Tramcar narrow-gauge railway transport vehicle mines transport coal, ore and waste rock and other bulk materials Henan curved rail side dump mine car, generally required traction locomotive or winch. Harvesters basic components: the two ends of the frame assembly buffer. Buffer directly to withstand traction and impact of parts, in the past most of the coil spring to absorb the impact of Hebei curved rail side dump mine car, in recent years, it is also useful rubber spring. Tramcar narrow-gauge railway transport vehicle mines transport coal, ore and waste rock and other bulk materials, are generally required traction locomotive or winch. Coal narrow gauge mine car safety: homemade materials, vehicles, flatbed, shelf trucks, special dedicated vehicles meet its structure and tensile strength testing must be made to ensure its safety and reliability.
