator dimensions shown in Figures 1, 2 and 3 and is measured to the interior surface without visible surface deformation of the operator enclosure. 5.2  Allowable adjustments 5.2.1 Allowable adjustments to the minimum operator space envelope for particular machine applications and constraints are given in 5.2.2, 5.2.3, 5.2.4 and 5.2.5. The minimum operator space envelope requirements stated in this International Standard can also be supplemented or modified by standards for specific earth-moving machinery. 5.2.2 The operator enclosure minimum space envelope may be smaller than according to Figures 4 and 5 if the reduced operator space envelope for a particular machine application allows adequate space for operator performance and protection. Acceptable modifications for the operator enclosure space envelope include the following.
