Small & Medium – HL532B

HL532B HDD, an innovative equipment and developed by huali heavy industry Co.,ltd. independently based on the advanced theory of trenchless technologies. Via total hydraulic control and hydraulic drive technologies, this device realize all actions of the drilling tool such as rotating, pushing, broaching, pullback and whole machine moving. It could be widely used in constructing and renewing pipeline in water supplying, coal gas, electronic, telecommunication, natural gas area to cross roads, railways, constructions, rivers and other areas not allowed to be excavated such as crowded street, culture relics, agriculture crops and mantle vegetation protected zones.

The HL532B Horizontal Directional Driller is a new drilling machine which developed independently based on well absorbing the domestic, overseas superior technology of the similar product and it unites the domestic market demand. The machine is characteristic of novel design, perfect performance, handsome shape, elaborate works, and boats high performance price ratio. The hydraulic system uses the variable system, with more adequate power and even more energy saving. The control system is widely used advanced controlling mode, such as pilot control and electron- hydraulic control mode, which the main hydraulic pressure components are imported. Flow rate of the mud pump is 320L, it can meet the construction requirement.

The semiautomatic patent drill pipe changing system, accurate localization, safety credibility, effectively reduces the labor intensity, increase the working efficiency. system, accurate localization, safety credibility, effectively reduces the labor intensity, increase the working efficiency.
