产品特点与应用

The articulated roof beam is matched supporting accessory for single hydraulic props in underground coal mines. It adopts integral high-strength alloy steel welding structure with hinged connection design, realizing continuous roof protection and uniform pressure bearing. It is lightweight, easy to assemble and disassemble, widely used for temporary roof support in tunneling roadways, thin coal seam working faces and underground maintenance operations.

This mining articulated roof beam is manufactured by one-piece thick steel plate welding, consisting of beam body, hinge joint, connecting pin and top anti-slip structure:
  1. High Bearing Structure: Integral reinforced steel beam body, uniform force dispersion, rated bearing capacity up to 300kN, effectively share roof rock pressure and prevent local collapse.
  2. Quick Hinged Connection: Standard hinge socket + matching connecting pin design, multiple beams can be connected end to end to form continuous supporting row, flexible layout according to roadway width.
  3. Perfect Matching Performance: Special reserved contact surface, stable fit with DW series single hydraulic props, avoid sliding between prop top cap and beam.
  4. Underground Anti-corrosion Design: Whole beam surface with thick anti-rust paint spraying, resist humid, dusty underground mine environment, extend service life.
  5. Portable Assembly & Disassembly: Moderate single weight, easy manual carrying underground; quick pin disassembly without auxiliary tools, greatly improve supporting operation efficiency.
  6. Wide Application Scenarios: Mainly used for tunneling advance support, small coal face temporary support and underground maintenance supporting, compatible with all types of single hydraulic props.
