Abstract: In order to meet transportation requirement of low-height crawlway of Shendong Group, the paper proposed a design scheme of WC5 low-height explosion-proof diesel trackless rubber-tyred vehicle. The low-height vehicle was designed with mature design technology of WC5 explosion-proof diesel trackless rubber-tyred vehicle. Its part of front stand higher than regulation height was reformed combining with characteristics of driving in crawlway, back carriage was redesigned and safety design was also added to the low-height vehicle. The practice proved that the low-height vehicle decreases labor intensity of underground workers and improves work efficiency, safety and comfortableness.
