Earth-moving machinery - Access systems (ISO 2867:1994)
This International Standard specifies criteria for access systems - steps, ladders, walkways, platforms, grab rails (handrails), grab handles, guardrails and enclosure entrance and exit openings - as they relate to aiding the operator and servicemen in performing their functions on the machinery. It applies to access systems to the operator's station and to service points o earth-moving machinery as defined in ISO 6165 while the machinery is parked in accordance with manufacturer's instructions.
Erdbaumaschinen - Zugänge (ISO 2867:1994)
Diese Internationale Norm beschreibt die Kriterien für Zugangssysteme, Stufen, Aufstiege, Laufstege, Standflächen, Haltestangen (Handläufe), Haltegriffe, Geländer und Ein- und Ausstiegöffnungen von geschlossenen Rahmen, so wie diese Einfluß auf die Sicherheit von Maschinenführern und Wartungspersonal bei der Ausübung ihrer Tätigkeit auf der Maschine haben. Sie gilt für Zugangssysteme zu Fahrerplätzen und Wartungsstellen von Erdbaumaschinen, wie sie in ISO 6165 definiert sind, bei Stillstand der Maschine, wie vom Hersteller festgelegt.

Foreword
IS0 (the International Organization for Standardization) is a worldwide
federation of national standards bodies (IS0 member bodies). The work
of preparing International Standards is normally carried out through IS0
technical committees. Each 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, governmental
and non-governmental, in liaison with ISO, also take part in the work. IS0
collaborates closely with the International Electrotechnical Commission
(IEC) on all matters of electrotechnical standardization.
Draft International Standards adopted by the technical 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.
International Standard IS0 2867 was prepared by Technical Committee
lSO/TC 127, Earth-moving machinery, Subcommittee SC 2, Safety re-
quirements and human factors.
This fifth edition cancels and replaces the fourth edition (IS0 2867:1989),
which has been technically revised.
Annex A of this International Standard is for information only.
