Unilateral Roof Cutting Bracket for Zqs28/2000-26/52 in Coal Mining¹

Product DescriptionUnilateral Roof Cutting Bracket(single Column Advanced Bracket)1. The hydraulic telescopic bracket for borehole coal mine has a simple structure and can quickly set up the support structure.2. The hydraulic telescopic bracket for borehole coal mine has a large supporting force, which can meet the roof pressure requirements and prevent the roof from sinking and deforming.3. The hydraulic telescopic bracket for borehole coal mine moves with the grab car for cyclic support.Brand: Liaoning XinfengProduct origin: Diaobingshan , Tieling LiaoningDelivery time: According to order quantitySupply capacity: 100,000 pieces/yearProduct DescriptionIntroduction of underground hydraulic support:The hydraulic telescopic bracket for borehole coal mine is a special support equipment for the advance support section of the two lanes of the comprehensive mining working face, which is usually arranged in the return air lane. The underground hydraulic support has a simple structure and strong supporting force, which can fully meet the roof pressure requirements. The bracket is transported from the end to the front by the lifting car to form a large circulation transportation, which not only ensures the integrity of the roof of the advance support section, but also solves the problem of roof management.Advantages of underground hydraulic support:1. The special support for the mining industry adopts a single-column bearing structure, which can realize fixed-point top cutting and support to maintain the support effect.2. Special support for the mining industry has a simplified overall design, fewer components, and light weight, which is convenient for on-site transportation, installation and adjustment, and improves construction mobility.3. Special support for the mining industry can customize the pillar height, stroke and load-bearing parameters according to the tunnel section, geological conditions and support requirements, and has a wider range of applications.SpecificationItemTechnical ParameterUnitModelZQS28/2000Support height1800-3600mmSupport width700mmCenter distance800mmInitial support force(P=31.5MPa)1545kNWorking resistance (P=38.5MPa)2000kN                Minimum transport dimensions                   (length × width × height)2400×700×1600mm                         Working dimensions                             (length × width × height)2800×700×3600mmOperation methodManual/remote controlTotal weight2000kgApplication of underground hydraulic support:1. The top cutting area of the two lanes of the comprehensive mining working face: Special support for the mining industry is suitable for temporary support on the coal wall side or the top cutting side, effectively relieving the roof pressure and preventing roof collapse.2. Advanced support section of the transport lane and return air lane: Underground hydraulic support is used for auxiliary support of the advanced section of the two lanes, and is used in conjunction with the sliding advanced support to improve the overall support effect.3. The intersection area of the upper and lower exits (T-shaped mouth): Underground hydraulic support can solve the support problems in areas with irregular space or difficult support.4. Areas with broken roof and concentrated pressure: Especially suitable for areas with frequent pressure fluctuations, enhancing local support capabilities and improving operation safety.Company ProfileAbout us: We are a high-tech modern enterprise integrating independent research and development, equipment manufacturing, engineering services, equipment leasing and sales services.
