[0003] The existing crawler support transporter has the following shortcomings: First, once the safety performance of the diesel internal combustion engine fails, the diesel internal combustion engine with failed safety performance is an effective ignition tool for coal dust explosions that may occur at the work site, thus posing a major safety hazard; Second, the advance support range of the comprehensive mining working face is prone to bottom bulging and cement accumulation, which increases the operating risk of the crawler support transporter. In severe cases, special personnel need to be arranged to clean and level the tunnel floor, resulting in increased production costs and affecting the transportation speed; Third, when the tunnel height is insufficient, the crawler support transporter cannot operate, which increases the amount of manual bottom lifting and production costs, and limits the use of gantry supports in the advance support range of medium and thick coal seams. Utility model content:
