Highland backhole loader

The invention discloses a highland backhole loader. The highland backhole loader comprises a frame (8) serving as a main body, a loading working device (13), an excavation working device (1), a cab assembly (3), a power system (9), a machine cover coverage part (10), a drive system (11), a working hydraulic system (2), a parking brake system (5), a running brake system (7), a steering hydraulic system (4), an air conditioning system (12) and an electrical applicable system (6) and further comprises a life supporting system (14) capable of meeting the oxygen demand of a driver in a highland, an adjustable independent heat dissipation system (15) capable of controlling the rotating speed of a fan according to the temperature of a radiator and a low-temperature heating system (16) capable of ensuring -40 DEG C smooth starting of the whole loader. The environmental adaptation of the backhole loader is greatly improved, and the highland backhole loader can especially adapt to highland high-and-cold, oxygen-poor and strong-ultraviolet severe environments and the like.
