Características y aplicaciones del producto

The single hydraulic prop is independent roof support equipment specially used for underground coal mine working faces and roadways. It features simple structure, quick lifting and unloading, stable supporting force, with explosion-proof and anti-rust hydraulic design. Matched with metal hinged beam, it realizes safe temporary roof protection, widely applied in small coal seams, gateway tunneling and local supporting operations in coal mines, metallurgy underground tunnels.

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.
