best quality 2.5 tonne anti-explosion battery locomotive manufacturers

The underground coal mine electric locomotive refers to the mining battery locomotive used in the underground coal mine. The most obvious difference between coal mines and other working scenarios of mining electric locomotives is that coal mines have different concentrations of gas, which means that the use of mining electric locomotives in coal mines has a potential explosion hazard. And other mines may appear gas only when they encounter coal measure strata.
The locomotive is applied of speed control of IGBT chopping wave type or VF type. Its main features include: smooth starting, stable operation, small dimension, short wheel base, quick and reliable braking effect by means of braking shoes; simple structure for easy maintenance and reliable locomotive operation performance. It is an ideal type for tr8nspod8tion or transfer service in medium-small mines. 

     

    Battery-powered locomotives are designed for horizontal rail transport especially in mines and enclosed spaces. They are also intended for use in potentially explosive environment with coal dust and methane in volume up to 1.5 %. They can work on slopes of rail lines up to 35‰ , with track gauge from 500 to 1060 mm, at ambient temperatures from -20°C to +40°C.

There are four common models of explosion-proof battery electric locomotives: CTY2.5, CTY5, CTY8, and CTY12. The numbers represent the tonnage of the corresponding models, and can also be customized if required. In addition, depending on the configuration, there are some detailed divisions. For example, the gauge is 600mm, 762mm, 900mm, the control methods include chopper speed regulation and frequency conversion speed regulation, and the braking methods include mechanical braking, hydraulic braking and air braking.
