In addition, because of the limitation of the manual turnout structure, the position of the swing rail can only be simply aligned but can not be locked, so that the problem that the swing rail and the end rail are misplaced easily when a single rail is lifted and moved through is caused, and further, the driving friction wheel of the locomotive is damaged, and even the locomotive derailment safety accident occurs. The action of the simple pneumatic turnout swing rail is controlled by a double-acting air cylinder, and the simple pneumatic turnout swing rail does not realize accurate positioning like a common manual turnout and does not have limit locking after the simple pneumatic turnout swing rail acts in place.
For both types of switches, there are no stops on the switch swing rails and the two branch end rails. If the swing rail is not in place, the locomotive driving friction wheel is damaged when the monorail crane locomotive passes through the turnout, and even accidents such as locomotive derailment and the like are likely to occur. In addition, for the two types of turnouts, the corresponding safety marks and humanized design are lacked, so that the recognition and deceleration before the driver of the monorail crane passes the turnout are not facilitated, and the probability of accident of the monorail crane is further increased.
