Introduction of China Coal U-channel Clamp
U-channel clamp as a U-shaped steel bracket positioning, demanding a large force, security and stability, rugged durability, the use of the equipment manufacturing card cable to meet the requirements, and has a material saving, forming stable, high processing efficiency and low investment efficiency advantages.
U-channel clamp as a provides a reliable connection fasteners for U-channel steel support U steel lap length is generally not more than 200mm, the manufacturing process is simple, easy installation. U-shaped steel bracket safe and reliable, can improve the roadway life, reduce roadway maintenance rate, reduce security incidents, to ensure safety in coal mines.
U-channel clamp with a retractable cable and reliable carrying capacity to adapt to the load and deformation of soft rock, cross utilization is high, easy to stand back support small amount of maintenance, support recovery reuse rate, reduce prop use, environmental benefits are clear.
Main Parameter of China Coal U-channel Clamp
