Introduction
A Single Hydraulic Prop uses hydraulic pressure to provide temporary roof support in underground mining operations.
Features
1.Easy operation
The hydraulic control valve enables rapid lifting and lowering of the support columns.
3.Hydraulic Pressure-Controlled Support
Hydraulic pressure drives the piston rod to extend and retract, allowing controlled roof support and release.
2.Adjustable Height
The pillar height can be adjusted between 1.2 m and 4.5 m depending on coal seam thickness and underground roof conditions.
Applications
1.Roof Support in Longwall Working Faces
Used to support the roof in coal mining longwall faces during extraction operations.
2.Roadway Excavation Support
Applied to support roofs in roadway driving and tunneling as part of underground mine development.
3.Temporary Maintenance and Repair Support
Used for temporary support tasks during underground maintenance, emergency repairs, and stoppage work.
4.Support in Variable Seam Thickness Conditions
Suitable for roof support in thin, medium and thick coal seam mining faces.
Company Service
1.Regional Service Presence
Service engineers are deployed by sales region, with local support points in key markets.
2.Application-Based Technical Support
Model selection and support scheme design based on actual mine conditions.
3.On-Site Training Before Use
Operators receive practical training and ground demonstration before underground operation.
