Our workover rigs are precisely engineered to match the diverse operational needs of oilfield projects, with lifting load ranges from 20t to 225t, and classifications by walking chassis (vehicle-mounted, self-propelled), power type (single-engine, twin-engine, electric, dual-power), derrick type (single-section, double-section), function (workover rig, drilling and workover rig, desert workover rig, tidal flat workover rig, inclined well workover rig, blowout prevention workover rig), structure type (double-drum workover rig, no guyline workover rig, snubbing workover rig), and operating structure (crawler type, tire type). We directly address the unique, on-site pain points of three core user segments—oilfield operation teams, on-site maintenance technicians, and procurement professionals—each relying on our workover rigs to complete well workover, drilling auxiliary, and emergency treatment tasks efficiently and safely. Oilfield operation teams face critical challenges: mismatched rig types for complex terrains (e.g., muddy low-lying areas, deserts, tidal flats) lead to delayed construction; insufficient lifting load capacity causes operational inefficiency or safety risks; unreliable power systems result in unplanned downtime; and difficult relocation wastes valuable time. Maintenance technicians need workover rigs with simple, sturdy structural designs, easy-to-access components, and clear maintenance guidance—avoiding complex disassembly processes that increase labor costs and extend downtime. Procurement professionals struggle with sourcing workover rigs that meet strict industry standards (API 7K, ISO 9001), match specific project needs (load capacity, terrain adaptability, power type), balance quality and cost, and come from reliable supply channels that ensure consistent performance. The core purpose of our products is to eliminate these pain points by providing high-quality, customizable workover rigs across all classifications and models—from 20t small-tonnage to 225t large-tonnage, from tire-type for rapid relocation to crawler-type for harsh off-road conditions—all designed to withstand the extreme environments of oilfield operations, improve construction efficiency, ensure operational safety, and reduce overall project costs.

Inspection found the wire rope had broken strands (exceeding the safe wear limit) and the winch’s brake pad was severely worn, causing the system to shut down automatically. Solution: We delivered our original wire rope and brake pad for the COOPER LTO-350 to the site quickly, and provided step-by-step maintenance guidance. The maintenance team replaced the damaged components, lubricated the winch, and tested the lifting system. The fault was resolved in 2 hours, and the rig resumed normal operation—avoiding further delays.
Case 3: Power System Downtime in Dual-Power Rig (120t)
A 120t dual-power workover rig (engine + electric motor) experienced sudden power failure during a long-term workover operation, with both power sources failing to start—posing a risk of tool stuck in the well. Inspection revealed the engine’s fuel filter was clogged, and the electric motor’s power cable had a short circuit due to wear. Solution: We provided original fuel filters and power cables, and guided the maintenance team to replace the clogged filter, repair the short circuit, and test the power switching mechanism. The rig’s power system was restored in 1.8 hours, and the dual-power backup ensured no tool loss or further operational delays.
