The mode of carrying out material transportation in mountain area usually has road transport and cableway transportation etc.. Facilities such as cableways are erected in cableway transportation, and the cableway transportation cannot leave roads and transportation vehicles. However, in many places in mountain areas, roads are not available at all or the road conditions are poor, so that road repair is required for transportation, and the livestock power of transportation vehicles or mules and horses is required. Two problems to be faced in the mountain road construction are, firstly, the problem of ecological environment protection, namely, the original water, soil and vegetation state is kept as much as possible. And secondly, the construction channel belongs to temporary facilities, and the road grade is low, so that the cross-country performance of the transport vehicle walking on the construction channel is good.

It is known that tracked vehicles, due to their special running gear, have very good off-road performance, which requires considerably less traffic than wheeled vehicles. Many construction vehicles therefore employ tracked chassis. The tracked vehicles generally have the capability of climbing, crossing ridges and crossing ditches, but the actual performance is also related to factors such as the power configuration of the tracked vehicles, the sizes and the specific structures of the tracked vehicles. The traffic capacity of the miniature crawler transport vehicle is positioned on a road similar to a mule horse. According to the analysis, the road width of the miniature crawler capable of passing through the road is determined to be not less than 1.2 meters. The transport capacity of miniature tracked vehicle should surpass mule horse's transport capacity greatly, when walking on the mountain road, should control the vehicle with the remote control mode to guarantee operating personnel's safety.

Ordinary wheeled chassis transport vechicle can produce peak phenomenon even topples when going on abominable ground, not only goes very unstably and can also cause life safety accident, and serious can produce and take off or damage the track moreover.
