Earth-moving machinery - Guards and shields - Definitions and specifications (ISO 3457:1986)

This International Standard gives definitions and specifies the characteristics of different guards and shields to protect personnel from accidental hazards which may arise during operation and servicing of earth-moving machines due to:   - mechanical causes;  - thermal causes;  - chemical causes;  - electrical causes.   This International Standard is intended as a guide and covers both rubber-tyred and track-type off-highway earth-moving machinery of all sizes.  ROPS*, FOPS* and cabs are excluded from this International Standard.  * See ISO 3164.

Erdbaumaschinen - Schutzeinrichtungen - Begriffe und Anforderungen (ISO 3457:1986)

Diese Internationale Norm definiert Begriffe und beschreibt die Anforderungen für verschiedene Schutzeinrichtungen, damit sie Beschäftigte vor Unfallgefahren schützen, die während des Betriebes und bei der Wartung von Erdbaumaschinen durch mechanische, thermische, chemische, elektrische Ursachen eintreten können. Diese Internationale Norm gilt als Richtlinie für Erdbaumaschinen aller Größen, sowohl auf Rad- als auch auf Raupenfahrwerken. Diese Internationale Norm gilt nicht für ROPS1), FOPS1) und Fahrerkabinen.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of
national Standards bodies (ISO member bedies). The work of preparing International
Standards is normally carried out through ISO technical committees. Esch member
body interested in a subject for which a technical committee has been established has
the right to be represented on that committee. International organizations, govern-
mental and non-governmental, in liaison with ISO, also take part in the work.
Draft International Standards adopted by the technical committees are circulated to
the member bodies for approval before their acceptance as International Standards by
the ISO Council. They are approved in accordance with ISO procedures requiring at
least 75 % approval by the member bodies voting.
International Standard ISO 3457 was prepared by Technical Committee ISO/TC 127,
Earth-moving machinery.
This third edition cancels and replaces the second edition (ISO 3457-19791, subclauses
4.3 and 4.4 of which have been technically revised.
Users should note that all International Standards undergo revision from time to time
and that any reference made herein to any other International Standard implies its
Jatest edition, unless otherwise stated.
