The trailer-mounted drilling rig is a highly mobile and modular drilling system designed for efficient transportation, fast rig-up, and reliable performance in a wide range of onshore drilling environments. It is suitable for both modular split-transport configurations and integral-frame designs, significantly improving relocation efficiency and operational flexibility.
Trailer-mounted Drilling Rig with Separate Main Frame
This series (GW-M1000, ZJ10DBT, ZJ30DBT, AJ40DBT) adopts a front–rear split modular structure, optimizing transportation and field assembly efficiency.
Structural Features
- Front module includes drill floor and rotary table drive system
- Rear module integrates drawworks drive and power system
- Designed for efficient road transportation and rapid site installation
- Front substructure available in telescopic or semi-trailer mounted design
- Rear module adopts semi-trailer mounted configuration
Technical Features
- Two- or three-section telescopic mast design for flexible operation
- Mast can be transported together with main module or separately
- AC VFD motor drive system for stable and efficient power transmission
- Optional diesel-electric compound drive system available
- Modular design ensures excellent mobility and quick installation
- Independent driller’s cabin integrates air, electrical, hydraulic controls and drilling parameters for centralized operation
- Supports full drilling control within cabin, improving working comfort and reducing labor intensity
- Optional automatic drilling system and top drive system available
Trailer-mounted Drilling Rig with Integral Main Frame
This series (ZJ40/2250DT, ZJ50/3150DT, ZJ70DT) is designed for medium to deep drilling operations (4,000–7,000 m), particularly suitable for desert, Gobi, and relatively flat terrain conditions.
Structural Features
- Advanced AC-SCR-DC or AC-VFD-DC electric drive technology for high drilling efficiency
- Modular or parallelogram substructure system, lifted by drawworks or hydraulic cylinders
- Telescopic mast or K-type mast structure with optional top drive integration
- Main frame, mast, and power unit can be transported either integrally or separately
Technical Features
- Highly modular design reduces transportation requirements to approximately one-third of conventional rigs
- Moving time reduced to about one-quarter compared with standard drilling rigs
- Lower transportation cost and higher relocation efficiency
- Mast and power systems can be transported via wheel-based mobility systems
- Compatible with top drive drilling systems for enhanced performance
- Designed for fast deployment and efficient operation in remote oilfield environments
This trailer-mounted drilling rig series combines modular engineering with advanced drive technologies, delivering outstanding mobility, reduced transportation cost, and high operational efficiency. It is an ideal solution for modern oilfield drilling operations requiring rapid relocation and flexible configuration.
