An improved design has been applied to the self propelled monorail transporter, which removed the complex remote control device from the original design and used simpler, more reliable and economical mechanism of the four-bar-lever linkage clutching and braking by striking so as to realize the transporter′s clutch separating and automatic, reliable braking at any point along the orbit. In this way, the unmanned driving of the vehicle can be realized. Besides,air-cooled gasoline engine has replaced the original diesel engine, which increased the horsepower and reduced the weight and overall dimensions of the machine. The design of the T grip wheel has been optimized to prevent the transporter from skewing. The turning radius has been reduced, the original auxiliary orbit has been removed and its altitude has been cut so that the difficulty of the installation of the orbit has been reduced and the construction costs has been lowered by 40%.The results of experiment showed that the transporter could climb up the slope of 40° with a load of 500 kg, and climb down with 1000 kg and the minimum turning radius is less than 4 m. At the same time the monorail transporter worked reliably, ran smoothly and operated simply, which is perfectly suitable for mountainous transportation. 
