Hydraulic Supports
Overview
The hydraulic support is the roof-support equipment of a fully mechanized longwall face, supporting the roof and maintaining a safe working space while coordinating with the shearer and scraper conveyor for advancing and pushing. Our supports cover chock-shield, support-shield and top-coal caving types, with working resistance from 2000 to 20,000 kN.
Features
- Electro-hydraulic control for adjacent, skip and group automatic control
- High-strength welded steel structure with yield strength up to 960 MPa
- Double-telescopic legs with long stroke to suit varying seam thickness
- Pressure sensors for real-time support monitoring uploaded to the surface
Applications
Medium-thick seam longwall support, steeply inclined seam support, top-coal caving support and backfill mining face support.
Key Advantages
High support strength and good stability; high automation of electro-hydraulic control reduces underground personnel risk; long service life of structural parts.
