The Land Mechanical Drilling Rig LT ZJ20 is a lightweight 2000m-class full mechanical drive land drilling rig, manufactured strictly in accordance with API 4F, API 7K and ISO9001 international industry standards.
The Land Mechanical Drilling Rig LT ZJ20 is a lightweight 2000m-class full mechanical drive land drilling rig, manufactured strictly in accordance with API 4F, API 7K and ISO9001 international industry standards. Optimized for shallow and medium-shallow well drilling, completion and routine workover operations, this LT lightweight version features simplified and reliable mechanical structure, low overall weight and flexible site adaptability. It is specially designed for scattered well groups, rural water wells, small-scale geothermal projects and shallow unconventional energy development. With no complex electrical control system, low site requirements and convenient transportation and installation, the ZJ20-LT rig delivers excellent cost performance and stable field performance, serving as the ideal lightweight drilling solution for small and medium-sized energy projects and civil engineering drilling worldwide.
Adopts classic pure mechanical transmission scheme with diesel engine centralized power output. The system features simple structure, strong anti-interference ability and stable torque output, completely adapting to remote areas without stable power supply. It has fewer failure points and extremely high operational reliability for long-term continuous shallow well cyclic drilling.
On the premise of guaranteeing standard 2000m drilling capacity, the whole machine is optimized for lightweight structure. The derrick, base and power unit adopt streamlined configuration with reasonable weight reduction, effectively reducing transportation pressure and foundation bearing requirements. It is suitable for low-bearing-capacity well sites and convenient for frequent cross-region migration.
The rig adopts integrated modular skid layout with highly centralized functional units. It does not require complicated assembly and calibration procedures during field installation, greatly shortening rig-up and commissioning cycle. The intuitive mechanical operation logic reduces operator learning cost and on-site operation difficulty.
Equipped with universal standard wearing parts and mature mechanical matching structure. The whole machine avoids high failure rate of electronic and hydraulic complex systems, with low daily maintenance difficulty and low spare parts reserve cost. It significantly reduces long-term comprehensive investment for small-batch and frequent migration projects.
Key structural steel parts adopt weather-resistant anti-corrosion treatment. Core moving components are optimized with dust-proof, wear-resistant and wide-temperature adaptive design. The rig can work stably in plains, hills, pastoral areas and other conventional terrains, adapting to high-temperature, dry and low-temperature mild cold environments.

In fields developed before the AC VFD era, shallow 2000 m holes were routinely finished by compact mechanical units, and the economics of those campaigns still point the same way. The LT-ZJ20 land mechanical drilling rig is the lightweight answer in our fleet: a 2000 m nominal depth on 114 mm pipe, a 1350 kN static hook rating and a 440 kW (590 HP) drawworks over a ZP205 rotary head. Its diesel-only driveline needs no on-site electrical house at all, which is why it suits isolated well clusters, rural water wells and small geothermal jobs where laying power distribution would cost more than the drilling programme. The weight-reduced derrick and integrated skid also lower the foundation load, so weak ground can take the machine.
When you send an LT-ZJ20 enquiry, lead with your maximum planned depth, the bearing capacity of the ground, and whether the site has any mains supply. The 26 mm wireline on 4 x 5/8 lines is standard, as is the -30 C to +50 C envelope and construction to API 4F, API 7K and ISO 9001. If your wells will regularly exceed 2000 m or pull heavy intermediate casing, the LT-ZJ30 is the step up rather than over-speccing this lightweight unit; say also if the job includes shallow workover, because the travelling equipment can be matched to it.
Because this class of mechanical land drilling rig is often bought by smaller crews on their first machine, it can be supplied with a full operator training package either at your site or at our Jingzhou factory, so the hands on the drawworks understand the clutch-and-brake logic before spud. Pricing is built around the diesel brand, any optional hydraulic assist and the pump package, with a written offer within two working days of your well data.
Optional low-temperature cold-resistant modification package for alpine regions; enhanced dust and sand-proof structure for dry and windy areas; anti-corrosion coating for humid and coastal operation sites.
Further optimize module weight and dimension layout to adapt to narrow well sites and limited transportation conditions, improving overall migration flexibility.
Support diesel engine brand selection and power tuning to adapt to different altitude, fuel quality and construction intensity requirements.
Optional hydraulic assist system and basic drilling parameter monitoring module to improve operation efficiency on the basis of lightweight mechanical main drive.
Custom equipment color painting, brand logo marking, dedicated spare parts package and full-cycle after-sales technical support are available.
