Introduction
The Suspended Hydraulic Prop is a modular mine support component designed for underground roof support.
2.Pressure‑Rated Steel Body
Key sections use 15–20 MPa structural steel, resisting deformation under full hydraulic load.
Application
Working Face Support: Stabilizes the roof along mining faces.
End and Side Support: Reinforces roadways, junctions, and face ends.
Temporary Support: Provides short-term support during repairs or temporary excavation.
High-Stress Seam Support: Handles variable roof pressures in thin to thick seams.
Company Service
We provide region-based after-sales support, with technicians assigned according to the sales area.
Technical assistance is available for product selection, basic operation guidance, and initial commissioning.
FAQ
Q: Do you supply directly from factory or through trading?
We are a manufacturer with our own production facilities.
Q: Are your suspension hydraulic props certified?
Yes. Our products undergo testing and meet relevant national mining equipment safety standards.
Q: How about your technical capability?
We have long-term experience in coal mine support equipment manufacturing. We were the first domestic manufacturer certified for a 5-meter single hydraulic prop, have cooperated with Shandong University of Technology on mining equipment development, and participated in the development of a 6-meter single hydraulic prop for Dongtai Group in 2025.
Q: Can this product be customized for specific project requirements?
Yes. We can modify technical parameters and design based on site conditions and customer needs.
