a small size yet large channel, ensuring unobstructed air intake.

●Fragments collection and discharge device:

With multiple paths for fragments of stone entry and a single pipe for discharge,environmentally friendly in construction.

●Inner discharging drill pipe:

Double-layer and multi-channel drill pipe enables inner slag-discharging. its unifomm diameterfrom top to bottom helps prevent hole collapse.

●Connector:

The high-strength V-shaped fragments-collecting structure comes with a guiding function, allowsfor the switch from forward to reverse circulation discharging.

●Cluster hammer:

Special unified specification sub-hammers are desianed for hammer-lifting and air-sealing. Theyare cost-effective, achieving high fragment-discharging efficiency in both inner and outer pipes.avoid repeated crushing at the hammer bottom, and increasing construction efficiency.

●Hydraulicopening-and-closing gripper:

It ensures accurate hole positioning and is easy to operate

●Comprehensive technical support:

Provide complete construction methods based on user needs and existing eauipment conditions;Customization and restructurina of complete sets of eauioment;Collaborative construction.
