In rotary drilling rig operations, rotation speed and torque settings are not fixed but must be dynamically adjusted based on geological conditions. Use high speed, low torque for soft soil; medium-low speed, medium-high torque for sandy gravel layers; and low speed, high torque for rock layers. The core principle is: Torque determines if it can drill, while rotation speed determines how fast it drills. The two must be perfectly coordinated for efficient and safe construction. Read More

As a core pile-driving equipment in the infrastructure engineering field, the technical level of rotary drilling rigs directly affects the efficiency, accuracy, and environmental friendliness of pile foundation construction. In recent years, with the upgrading of global infrastructure demand and the Read More

In the field of construction engineering, rotary drilling rigs are the 'main force' in pile foundation construction. Used rotary drilling rigs, simply put, are those that have been used once or multiple times and have flowed from the original owner to the market. They are not 'old and scrapped equip Read More

Among the entire set of equipment for a rotary drilling rig, the power head is undoubtedly the "heart" - it is not only the core component for transmitting power, but also directly determines whether the drilling rig can complete the drilling operation efficiently and stably. If the drill pipe is th Read More
