Introduction

This European Standard is a type C standard as stated in EN 1070

The machinery concerned and the extent to which hazards, hazardous situations and events are covered are indicated in the scope of this document

The standard takes into account the current state of the art and technical facilities to use in order to exclude or prevent, as far as possible, hazards when rail locomotives are used underground

When compiling this standard it has been assumed that:

 components are:

a) designed in accordance with good engineering practice, taking account of expected shocks and vibrations and calculation codes, including all failure modes;

b) of sound mechanical and electrical construction;

c) made of materials with adequate strength and of suitable quality; and

d) free of defects

e) harmful materials, such as asbestos are not used;

f) components are kept in good repair and working order, so that the required dimensions remain fulfilled despite wear;

g) negotiations have taken place between the manufacturer or authorised representative, purchaser and/or user (e.g for fire resistant fluids, safety equipment and load restraining devices)

Trang 7

1 Scope

This European standard specifies the safety requirements and tests for rail locomotives for use in underground mining (i.e mine locomotives) and other underground workings (e.g tunnelling locomotives)

1.1 This European standard deals with the technical requirements to minimise the hazards listed in clause 4

which can arise during the commissioning, the operation and the maintenance of locomotives when carried out in accordance with the specifications given by the manufacturer or his authorised representative

1.2 This European standard does not address the special hazards associated with the rack drive of rack

and pinion locomotives

1.3 This European standard does not deal with radiation and vibration It does not address remote control

locomotives or operation in potentially explosive atmospheres Hazards due to noise are excluded from this standard, but a separate standard is in preparation where hazards due to noise will be addressed

1.4 This European standard applies to locomotives which are manufactured after the date of issue of this

standard

Locomotives shall have facilities for stowing any safety equipment (see also introduction, on negotiations)

Trang 14

5.1.6 For unintentional contact the temperature of hot surfaces inside of the locomotive are based on annex

B of EN 13202:2000 for 0,5 s contact time For the parts that require handling during maintenance the temperature of the touchable surface shall be in accordance with EN 563 for 5 s contact time Where this limit cannot be achieved, see 7.1.3

Trang 15

sufficiently hot to reach 80 % of the flashpoint of the hydraulic fluid for which the system has been designed

b) Hydraulic lines shall be shrouded to prevent flammable fluid under pressure being ejected from a leak or

a burst onto a hot surface as defined in paragraph a) above, or outside the profile of the locomotive

in such a way that any overflow or escape of hydraulic fluid is prevented under foreseeable operating conditions, including derailment

NOTE Where hose reinforced with steel wire is used consideration needs to be given to fatigue aspects

Hydraulic hoses containing fluid with a pressure exceeding 5 MPa (50 bar) and/or having a temperature exceeding 50 °C and located within 1 m of the driver or operator shall be guarded, see 5.1.1 and 5.1.2 Parts

or components can be considered as guards

5.5.2.4 Cables shall be installed so that mechanical vibration does not cause their insulation to be worn away (e.g by rubbing or chaffing) or the enclosed conductors to fail by flexing fatigue

NOTE The use of screen cable in conjunction with leakage to frame monitoring allows the advanced warning of insulation failure which may result in short circuit of the power conductors

5.5.3 Battery-powered locomotives
