10、wler tractors and crawler loaders Operators controls”, published by the International Organization for Standardization (ISO). ISO7095 was produced as a result of international discussion in which the UK took an active part. Terminology and conventions. The text of the International Standard has been
11、 approved as suitable for publication as a British Standard without deviation. Some terminology and certain conventions are not identical with those used in British Standards; attention is especially drawn to the following. Wherever the words “International Standard” appear, referring to this standa
12、rd, they should be read as “British Standard”. There is no corresponding British Standard to ISO6405, but when ISO6405 is published, it is expected that a corresponding British Standard will also be published. A British Standard does not purport to include all the necessary provisions of a contract.
13、 Users of British Standards are responsible for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations.

17、 International Standard applies to crawler tractors and crawler loaders as defined in ISO6165 and is intended as a guide when designing operator controls on these machines. The range of sizes of operators considered in this document is that established in ISO3411. 3 References ISO 3411, Earth-moving

19、ound the operator for operator enclosures (cabs, ROPS, FOPS) and the clearance between the operator enclosure and controls are defined in ISO3411. 4.2 The operators controls shall be located as specified in5.1 which takes seat adjustment into account. 5 Location of controls 5.1 The controls listed i
20、n Table 1 shall be located with their neutral position and, if possible, all other positions in the zones of comfort. All positions that they may occupy shall be at least within the zone of reach. See ISO6682. Table 1 Controls All controls frequently used and not specified above shall be located so
21、that all positions they may occupy are within the zone of reach. The combining of controls is permissible. 5.2 The controls should be of reliable design and construction and so arranged that they can be operated from the operators seat within the force limits of Table 2. 5.3 Controls, control linkag
22、es, hoses and tubes, and connections shall be arranged in such a manner that they are unlikely to be damaged by external foreseeable forces (i.e.used as a step; maximum hand or foot force exerted) and are easily accessible for inspection. 5.4 The distance between control levers, adjacent foot pedals
23、, handles, knobs and other machine parts shall be sufficient to allow operation without unintentional actuation of adjacent controls. 5.5 The surface of frequently used pedals shall be fitted with skid-resistant type material. Where practical and necessary, the pedals shall have raised edges to redu
24、ce the possibility of the foot slipping off the pedal. The pedals may be adjustable. 5.6 The overlapping of foot pedals is permissible to provide for independent and simultaneous control application. 5.7 Machine motion controls shall generally be left-hand operated and tool controls shall generally
25、be right-hand operated. 6 Movement of controls 6.1 The movement of tool controls, in relation to their neutral position, shall be in the same general direction as the movement they control, unless customary usage or combining of controls dictates otherwise. 6.2 Power for movement of the tools shall
26、continue for as long as an action is exerted by the operator on these controls and shall be discontinued automatically as soon as this action ceases. Controls which are retained in a power position but are equipped with an automatic release are acceptable. 6.3 A diagram 1)of the controls showing the
27、ir location, function and direction of operation except those whose function is obvious, i.e.brake pedal, accelerator, shall be placed in the operator area where it is easily visible to the operator.

However, these forces may be exceeded on a control for an emergency. The direction of the
29、force shall be referenced to the operators position while operating the control.
