Product Features & Applications

Explosion-proof hydraulic prop complies with underground mine safety standards, all metal parts are strictly processed for anti-spark performance. Equipped with large-area cast iron base to prevent sinking on soft floor. Support force stable up to 300kN, maximum support height 3.15m, widely used in fully mechanized mining working face auxiliary support, safe and reliable for underground flammable and explosive environment

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.
