1. The overall types of derricks are divided into A type, K type (front opening type), tower type, and mast type, etc
2.K-type derrick: That is, the front opening derrick. The front fan is open, with several spatial truss structures on the side. The two sides are divided into sections or blocks welded into several sections, and the back is a truss bar system. Each section and component is connected by pins or bolts, which can be installed at a low position and lifted as a whole by the power of a winch or a hydraulic cylinder. It has the advantages of convenient installation and disassembly and good overall rigidity.
1. High Structural Stability: The truss-type design ensures excellent rigidity, capable of withstanding heavy loads and wind forces, suitable for harsh environments.
2. Easy Assembly/Dismantling: Modular components allow segmented transportation and rapid on-site assembly, ideal for mobile drilling operations.
3. Superior Load Capacity: Designed for medium to deep drilling, with outstanding static and dynamic load performance.
4. Efficient Space Utilization: Open structure facilitates equipment layout and pipe handling, improving operational efficiency.
5. Strong Adaptability: Compatible with various drill rig types, widely used in land and shallow offshore drilling.
6. Cost-Effectiveness: Lower manufacturing costs and simplified maintenance offer high economic value.
