The development of trackless transport vehicles can be divided into the following important stages:
Origin and early development: The concept of trackless transport vehicles can be traced back to 1962, when the first underground diesel engine-driven trackless loader was introduced. This equipment began to be used in countries with advanced coal mining technology and was gradually promoted and used underground in some coal mines.
Technological progress and application expansion: With the development of technology, trackless transport vehicles are not limited to diesel engine drive, but also developed versions driven by cable traction motors. These devices are mainly used for the transportation of rocks (ores), stones and materials, suitable for medium and short-distance transport loader and long-distance transport underground mining vehicles (load capacity can reach more than 45 tons).
Application at home and abroad: Although China has made some progress in the application of trackless transport equipment, there is still a gap compared with the world's advanced countries. In the future, it is necessary to further develop and improve explosion-proof diesel engine rubber-wheeled vehicles, and increase the research and development of battery traction power vehicles with low air pollution in the tunnel and high power.
Technological innovation and market trends: In recent years, the application of trackless transport equipment in coal mines has gradually increased. With the need for high-yield and high-efficiency modern mine construction, the application of trackless transport equipment will receive more and more attention.
