2. The front outriggers are narrow and the rear outriggers are wide, with diagonal supports forming an inverted triangle; during slewing, the front outriggers affect a small area, making it easy to drill piles at foundation pit corners.

3. The whole machine is heavy, with strong overload capacity and a high safety factor, and it is stable and reliable during operation.

4. With the whole machine positioned once, 4—6 piles in two rows can be driven at the same time, increasing efficiency by 30 percent.

5. The drill pipe has a reasonable structure, good material quality, thick blades, strong interchangeability, and high concentricity.

6. It adopts a multifunctional pile frame that can be equipped with other power units for construction, achieving multiple uses in one machine.

7. The traveling wheels run on the steel rails of the crawler shoes, making them sturdy and durable.

8. The pile driver chassis is towed as a whole, eliminating the need for on-site disassembly and reassembly.

9. Various types of drill bits are available to handle construction in various complex strata.

10. The sliding plates are equipped with nylon sleeves and nylon plates for wear resistance and to protect the slideways.

11. The advanced hydraulic walking-type traveling method provides a longer walking step distance, meeting the requirements of construction on harsh sites.

1 2. In addition, for CFG pile drivers of 20 meters (including 20 meters) or less, the entire boom and outriggers fold onto the frame, and the whole machine is towed during transportation. On-site entry is controlled hydraulically, making raising and lowering the boom convenient, quick, time-saving, and labor-saving. The main machine pulley has already been threaded with the wire rope; during assembly, it can start drilling simply by inserting a pin shaft with the power head.
