The shaft guided lifting system is a critical part of safe and efficient mine operations. It determines whether the conveyances (cage, skip, bucket) can run smoothly and accurately within the shaft. The two mainstream solutions are rigid guides and rope guides, each suited for different applications.
Fundamental Differences Between the Two Guide Types
Rigid guides are made of timber, steel rails, or structural steel, fixed to horizontal guide beams across the shaft cross-section. Based on material, they can be divided into timber guides, steel rail guides, sectional steel guides, and rolled steel guides. Their key features are high rigidity and accurate guidance, making them suitable for high-speed, high-capacity permanent mines.
Rope guides are the only flexible guiding solution, using wire ropes as the guiding device. The upper ends are fixed to the headframe or tower, and the lower ends are tensioned with counterweights or hydraulic devices. Temporary shaft hoisting systems use rope guide guidance, with the lower ends of the guide ropes fixed to the sinking platform and the upper ends pretensioned via sinking winches.

Wanfeng's Solutions
Hebi Wanfeng provides key supporting equipment for shaft guided lifting systems. The JZ series sinking winches are used for pretensioning and adjusting the guide ropes to ensure stable tension in the guide system. The bucket conveyances work with guide devices to ensure safe material hoisting during the sinking phase. The headframe and sheave are designed together to provide reliable upper fixing points for the rope guide system.
There is no one-size-fits-all answer for shaft guided lifting solutions. The choice depends on shaft depth, load requirements, and construction schedule. Rigid guides tend to favor long-term stability, while rope guides prioritize construction time and cost. Understanding their respective application conditions is the key to selecting the most suitable guiding solution for a given project.
