The Trailer Mounted Drilling Rig ZJ40DBT is a heavy duty trailer integrated mobile drilling rig intended for 3000 4000 m medium deep well drilling assignments.
The Trailer Mounted Drilling Rig ZJ40DBT is a heavy duty trailer integrated mobile drilling rig intended for 3000 4000 m medium deep well drilling assignments. Designed and manufactured per API 4F, API 7K and ISO9001 international standards, the whole drilling unit is assembled on a reinforced heavy duty highway compliant trailer chassis. Major core assemblies remain connected without full disassembly during site transfer; the rig can be towed integrally by a tractor truck. This rig is widely used for medium deep oil gas, tight gas, coal bed methane and geothermal well exploitation, and it is highly suitable for cluster well operations in remote areas lacking large tonnage lifting equipment.
Derrick, substructure, drawworks and main power assemblies are pre mounted on high strength trailer frame. After hydraulic folding, the whole rig meets road towing specifications, greatly reducing repeated disassembly assembly work when shifting between well pads.
Large bore built in hydraulic cylinders realize on site derrick raising and lowering. External truck crane is not required for rig deployment, cutting auxiliary equipment cost and shortening well site preparation cycle.
Variable frequency drawworks and rotary table deliver stable and adjustable high torque output. It achieves precise weight on bit control for medium deep complex strata, improving drilling efficiency and borehole stability.
Folded outer dimensions are tailored for narrow mountain roads and compact well pads. Modular partition design ensures high structural rigidity without sacrificing cross region transport capability.
Vulnerable wearing components adopt universal oil field standard parts. Trailer suspension, brake and lighting system fully comply with highway transportation regulatory requirements.

The ZJ40DBT trailer mounted drilling rig is the answer for 3000-4000 m programmes where the wells move but the budget cannot stretch to a full modular split fleet. Rated 4000 m on 114 mm drill pipe with a 2250 kN static hook load and an 800 kW drawworks, it keeps derrick, drawworks and power units connected on the reinforced highway trailer — a single tractor tows the whole unit between pads without disassembly, which matters enormously in remote areas where no large-tonnage crane exists for a conventional rig-up. The AC VFD main drive with hydraulic auxiliary system balances control precision and field simplicity for medium-deep oil, gas, coal bed methane and geothermal wells.
An inquiry for a ZJ40DBT drilling rig supplier quotation should state the pad-to-pad distance and the road conditions between them, plus the lifting resources available at site. Because the rig migrates as a unit, transport permits and axle-load limits become part of the selection — our export engineers dimension the tow configuration and provide the documentation package for cross-border movement. If your wells are clustered rather than spread over long distances, this is where the trailer class wins over both skid and truck-mounted alternatives.
We quote the ZJ40DBT per configuration after reviewing your well depth spread and migration plan; a benchmark price typically returns within 48 hours.
Optional hydraulic oil heating unit, low temperature resistant sealing assembly and cold start auxiliary device for frigid working environments.
Customize trailer axles, brake assemblies and signal lighting to satisfy highway certification standards of different countries.
Full diesel driven configuration available for remote well sites without stable grid power supply.
Custom mounting bases and connecting pipelines for matching mud pump, mud tank and solid control skid system.
Support user specified painting color, brand logo marking and project dedicated complete spare parts kit.
