3 Terms and definitions
For the purposes of this document, the terms and definitions given in GB/T 3367 (all parts), as well as the following, apply.
3.1
industrial and mining diesel locomotive
A diesel locomotive used for transportation in factories and mines.
[Source: GB/T 3367.1-2018, 2.1.7]
3.2
hybrid diesel locomotive
A locomotive that uses an internal combustion engine as the power source combined with other power sources (such as power batteries).
3.3
power battery system
A complete energy storage device consisting of one or more power battery units connected in series and/or parallel, providing energy for the locomotive traction system.
4 Types
Industrial and mining diesel locomotives (hereinafter referred to as "locomotives") are classified by operating site into:
a) Surface locomotives;
b) Underground mining locomotives.
5 Basic parameters
5.1 The basic parameters for surface locomotives should preferably be selected from the values specified in Table 1.
5.2 The basic parameters for underground mining locomotives should preferably be selected from the values specified in Table 2.
6 Technical requirements
6.1 Environmental operating conditions
6.1.1 The environmental operating conditions for locomotives are as follows:
a) Ambient temperature: −25 °C to 40 °C;
b) Electrical equipment shall be capable of normal operation when the relative humidity does not exceed 50 % at a maximum temperature of 40 °C. Higher relative humidity may be permitted at lower temperatures, e.g., 90 % at 20 °C;
c) Wind speed shall not exceed 12.5 m/s;
d) Altitude shall not exceed 700 m.
Note: When the operating environmental conditions exceed the above ranges, they shall be determined by agreement between the user and the manufacturer.
