Cross type articulated roof beam can realize cross connection between horizontal and vertical beams, greatly enhance the overall stability of support frame. High tensile steel material, impact resistant and pressure resistant, ideal for irregular roadway top plate supporting in coal mines.
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:
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.
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.
Perfect Matching Performance: Special reserved contact surface, stable fit with DW series single hydraulic props, avoid sliding between prop top cap and beam.
Underground Anti-corrosion Design: Whole beam surface with thick anti-rust paint spraying, resist humid, dusty underground mine environment, extend service life.
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.
