As mining operations go deeper, vertical lifting efficiency and safety have become major constraints on mine output. Designed for deep shafts, inclined shafts and complex terrain, our vertical lifting system works across 0 500 m vertical heights and supports steep angle, long distance material transport. Thanks to modular design, high throughput and full lifecycle services, it has gained wide attention in the mining material handling industry.   Three Core Solutions for Varied Lifting Applications Our portfolio includes three main product lines to cover diverse vertical transport demands. Steep Angle Sidewall Conveyor Solution Engineered as an alternative to conventional mine cages, this solution handles vertical heights from 0 m to 500 m. In inclined shaft conditions, throughput can exceed 10 000 tons per hour. It overcomes the low efficiency, intermittent nature of cage hoisting and enables fast, continuous material transfer from underground to surface. Pocket Type Vertical Lifting System Optimized for high height, high volume tasks, this system is ideal for muck removal shaft main lines and blind shaft intermediate transfer. Proven in tunneling projects, it runs stably above 250 m lift height with capacities over 800 m³/h. It fills performance gaps under tight space conditions and can reach lifting heights over 500 m. Long Distance Rope track Conveying System Boasting single spans beyond 2 000 m, this system serves mountain and river valley sites. It reduces transfer points, cuts energy consumption and lowers overall maintenance costs for difficult terrain material haulage. Full Chain “EPC+M+O” Service Model Beyond equipment supply, Bairui provides a complete EPC+M+O service package: E (Evaluation & Custom Design): Custom engineer conveyors and belts based on mine geology, production targets and existing site infrastructure. P (Core Equipment Manufacturing): In house production of sidewall belts, lifting pockets and drive units for reliable quality and on time delivery. C (Installation Guidance): On site technical support for installation and commissioning to ensure smooth startup. M (Operation Management): Partial or full operational outsourcing to help mines hit production targets quickly. O (Smart O&M): Condition monitoring and predictive maintenance platform for early fault warnings and optimized maintenance schedules. Key Benefits vs Traditional Lifting Equipment For shafts deeper than 500 m, traditional multi rope friction hoists suffer from short rope life, batch type loading and complex controls. The Steep Angle Sidewall Conveyor Solution fits compactly within limited shaft space. Its continuous output connects directly to processing plants or silos, eliminating intermediate stockpiles and re handling expenses. In tunnel construction, the Pocket Type Vertical Lifting System features small turning radii and steep climbing performance. It has replaced imported equipment on multiple inclined shaft tunnel projects, delivering local manufactured cost savings. It requires minimal maintenance space and tolerates heavy dust and poor water conditions.   Field Proven Project Experience Our solutions are operational across global metal mines, coal mines and large tunneling infrastructure. China’s first 255 m mine used vertical lifting system is now in service, boosting vertical conveying efficiency by over 10× with safe, energy saving and eco friendly operation. September Global Exhibition Roadshow This September, Bairuifu will attend four key mining expos across Central Asia, Africa and China to showcase our full vertical lifting portfolio and EPC+M+O service model. Industry professionals are welcome to visit our booths for technical exchanges.   Exhibition Schedule Mining World Central Asia 2026 Sep 16 18, 2026｜Atakent International Exhibition Centre, Almaty | Booth: 11 307   Electra Mining Africa 2026 Sep 7 11, 2026｜Johannesburg Expo Centre | Booth: P10   The 28th China Mining Conference and Exhibitlon Sep 10 12, 2026｜Meijiang Convention and Exhibition Center, Tianjin | Booth: N2 2607   The 20th Yulin International Coal and High-end Energy Chemical Industry Expo Sep 13 15, 2026｜Yulin Convention & Exhibition Center| Booth: H342 / H335  

Based on the experience of serving tunnel projects around the world, QBF rubber analyzes the common problems of tunnel sidewall conveyor belt as follows: Design Selection Error Design capacitycannot meet the actual demand, resulting in overload and material spillage in vertical section. Size of particles from TBM is not fully considered. The actual size is too large, causing impact damage to the belt. Belt is not able to well accommodatematerials with high water content. Material spills from belt two sides. Poor anti-stick performance leads to serious material carryback and hence limit the belt capacity. Improper Design of Key Parts Small pulley is selected; take-up and bend pulley are not properly arranged. Inappropriatetracking measures are used. Deflection wheels are not designed reasonably. Bad parts qualityand poor machining precision cause poor stability.     The design selection of the tunneling sidewall conveyor belt should be based on material characteristics, conveying requirements, environmental conditions and safety requirements and comprehensively consider the factors such as sidewall height, cleat design, rubber compound properties, belt width and speed. Only through scientific selection and reasonable design can the sidewall belt be ensured to operate efficiently, safely and stably in tunnel projects.     QBF Rubber provides the following solutions for sidewall conveyor belt design based on the characteristics of tunnel construction and different muck properties. ①The base belt adopts steel cord free zone design to protect cross rigidity. ②Anti-stick rubber compound is used to effectively reduce material carryback. ③The belt is configured with side blinkers to accommodate materials with high water content. ④Cleats are reinforced to resist to impact caused by large-sized material. TCS cleats are also available which enables quick replacement of damaged cleat blade. ⑤Hot vulcanized spicing delivers higher strength and longer service life.   QBF rubber has been focusing on European standard long-life sidewall conveyor belt to provide the fit-for-purpose solutions for tunnel projects. The market share of QBF rubber sidewall conveyor belt in tunnel project in China reaches 70% to support customer’s efficient construction.
