HL532B Horizontal Directional Drill

The HL532B Horizontal Directional Driller is development 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.

Features

Drill pipe changing system: The semi-automatic pipe changing system patent drill pipe changing system, accurate localization, safety credibility, effectively reduces the labor intensity, increase the working efficiency.

Anchor system: Four anchor rods automatic anchor system, its very credible and easy operating.

Diesel engine: Steyr WD615 engine, it is powerful with convenient service.

Clamp:Top opening design clamp could be observed directly and make drill pipe changing easier.

Wired traveling controller : Adopting the electron-hydraulic traveling controller. The operation can be away from the machine. Its more safety and comfort.
