Mast drilling system * Introducing construction examples
Environmentally friendly large-diameter boring method effective for steel pipe pile construction and temporary work in narrow spaces.
The "Mast Drilling System" is a large-diameter boring method consisting of a rotary drilling machine (mast drilling machine) installed on an auxiliary mast and a crane (mast drilling crane) that suspends the drilling tools. By supporting the load of the crane with the auxiliary mast, the system reduces the crane's load, enabling either miniaturization of the crane or expansion of the working radius. A significant feature is the ability to freely attach and detach the crane and auxiliary mast. The construction method involves selecting the appropriate system from three drilling methods (air rotary method, down-the-hole hammer method, mud rotary method) based on site conditions. It addresses various challenges faced in conventional large-diameter boring projects, such as the desire to minimize the working space and reduce environmental impacts like noise, vibration, and dust. 【Features】 ■ The crane and auxiliary mast can be freely attached and detached ■ No noise or vibration is produced ■ No industrial waste is generated ■ Dust generation is minimized ■ The working space is small *For more details, please refer to the catalog or feel free to contact us.
