ZJ 40(850hp) CZ Truck-Mounted Drilling Rigs(Workover depth: 7,500 meters)

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.

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.
