Anchor cable tensioning equipment is an essential tool for pre stressing installation of anchor cables in coal mine tunnels. Ensuring that the anchor cable tension meets the pre stressing index is an important indicator for successful anchor cable installation. Pneumatic anchor cable tensioning equipment is particularly suitable for situations with explosion-proof requirements underground in coal mines. Pneumatic anchor cable tensioning equipment has a reasonable structure, reliable performance, simple operation, and safe use, making it particularly suitable for use in situations where explosion-proof requirements are present in coal mines.
