Track-laying industrial locomotive, hereinafter referred to as "locomotive", mainly suitable for transportation tunnels in metal mines or low-gas full-pressure ventilation coal mines for hauling ore cars, passenger cars, and materials. This track-laying locomotive features direct current power, simple structure for easy maintenance, and low comprehensive transportation costs.

The structural composition of overhead line track traction locomotives includes the walking structure, electrical principle, suspension, and principles such as gear control and braking control.

The electric tricycle's walking mechanism includes wheels, reduction box, cone gears, flat gears, wheel shaft, and bearing housing. The electrical principle of the electric tricycle includes DC motor, controller, series and parallel connections, pantograph, resistor, as well as electric horn and lights. The suspension of the electric tricycle includes shock-absorbing springs, suspension balance of the DC motor, and braking effect. In summary, the mining electric tricycle is a complex structure and is still a relatively ideal and reliable equipment for ore mine rail transportation as of now.

Motor car execution standard: MT/T1046-2008 Technical Conditions for Mining Narrow-Gauge Trolley Trains.
