10、ry Excavators Operators controls”, published by the International Organization for Standardization (ISO). ISO4557 was produced as a result of international discussion in which the United Kingdom took an active part. Terminology and conventions. The text of the International Standard has been approve
11、d 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 standard, they
12、 should be read as “British Standard”. A British Standard does not purport to include all the necessary provisions of a contract. Users of British Standards are responsible for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations. Cr

16、s on excavators as they relate to the operator and his position on the machine. 2 Field of application This International Standard applies to excavators as defined in ISO6165 and is intended as a guide when designing operator controls on these machines. Cable operated excavators are excluded. The ra

19、ll be located as specified in5.1, which takes seat adjustment into account. 5 Location of controls 5.1 The controls for machine operation and travel listed in Table 1 shall be located with their neutral position and, if possible, all other positions in the zones of comfort. All other positions that
20、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 that all positions they may occupy are within the zone of reach. The combining of controls is permissible. 5.2 The controls should be o
21、f reliable design and construction and arranged so that they can be operated with ease from the operators seat within the force limits ofTable 2. 5.3 Controls, control linkages, hoses, tubes and connections shall be arranged in such a manner that they are unlikely to be damaged by external foreseeab
22、le 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, handles, knobs, the operators body and other machine parts shall be sufficient to allow operation without unintentional actuati
23、on of adjacent controls. 5.5 The surface of frequently-used pedals shall be fitted with skid-resistant type material with, where practical, raised edges to reduce the possibility of the foot slipping off the pedal. The pedals may be adjustable. 5.6 The overlapping of foot pedals is permissible. Mach

28、 forces The maximum forces inTable 2 shall not be exceeded for normal operation. However these forces may be exceeded on a control for an emergency. The direction of force shall be referenced to the operators position while operating the control. Table 2 Control forces 1) Symbols, in accordance with
