It should be noted that, in the process of lifting the hydraulic support, the lifting heights of the support truck are different due to different types of the hydraulic supports, such as the middle support, the transition support, the chopping support and the like, and the lifting heights of the same type of support carried under different working conditions are also different. If the height limit of the lifting mechanism is not considered, theoretically, the absolute height of the lifting mechanism is increased, then the diameter of a chain wheel of the lifting mechanism is designed to be increased, and the lifting height is increased once, so that the lifting requirements of various hydraulic supports can be met. However, if the absolute height of the lifting mechanism is higher, the phenomenon of 'top scraping' is caused in the process of transporting the support in a low roadway of the underground coal mine, and the phenomenon of 'ground rubbing' is caused on the underground hollow pavement of the coal mine due to insufficient lifting height, so that great threat is caused to the transporting safety of the hydraulic support.
