Abstract: The frame support carrier is a kind of transportation equipment for long-distance transportation of hydraulic supports in fully mechanized coal mining face. Its unique U-shaped frame structure can realize the whole continuous transportation of hydraulic supports in fully mechanized coal mining face without disassembly. It has the characteristics of large load capacity, flexibility, safety and efficiency, and is the core equipment for moving and reversing faces in high-yield and high-efficiency mines. The frame support truck used in the early stage of China's mines is mainly imported, which inevitably has some defects, such as high cost of equipment and spare parts, untimely arrival and lagging technical support, which seriously affects the production efficiency of coal mines. With the continuous accumulation of technical research and application experience of imported equipment, combined with the moving and reversing technology of fully mechanized coal mining face in China, many key technologies, such as high-power explosion-proof diesel engine technology, wheel reducer technology with wet brake, sprocket+ring chain open load lifting technology, mining heavy-duty solid tire pressure release technology, etc., have been tackled with difficulties, adaptability improvement and independent innovation, realizing zero barriers of related technologies, and some technologies are already in place. After more than ten years' development, the series models of the frame support truck in China have achieved full coverage of the 30-100t load range, advanced technology and stable performance, which fully meet the use requirements of coal production enterprises in China. With the shift of national coal mining strategy and the advancement of battery power technology, the future frame support truck equipment will have greater development in thin coal seam and pure electric direction.
