Mobile road construction machinery - Safety - Part 1: Common requirements

1.1   This part of EN 500 specifies the common safety requirements for mobile road construction machinery ). The EN 500 series is applicable to mobile road construction machinery as listed in Annex A. When no specific standard exists, EN 500-1 applies.
It specifies common requirements for the design and construction of mobile road construction machinery in order to protect workers from accidents and health hazards which could occur during operation, loading, transport and maintenance.
Additional specific requirements for certain types of mobile road construction machinery are given in parts 2 to 4 and 6 of this standard.
This part of this standard gives safety requirements for all types of mobile road construction machinery and shall be used in conjunction with one of the parts 2 to 4 and 6. These machine-specific parts do not repeat the requirements from part 1 but add to or replace the requirements for the type of mobile road construction machinery in question.
Machine-specific requirements in parts 2 to 4 and 6 take precedence over the respective requirements of this stan-dard.
For types of mobile road construction machinery not dealt with in parts 2 to 4 and 6, EN 500-1 applies.
1.2   This European Standard deals with all significant hazards, hazardous situations and events relevant to mo-bile road construction machinery, when they are used as intended and under conditions of misuse which are rea-sonably foreseeable (see Clause 4).
This European Standard specifies the appropriate technical measures to eliminate or reduce risks arising from the significant hazards as specified in Clause 4.
1.3   This European Standard applies to machines which are manufactured after the date of publication of this European Standard by CEN.

Bewegliche Straßenbaumaschinen - Sicherheit - Teil 1: Gemeinsame Anforderungen

1.1   Dieser Teil von EN 500 beschreibt die gemeinsamen Sicherheitsanforderungen für bewegliche Straßenbaumaschinen1). Die EN 500er-Reihe gilt für bewegliche Straßenbaumaschinen, wie sie im Anhang A aufgelistet sind. Wenn keine besondere Norm vorhanden ist, gilt EN 500-1.
Sie beschreibt gemeinsame Anforderungen für die Gestaltung und Konstruktion von beweglichen Straßenbaumaschinen, um Beschäftigte vor Unfällen und Gesundheitsgefahren zu schützen, die beim Betrieb, beim Verladen, beim Transportieren und bei Wartungsarbeiten auftreten können.
Für bestimmte Arten von beweglichen Straßenbaumaschinen sind ergänzende besondere Sicherheitsanforderungen in den Teilen 2 bis 4 und 6 dieser Norm festgelegt.
Dieser Teil dieser Norm beschreibt Sicherheitsanforderungen für alle Arten von beweglichen Straßenbaumaschinen und muss zusammen mit einem der Teile 2 bis 4 und 6 angewendet werden. Diese maschinenspezifischen Teile wiederholen nicht die Anforderungen von Teil 1, sondern ergänzen bzw. ersetzen die Anforderungen für die jeweilige Art der beweglichen Straßenbaumaschine.
Die maschinenspezifischen Anforderungen in den Teilen 2 bis 4 und 6 haben Vorrang vor den entsprechenden Anforderungen in dieser Norm.
Für bewegliche Straßenbaumaschinenarten, die nicht in den Teilen 2 bis 4 und 6 der EN 500 behandelt werden, gilt EN 500-1.
1.2   Diese Norm behandelt alle signifikanten Gefährdungen, Gefährdungssituationen und Gefährdungsereignisse, die auf bewegliche Straßenbaumaschinen zutreffen, wenn sie bestimmungsgemäß verwendet werden. Die nach vernünftigem Ermessen für den Hersteller vorhersehbare Nutzung der Maschine außerhalb der bestimmungsgemäßen Verwendung ist ebenfalls berücksichtigt (siehe Abschnitt 4).
Diese Europäische Norm beschreibt die angemessenen technischen Maßnahmen, um die Risiken auszuschließen oder zu reduzieren, die von den in Abschnitt 4 spezifizierten signifikanten Gefährdungen ausgehen.

points (hooks, rings, ears) to allow slow towing and retrieval out of possible danger-zone. Their location, permissi-
ble forces, the procedure of towing as well as the maximum towing speed shall be clearly described in the instruc-
tion handbook.
5.3.2.5 Fixing of movable elements
Means shall be available to prevent moving of movable parts which could exceed the permissible transport width
during transport (e.g. hydraulic or mechanical devices).

stricted visibility exist, indirect visibility with, preferably CCTV or detecting systems, e.g. ultra-sonic warning
device, can additionally be provided.
