The present invention provides a crawler type climbing chair. The structural design of the ladder body is mainly composed of a seat assembly, a track assembly and a lifting mechanism； the seat assembly mainly has a seating area, and a foot pedal is disposed at a lower end of the seat area； and the track assembly is disposed at a rear end of the seat assembly, and is provided with a crawler device mainly on both sides of the seat, and is installed in an inclined state. The track assembly is provided with a transmission shaft at the bottom, and the uppermost ends of the track are provided with a wheel, so that a track is arranged between the transmission wheel and the wheel, and the double track is driven through the transmission wheel. And a lifting mechanism is disposed at a rear end of the seat assembly seating area, the lifting mechanism is provided with two telescopic rods, and a rear supporting wheel is mounted on the lower end of the telescopic rod； in addition, the seat assembly and the lifting mechanism The bottom of the system is provided with a number of sensors； thus, through the above structure, the ladder car system is coordinated by the crawler belt, the lifting mechanism and the sensor, so that the ladder car body can maintain a stable ride regardless of climbing or descending the stairs. angle Moreover, an auxiliary wheel control rod is arranged at the drive shafts on both sides of the seat assembly, and a steering assist wheel is arranged at the lower end thereof, and the user can control the steering assist by operating the auxiliary wheel control rod before or after pulling. The wheel moves up and down, so when the ladder car body wants to turn, it can control the one-side steering auxiliary wheel to descend, so that the steering auxiliary wheel supports the side track to leave the ground, and the ladder car body will face the ground with the track Rotate, according to the ladder car bodyThe condition of the rotation.本創作係提供一種履帶型爬梯椅，其結構設計上，該爬梯車本
