1. The winch and power head are regulated by dual frequency converters to ensure precise matching of their rotational speeds.
2. Unique lifting and pressurization device technology, with small pile forming errors and high bearing capacity.
The high torque power head reducer is matched with variable frequency speed regulation to meet the construction requirements under various working conditions, with high precision in pile forming and saving concrete.
The lifting and pressurization closed-loop chain structure is designed with precise speed matching, good pile forming, minimal error, no waste of concrete, and can effectively improve the bearing capacity of the pile.
The drill rod and drill core tube are made of high-strength seamless steel pipes, and the blades are made of cast alloy steel, ensuring that the pile shape is regular while having extremely high durability& nbsp;
