Penetrating hard ground! In addition to leaderless foundation machines, construction is also possible with cranes.
The "Down-the-Hole Hammer Method" is a technique where a down-the-hole hammer is attached to the tip of a drill during drilling with an auger, utilizing the discharge of air to create a piston motion (impact force) that drills through hard ground. This method is suitable for excavating all types of ground, from general soil to boulders, cobbles, and hard rock, and it can reliably excavate hard rock formations that are not feasible with other methods. Due to its simple structure, it has very few consumables, is easy to disassemble and assemble, and features a low bit load at the tip, resulting in good vertical accuracy. 【Related Product Lineup】 ■ TDH-EN Series ■ TDG-M Series ■ Line Oiler ■ Vegetable Oil ■ High-Pressure Air Hose ■ Products for Hammer Disassembly *For more details, please feel free to contact us.
