The HZ series cluster-type down-the-hole hammer is primarily designed for drilling large-diameter pile foundation holes in hard rock conditions. It utilizes a bundled down-the-hole hammer operation method, combining several sub down-the-hole hammers to work together, achieving the requirement of forming large-diameter pile foundation holes in one go. This innovation addresses the challenges of low efficiency and high costs associated with traditional methods when drilling large-diameter holes in hard rock environments.
The HJGW400S water well drilling rig is a multi-purpose, crawler-type hydraulic water well drilling machine independently developed and produced by our company. Its key components are imported from abroad, ensuring the stability of the drilling rig. The maximum drilling depth can reach 400 meters, with a drilling diameter ranging from 110 to 305 mm, meeting the engineering needs for geothermal and groundwater extraction, hydrogeological exploration, and pile foundation construction under various working conditions. This drilling rig boasts advantages such as high lifting capacity, high output torque, high work efficiency, flexibility, and good stability.
