Our hydraulic air actuated down hole hammer is a new type of pile foundation construction equipment mainly used to drill into bedrock. It integrates the functions of rotary drilling rig, down-hole hammer, and hydraulic diaphragm wall grab, and has many superior processing properties. The down-hole hammer is driven to impact the rock, aiming at smashing the rock and cut the rock into pieces. This machine discharges materials by air-lift in reverse circulation way and air direct circulation way. Besides, it realizes the fast continuous drilling of big cross-section original rock. What’s more, the host machine can conveniently switch between the functions of impacting, rotary digging and long screw drilling.

Features of Hydraulic Air Actuated Down Hole Hammer SH25H
1. For different geologies, this down hole hammer can use multiple drills.
2. Its big triangle structure provides high stability.
3. The hydraulic pneumatically actuated down hole hammer can drill the bedrock.
4. A screw air compressor is matched with the machine, which greatly enhances the drilling efficiency.
5. It is equipped with an elastic drilling rod, which effectively avoids the complex work of adding drilling rod.
6. With a rotary head swinging at 180 degrees, our hydraulic air actuated down hole hammer can easily switch drilling and impacting functions.
7. The rubber hose winch system enables the air inlet hose and the air exhaust hose to spread or intertwine timely as the depth of the drilling hole changes.
