19、nditions, and counteract adverse effects on human health and performance. Good ergonomic design therefore exerts a favourable influence on the whole work system, and on the reliability of the human being within it. In this Technical Report the term ergonomics refers to a multidisciplinary field of s
20、cience and its application. Applying ergonomics to the design of operators station and/or workplaces considering the elements of the work system ensures that human capabilities, skills, limitations and needs are taken into account. This Technical Report deals with common aspects for the ergonomics d
21、esign principles of mobile machinery. This Technical Report contains different types of information to be considered and used when designing the ergonomics aspects of a mobile machinery. Some clauses provide general guidance to be considered in the design of mobile machinery. Other clauses include m
22、ore specific design guidance and requirements relevant to current technology. PD CEN/TR 614-3:2010CEN/TR 614-3:2010 (E) 6 1 Scope This Technical Report establishes the ergonomic principles to be followed during the design process of mobile machinery with special emphasis on the aspects in which mobi
23、le machinery differs from static machinery. The ergonomic design principles given in this Technical Report apply to either or both seated and standing positions. This Technical Report is applicable for the design of mobile (self-propelled and towable) machines in order to ensure ergonomic working co
24、nditions for the operator. This Technical Report applies only to driving and operating mobile machinery and not to performing other tasks (e.g. sorters on a potato harvesting machine). Pedestrian-controlled and handheld machinery are not included. This Technical Report also applies to vehicle-mounte
25、d machinery when observing their functional properties e.g. mobile cranes. Installing, cleaning, and repairing of mobile machinery is not included. Basic concepts and general ergonomic principles for the design of machinery are dealt with in prEN ISO 12100 and EN 614-1 and EN 614-2. NOTE 1 EN 614-1
26、provides a framework for incorporating ergonomics principles in the design process. This framework helps designers to perform ergonomics analyses and design actions at the appropriate stages of the design process. NOTE 2 EN 614-2 provides principles of the design of the work tasks in interaction wit
27、h machinery design. This framework helps designers to focus on the work task design and on the optimal allocation of work tasks between the operator and the machine. 2 Terms and definitions For the purposes of this Technical Report, the definitions given in EN 614-1, prEN ISO 12100 and the following

NOTE 2 The SIP is fixed with respect to the machine and does not move with the seat through its adjustment and/or oscillation range.

35、and biomechanics Special consideration needs to be given to: dimensioning of the operators work station; safety distances; dimensions for access; manual handling of component parts during assembly and disassembly (e.g. by marking the mass of the main parts). Information on anthropometrical aspects o
36、f the European population is given in EN 547-1 to EN 547-3 and EN ISO 14738. Biomechanical aspects are covered by EN 1005-1 to EN 1005-5. For safety distances, consider EN ISO 13857. 3.3 Ergonomic design principles concerning work tasks The general ergonomics principles for work task design set out
37、in EN 614-2 apply also for mobile machinery. 3.4 Accessible design for people with special requirements Where it is required, the designer should take account of people with special requirements and apply ergonomic principles to accessible design and assistive technology in order to enable the use o
38、f machinery by people with special requirements. NOTE Special needs includes sensory abilities like vision, tactile and acoustic input, physical abilities like dexterity, manipulation, movement, voice, strength and endurance, cognitive abilities like intellect, memory, language and literacy and alle
39、rgies like contact allergy and respiratory allergy. For further information see CEN/CENELEC Guide 6 and ISO/TR 22411. 4 Design of workplaces 4.1 General It is advisable that the operators station or workplace is designed, constructed and/or equipped to ensure that the operator has good operating con
40、ditions and is protected against foreseeable ergonomics hazards (for instance: temperature, air flow and humidity, noise and vibration, inadequate visibility, mental overload). PD CEN/TR 614-3:2010CEN/TR 614-3:2010 (E) 9 For most mobile machinery the sitting working position is the preferred work po
41、sition for the operator during operation as it is the most stable working position. For some mobile machines a standing work position may be required for work tasks, e.g. when the operator has to leave the machine frequently. 4.2 Workspace 4.2.1 General Consideration of the operators body dimensions
42、 (including clothing and helmet where appropriate) and task demands is a precondition in designing the operators workspace. Sufficient space for movements of the head, trunk, arms and legs is necessary in order to control the mobile machinery. Make sure that the operator is able from either a sittin
43、g or standing position to move his arms freely and to turn the upper body in an obstacle free space. For minimum operator space envelope in earth moving machines, see EN ISO 3411:2007, Clause 5. 4.2.2 Leg space The following requirements concerning leg space are essential: foot and leg space for the
44、 operating position; foot and leg space to access the operating position. NOTE The preferable location for foot-operated controls for a seated operator of earth moving machines within the “zone of comfort“ is given in EN ISO 6682. 4.2.3 Work space height considerations for seated positions The minim
45、um distance between the SIP (see 2.6) and the head guard or cabin roof can be defined according to EN ISO 3411:2007, Clause 5. 4.2.4 Work space height considerations for standing positions When operating a mobile machine in standing position it is important that the work space height ensures enough
46、space between the roof and the operator and that the space is suitable for tasks requiring good visibility. NOTE The minimum space envelope for a standing operator can be determined according to EN ISO 3411:2007, 5.1. 4.2.5 Arm space and reach envelopes The minimum space and reach envelope for the a
47、rms (to meet the “zone of comfort“) are given in EN ISO 6682. When reversing mobile machinery with a non-turning seat provide sufficient space for placing the non-steering arm behind the backrest. 4.2.6 Field of vision to displays and control actuators While designing horizontal monitoring area take
48、 into account the field of vision and the necessary movements of eye, head and body. The information about optimal and necessary horizontal and vertical fields of vision can be found in EN 894-2. See also Clause 8 of this Technical Report. PD CEN/TR 614-3:2010CEN/TR 614-3:2010 (E) 10 For maximum field of vision, see EN ISO 14738. 4.3 Seated operator 4.3.1 Seat design and adjustment Seats need to be designed with due regard to the nature of operation of the machinery.
