Unlike conventional jack legs designed primarily for maximum drilling speed, FACE WARRIOR 280LD Jack Leg Rock Drill under Japan standard for underground face drilling, tunnel construction, and rock bolting, features a sound balance between the leg and the drill. It is designed for underground drilling only. This ensures stabilized operation through a wide range of drilling angles. Moreover, the leg absorbs the drill vibrations so effectively that the operator can use it for many hours of fast drilling operation without excessive fatigue. Another feature is the concentration of all controls on the back head of the jack leg. This enables the operator to control the leg drill quickly and easily. The leg is as lightweight as it can be. Perfect leg-drill balance The drill recoil is absorbed by the leg owing to the integral design of the leg and drill, and consideration has been given to produce full power continuously. Performance equal to air flushing The automatic water-feed device and the constant impact and lubricating mechanisms serve to give the same performance as a comparable drill with air flushing. Adaptable to long-hole drilling Long-hole drilling is possible with FACE WARRIOR 280LD's powerful impact mechanism and strong rotating force, and it is equally efficient in drilling also of small-diameter holes. Automatic water-feed device Water is instantly fed automatically as soon as the drill is started by working the throttle valve handle, and is automatically stopped when the drill operation ceases. Powerful blows can be affected by utilizing the same handle. DRILL PANGOLIN 280LD support leg/pusher leg is also fitted in TOYO 280LD jack legs. |
