The invention relates to a hoisting system suitable for a long and narrow tunnel anchor hole with multiple dip angles, and belongs to the technical field of bridge construction. The lifting system comprises a suspension bracket and a lifting appliance, the suspension bracket is fixed to the top end in an anchor hole, and the lower end of the suspension bracket is provided with a limiting device for fixing a bearing cable and a riding wheel for supporting a traction cable; the lifting appliance is of a semi-surrounding structure with an opening in the upper portion, the traction rope is connected to the lifting appliance, and when the lifting appliance passes through the hanging frame, the idler wheels arranged at the upper end of the lifting appliance can pass through a limiting device arranged on the hanging frame. The bearing cable penetrates through the limiting device of the suspension frame and is pressed and fixed by the limiting device, the riding wheel can support the traction cable, the lifting appliance is of a semi-surrounding structure with an opening in the upper portion, the traction cable is connected to the lifting appliance, and when the lifting appliance passes through the suspension frame, the idler wheel arranged at the upper end of the lifting appliance can pass through the limiting device arranged on the suspension frame, so that the lifting appliance passes through the suspension frame. And continuously transporting into the hole. The hoisting system is high in transportation efficiency and capable of saving working hours.
