Products Description
This product is the truck-mounted drilling rig which has the highest drilling depth among the truck-mounted drilling machines we have produced. It is also the largest self-propelled light-duty drilling equipment in the world. Our product can be used in exploration engineering to drill oil wells with the depth lower than 4000m.
Features
- Our truck-mounted drilling rig features a highly reliable dual-engine parallel operation power system, integrated with a compound transmission system based on gear transfer cases. The two diesel engines can operate independently or in parallel depending on operational demands, significantly enhancing system redundancy and ease of maintenance.
- The rig is mounted on a reinforced 14×10 chassis, engineered for optimal load distribution and exceptional cross-country mobility, ensuring stable performance even in rough terrains.
- The 39-meter derrick, along with the main frame and key components, is constructed from specially selected materials with an optimized structural design, achieving a combination of high durability and reduced weight. This contributes to greater convenience during rig relocation.
- For enhanced operational safety, the drawworks braking system consists of a hydraulic disk brake serving as the main brake, complemented by an Eaton pneumatically controlled water-cooling auxiliary brake for reliable backup performance.
- The foldable drill floor features a robust structure, allowing for quick setup and stable support during drilling operations.
