Description

Technical Field

[0001] The present invention is applicable to the technical field of agricultural transport equipment, and in particular to a traction-type rail transport vehicle suitable for hilly and mountainous areas with complex terrain. Background Art

[0002] my country's fruit production is geographically concentrated in hilly and mountainous areas. This terrain is naturally characterized by steep slopes and fragmented plots. This, coupled with the generally underdeveloped construction of basic transportation infrastructure such as field roads, has created a significant bottleneck restricting the development of the local fruit industry. The advent of tractor-trailers has overcome this bottleneck. These tractor-trailers are powered by electric motors and hauled by steel ropes. The cargo carrier is positioned between the tracks, enabling forward and reverse movement, as well as horizontal turns. These tractor-trailers are particularly well-suited to the steep slopes and curvatures of my country's mountainous terrain. Currently, dual-track tractor-trailers are widely used in hilly and mountainous orchards. Existing technologies primarily utilize engine-trailer-trailers and chain-type loop cableway systems. However, the single-track design of these tractor-trailers results in a higher center of gravity when loaded, which can easily cause the vehicle to tilt when encountering uneven terrain, subjecting the track system to significant torsional loads. Compared to a single-track structure, a dual-track structure with dual support points achieves a more balanced distribution of dynamic loads, significantly improving the lateral stability of the tractor and thus effectively mitigating the risk of instability in complex terrain.
