Mine car transport coal mines, ore and waste rock and other bulk materials handling vehicles narrow gauge railway 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. Harvesters basic components: the "Coal Mine Safety Regulations" provides that: tilting roadway transport connection Qinghai curved rail side dump mine car, the connection between the tub, between the tub and the rope must use a connection can not be off on their own devices. Thus, the connector plug the tub must have anti-shedding devices. Years of use showed that the anti-fall device lock ring style better.
