产品特点与应用
DW2.6 single hydraulic prop is specially designed for underground coal mine tunnel roof supporting. It uses thickened high-pressure seamless steel pipe as cylinder body, with integrated three-purpose valve to realize quick jacking up and pressure relief lowering. The rated working resistance reaches 250kN, good pressure resistance and anti-bending performance, suitable for medium-height mining face roadway support, easy to install and recycle repeatedly.
This underground single hydraulic prop adopts double-stage telescopic cylinder structure, composed of outer cylinder, inner cylinder, movable plunger, three-use valve, base and top cap:
1. Hydraulic Lifting System: Adopt integrated three-use valve for fast liquid injection lifting and manual unloading retraction, simple operation without complex control system.
2. High-strength Load Structure: Thickened seamless steel cylinder, large contact base and top cap to disperse pressure, stable supporting capacity up to 250kN, effectively control surrounding rock roof.
3. Mine Safety Design: All internal hydraulic parts meet coal mine explosion-proof standard Ex I Mb; outer wall anti-rust spraying, adapt humid underground gas environment.
4. Matching Combination: Perfectly matched with metal hinged roof beam to form temporary support unit, flexible layout for narrow roadway and thin coal seam working faces.
5. Portable & Low Maintenance: Light single-piece design, easy transportation underground; fewer vulnerable parts, quick on-site replacement to reduce downtime.
6. Wide Adaptability: Multiple height specifications optional, fit roadway slope within ±12°, applicable for tunneling, small fully-mechanized face and repair supporting.
