HW Series Hydraulic Drilling Rig is a widely used lightweight drilling machine. It is extensively applied in well drilling for buildings such as railways, water conservancy, bridges, dam foundations, geological exploration, geological core drilling, small grouting holes, and blast holes. The drill bits, such as diamond, composite sheets, and alloys, can be selected based on different geological conditions.
Product Features:
Equipped with a hydraulic automatic feeding mechanism to enhance drilling efficiency and reduce labor intensity.
Utilizes a ball and card holding mechanism or hydraulic chuck, allowing non-stop rod change for convenient operation.
Comes with a bottom hole pressure gauge for easy monitoring of the hole conditions.
Compact structure, centralized handles, small footprint, light weight, strong disassembly capability, and easy relocation.
