National foreword

This British Standard has been prepared by Subcommittee B/513/1 and is the English language version of EN 500-2:1995 Mobile road construction machinery Safety Part 2: Specific requirements for road-milling machines, published by the European Committee for Standardization (CEN). It is one of a number of British Standards implementing European Standards on machinery safety matters, in the development of which the United Kingdom has played an active part.This British Standard covers the essential safety requirements in the Machinery Directive (89/392/EEC) and the Amending Directive (91/368/EEC).

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.

0 IntroductionThis Part of EN 500 contains additional requirements to EN 500-1:1995 Common requirements. The clauses of this standard have the same numbering as those of EN 500-1:1995.

1 ScopeThis Part of EN 500 specifies the safety requirements for road-milling machines as defined in clause 3 and deals with the significant hazards pertinent to road-milling machines, when used as intended and in conditions foreseen by the manufacturer.

2 Normative referencesThis European Standard incorporates by dated or undated references, provisions from other publications. These normative references are cited at the appropriate places in the text and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision. For undated references the latest edition of the publication referred to applies.EN 500-1:1995, Mobile road construction machinery Safety Part 1: Common requirements. prEN 953:1992, Safety of machinery General requirements for the design and construction of guards (fixed, movable).

3 DefinitionsFor the purposes of this standard the following definitions apply.

3.1 road-milling machines

mobile machines used for removing material from paved surfaces

3.2 milling equipment (cutter drum)

power-driven cylindrical bodies, on which surface the milling tools are fitted. The cutter drums rotate during the cutting operation

5.9.1 Milling equipment

5.9.1.1 General

It shall be possible to stop the milling equipment, even while the power unit (engine) is running. The milling equipment shall be safeguarded to prevent accidental physical contact and to retain debris and parts possibly ejected.Guards shall comply with clauses 6 and 7 of prEN 953:1992.Guards and flaps shall remain permanently attached, even when they are opened.

5.9.1.2 Rear guards

The dimension B may be exceeded for a short time if necessary, with regard to proper material discharge. For this purpose a built-in warning system shall be provided. This warning system shall consist of yellow blinking lamps visible from all directions within the danger area. The lamps shall automatically be activated as long as the dimension B is exceeded while the power-unit is running.

5.9.1.3 Side guards

Power-operated side panels of the drum guards, intended to be controlled during operation of the machine, shall comply with the following design criteria:

the control device (handle) shall not lock in any position except in neutral (hold-to-move control); the control handle shall be fitted away from danger areas; a yellow flashing light shall be fitted within the danger areas and shall be activated whenever the control devices (handles) are operated, and the power-operated side panels shall automatically return to their normal (pre-set) position when the control device (handle) is released.

5.9.2 Footguards

Wheels and tracks in the vicinity of the operators station, and/or in the access areas, shall be provided with footguards. Guards shall comply with clauses 6 and 7 of prEN 953:1992.

5.9.3 Lowering the milling drum

The machines shall be provided with a safety device preventing any unintentional machine movements when lowering the drum to the cutting mode.

5.9.4 Elevating devices

Elevating devices on the machines shall be provided with a mechanical locking device to ensure safe elevation when maintenance is to be performed under the elevated devices.

NOTE The mechanical locking device can be integrated with the elevating devices or can be a permanently attached separate unit. The instruction handbook should include instruction on the use of the mechanical locking device.

5.10 Precautions against hazards caused by non-electric energy sources

See EN 500-1:1995.

5.11 Fire protection

See EN 500-1:1995.

5.12 Hazards due to extreme temperatures

See EN 500-1:1995.

5.13 Signal devices and warning signs

A clearly visible and permanent warning sign shall be applied on both sides of the movable guards, or on the protective devices, located around the cutter drum. The marking shall have the form of a warning triangle in accordance with Figure 2. The sides of the triangle shall measure at least 60 mm.

6 Instruction handbookSee EN 500-1:1995.

7 MarkingSee EN 500-1:1995.
