Introduction
Suspended hydraulic struts are underground mine support components used to provide temporary roof support in coal mining operations.
Features
1.Integrated Load-Bearing Structure
The main column is a monolithic steel tube (Q345B) without segmental splicing.
2.Controllable Scaling
The extension process is controlled by a hydraulic valve and an internal reset spring. Stroke ranges such as 800–1400 mm and 1000–1800 mm.
Application
1.Coal Mine Roof Support
Provides primary roof support along longwall and working faces.
2.Face End and Side Support
Reinforces the ends and sides of coal mining panels under load.
3.Thin to Thick Seam Adaptation
Used in thin, medium and thick coal seams due to wide load and stroke range.
4.Mechanized Mining Integration
Works with roof beams and mechanized systems for continuous support.
