8t battery electric locomotive have two types: safety model, explosion-proof model.
8t 110V and 8t 132V electric locomotive adopt one stage gear transmission, It‘s the first generation with advantages of lower bar centre, stable.
8t 140V electric locomotive adopts advanced chopper speed regulating and battery series-parallel connection step speed regulating, wimble-gear and regular-gear two stage gear transmission. With advantages of high volume of battery, heavy traction, thickness armor plate body, high resistance to strike etc.
It based on 8t 140V step-less speed regulating, 10th step speed regulating.
The implication of the symbol:
X-Battery
K-For underground mining pit
G-For engineering
KBT-Explosion-proof special type for mine
A-Symbolizing safety type
N-Normal type
C-For with wing plates being used to match with bottom or profile unloading type wagon.
Others alpha bits symbolize, adhesive weight, rail gauge, voltage and design serial number.
The Operating Environment:
For special explosion proof battery powered type electric locomotive.
1. The surrounding air temperature: -20±40℃
2. In most moist month, the average max, relative humidity is 95% (in the same month the lowest temperature is not higher than 25℃)
3. The site for coal mine special explosion-proof battery powered electric locomotive must be in according with the stipulations of 《coal mineral safety rule》
XK8-6/144-KBT Explosion-proof Battery Electric Locomotive
It’s adapt to the ambient condition where gas and coal exist , such as wind draw-out tunnel ,wind draw-out tunnel ,and not high enough to use trolley wire electric locomotive ,to haul mineral ,equipments or other locomotive.
Advantages:
1. Single control available
2. Resistor speed regulating
3. Hand-wheel braking and resistor braking
4. Adopt V rubber spring to bear shock and punch from 3 directions longitude, latitude and uprightness.
5. With advantages of super hauling, speedy, large loading capacity etc.
Composed by machinery part and electrical part:
1. Machinery parts include frame, running gear, double ceiling, chair, buffer, sands sprinkle, cover plank, buffer etc.
2. Electrical part include a major circuit composed by two sets of battery, cab control, resistor box, silicon rectifiers, two sets of traction motor, and a light circuit composed by battery, light and DC transformer.

Note:
1. Locomotive without note is single cab type, in overall dimensions of locomotives in which the wing-plate width not is included.
2. The max tractive force is determined by adhesive coefficient μ=0.25 between the wheel and rail. The max tractive force may be available only in short time starting. |
