19、281:2005ii ENISO21281:2005 iiiForeword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interes
20、ted in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical C
21、ommission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the tech
22、nical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO
23、shall not be held responsible for identifying any or all such patent rights. ISO 21281 was prepared by the European Committee for Standardization (CEN) Technical Committee CEN/TC 150, Industrial trucks Safety, in collaboration with Technical Committee ISO/TC 110, Industrial trucks, Subcommittee SC 2
24、, Safety of powered industrial trucks, in accordance with the Agreement on technical cooperation between ISO and CEN (Vienna Agreement). ENISO21281:2005iv Introduction The use of industrial trucks differs essentially from that of road vehicles, which are mainly driven in the forward direction. Indus
25、trial trucks, especially forklift trucks as working machines, have a high share of movement in the backward direction, frequent change of direction of movement, and relatively low speed. They often are used with attachments. According to the specific requirements, industrial trucks are equipped with
26、 optimized controls. In certain types of driving units (e.g. hydrostatic, electrical), the driving mechanism also acts as a brake. This International Standard covers the most frequently used pedal layouts. Other pedal arrangements for travelling are possible provided that the new ergonomic results a
27、re considered.

34、may, where applicable, control the transmission ratio and/or the direction of travel. 3.6 direction-control pedal pedal controlling the direction of travel only 4 Requirements The pedal layout and construction shall ensure a comfortable position for the operator, moderate operating efforts and a sma
35、ll number of operations, taking ergonomic principles into consideration. If a service brake pedal is fitted, it shall be depressed to apply the brakes and shall be capable of being activated by the operators right foot. The service brake may also consist of two adjacent pedals capable of allowing br
36、aking of the left and right wheels separately or both together. If a combined brake pedal for inching and braking is used, it shall be capable of being operated with the left foot or both feet. Operation of the service brake pedal(s) shall not be hindered by the simultaneous use of other controls. I
37、f service braking is effected by means other than a brake pedal, the area normally occupied by the brake pedal shall remain free. If a clutch pedal is fitted, it shall be depressed to declutch. The final movement may also, when the facility is provided, apply the service brake. It shall be capable o
38、f being operated by the operators left foot. If an inching pedal is fitted, it shall be depressed to disengage the transmission and apply the service brake. It shall be capable of being operated by the operators left foot. If there is no separate means of applying the service brake, the inching peda
39、l shall be a single pedal capable of being operated equally by either foot. If an accelerator pedal or pedals is/are fitted, depression of the pedal shall increase the speed, but may also reduce the speed when the truck is in motion and reverse traction is selected. Release of the pedal may provide
40、retardation of travel speed. If a hand-operated direction control and an accelerator pedal are fitted (see Table 1, Type I), the accelerator pedal shall be located to the right of the brake pedal. If foot-operated direction control is fitted, the direction of travel may be selected by actuating eith
41、er a direction change pedal or one or two pedals that select the direction of travel and also perform the function of the accelerator pedal (see Table 1, types II and III). 5 Identification Pedal function shall be clearly indicated in the operators manual. Where the travel direction is controlled by
42、 pedal(s), its/their function(s) shall also be clearly and durably marked on the truck. This marking may be direction arrow(s) on the relevant pedal(s).

43、ned and constructed in such a way that their strength is compatible with the forces to which they are normally subjected. The release of all pedals shall ensure their automatic return to their original positions. The surface of all pedals shall be slip resistant. 7 Pedal layouts The pedal layouts in
44、 common use to date, shown in Table 1, comply with the requirements of this International Standard. Other pedal arrangements resulting from technical progress or new operating conditions are admissible only if they comply with the general requirements of this International Standard and allow an equi
