Características y aplicaciones del producto

Heavy load hydraulic prop with thickened cylinder wall and reinforced top cover structure, ultimate bearing capacity up to 350kN, maximum support height 3.5 meters.It is suitable for large cross-section roadway and deep mining underground projects. Adopts external liquid injection operation mode, convenient for centralized pump station supply, greatly improving working efficiency of underground support operation.

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.
