1. The folding mast structure of the HF530 hydraulic rotary drilling rig has the advantages of a simple structure with great durability and ease of maintenance throughout its working lifetime.
2. Using a high position-oriented structure for the frame, the drilling unit can realize a vertical position between the Kelly bar and ground. This increases work efficiency by a significant metric.
3. The power head features a unique patented structure, saving costs through efficiency and repair convenience.
4. Main windlass: The imported hydraulic pressure motor is designed for sensitive reaction and allows for free lowering with speeds up to 80m/min. The main winch is located in sight of the operating station in order to allow the operator to observe the winch during use.
