This part gives the common safety requirements for earth-moving machinery families and is intended to be used in conjunction with one of the EN 474 parts 2 to 12. These machine specific parts (EN 474-2 to -12) do not repeat the requirements from EN 474-1:2006+A1:2009, but add or replace the requirements for the family in question.
NOTE 3 The requirements specified in this part of the standard are common to two or more families of earth- moving machinery.
Specific requirements in EN 474 parts 2 to 12 take precedence over the respective requirements of
EN 474-1:2006+A1:2009.
For multipurpose machinery the parts of the standard that cover the specific functions and applications have to be used e.g. a compact loader also used as a trencher shall use the relevant requirements of EN 474 parts 1, 3 and 10.
The standard also covers general requirements for attachments intended to be used with earth moving machine families covered in the scope.
Except for part 12 this European Standard does not deal with the electrical hazards related to the main circuits and drives of machinery when the principal source of energy is electrical.
This European Standard does not deal with towing of trailers.
This European Standard deals with all significant hazards, hazardous situations and events relevant to earth-moving machinery, when used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer (see Clause 4).

For compact machines the minimum space envelope width (dimension 920 mm in !EN ISO 3411:2007, Figure 4") may be reduced to 650 mm. The minimum space and location of the controls at the operator's station shall meet the requirements specified in EN ISO 6682:1995. 5.3.1.3 Moving parts Measures shall be taken to avoid accidental contact from the operating position with moving parts, e.g. the wheels, or tracks or working equipment and/or attachment in accordance with relevant subclauses of 5.14. 5.3.1.4 Engine exhaust The engine exhaust system shall release the exhaust gas away from the operator and the air inlet of the cab. 5.3.1.5 Instruction storage A space intended for the safekeeping of the operator’s manual and other instructions shall be provided near the operator's station. The space shall be lockable, unless the operator's station can be locked. 5.3.1.6 Sharp edges The operator's space within the operator's station, e.g. ceiling, inner walls, instrument panels and access to the operator's station shall not present any sharp edges or acute angles/corners. Radius of corners and bluntness of edges shall comply with ISO 12508:1994 to avoid sharp edges (see also 5.14.6). 5.3.2 Operator's station equipped with a cab 5.3.2.1 Climatic conditions The cab shall protect the operator against foreseeable adverse climatic conditions. Provisions shall be made to install a ventilation system, an adjustable heating system and a system for defrosting windows. For details see 5.3.2.6 to 5.3.2.8. 5.3.2.2 Pipes and hoses Pipes and hoses located inside the cab which contain fluids that are dangerous, for example because of their pressure (greater than 5 MPa), temperature (greater than 50°C) shall be guarded, see EN ISO 3457:2003, Clause 9. NOTE As far as possible pipes and hoses should be placed outside the cab. Parts or components placed between pipes or hoses and the operator, which divert e.g. a hazardous spray of fluid, can be considered as a sufficient protection device. 5.3.2.3 Primary access opening A primary access opening shall be provided. The dimensions shall comply with EN ISO 2867:2006, Figure 4 and Table 4. SIST EN 474-1:2007+A1:2009
EN 474-1:2006+A1:2009 (E) 15 5.3.2.4 Alternative opening (emergency exit) An alternative opening shall be provided on a side other than that of the primary opening. The dimensions shall comply with EN ISO 2867:2006, Clause 11. A window panel or another door is acceptable if they are easy to open or remove without the use of keys or tools. Latches may be used if they can be opened from the inside without the use of keys or tools. The break of a suitable size of glass pane is considered equivalent to an alternative opening. In such a case the necessary pane hammer, immediately accessible to the operator, shall be provided and stored in the cab. When the window panel is used as an emergency exit it shall bear an appropriate marking according to Figure 8 of EN 61310-1:1995. 5.3.2.5 Space envelope height The minimum space envelope height R1 as defined in !Figure 4 of EN ISO 3411:2007" and measured from the seat index point (SIP), as defined in EN ISO 5353:1998, shall meet the values given in Table 1. Table 1 — Space envelope height related to machine classification Machine classification Minimum space envelope height mm from the SIP Compact machines 920 All other machines 1 000
The minimum dimensions given in Table 1 are also required for machines having a front or rear window which are located (in an opened position) above the operator's seat. 5.3.2.6 Heating and ventilation system If a heating system is fitted it shall either: a) comply with !ISO/DIS 10263-4:2007", or b) have the capability of increasing the temperature of the air inside the cab and maintain a temperature of + 18°C at expected ambient temperature the machine is intended for. The minimum capacity of the heating system shall have a ∆T of 25°C (∆T of 25 K) within 30 min. The test shall run starting with the engine at working temperature as specified by the manufacturer. Measurement of the system capacity shall be made at three points. The three points shall be located in a vertical plane through the SIP and parallel to the longitudinal axis of the machine as follows (see Figure 3): 1) at filament position centre-point as defined in ISO 5006:2006; 2) at the SIP as defined in EN ISO 5353:1998; 3) 100 mm above floor plate and 600 mm in front of SIP.
