The Truck Mounted Workover Rig LT XJ1100 is a high-load high-mobility truck-integrated workover rig, strictly designed and manufactured in accordance with API 4F, API 7K and ISO9001 international industry standards.
The Truck Mounted Workover Rig LT XJ1100 is a high-load high-mobility truck-integrated workover rig, strictly designed and manufactured in accordance with API 4F, API 7K and ISO9001 international industry standards. Upgraded on the basis of light-duty truck-mounted workover rigs, this model is tailored for 3000m-class medium-deep oil and gas well heavy-duty workover, downhole complex fault treatment, wellbore reconstruction and old well stimulation operations. It integrates high-load derrick, high-power drawworks, matched power unit and integrated control system on a reinforced heavy-duty off-road truck chassis. While retaining full self-propelled rapid transfer capability and flexible field deployment advantages, the rig achieves a comprehensive upgrade in lifting load and deep-well operation capacity. Featuring strong terrain adaptability, high operation efficiency and reliable heavy-load performance, it is widely applicable for medium-deep oilfield daily maintenance, complex well condition overhaul and mobile workover engineering, serving as a high-performance mobile workover solution for medium and large-scale onshore oilfield service projects worldwide.
Adopts upgraded reinforced heavy-duty off-road truck chassis with overall load-bearing optimization. High-load derrick and heavy-duty drawworks are highly integrated with the carrier, realizing self-driving transition without towing equipment. It retains excellent cross-country trafficability for oilfield dirt roads, mountain roads and muddy roads, solving the problem of poor mobility of traditional heavy-duty skid-mounted workover rigs.
On the premise of ensuring 3000m medium-deep well heavy-load operation performance, the overall structure is scientifically optimized for weight reduction and compact arrangement. The streamlined high-strength derrick and integrated power skid effectively control the whole machine volume and dead weight, avoiding the bulky defect of conventional heavy-duty workover rigs, and greatly improving the flexibility of cross-well and cross-region rapid migration.
Equipped with industrial-grade full hydraulic automatic mast erecting and retracting system, supporting one-key rapid lifting and folding. No large hoisting equipment is required for on-site deployment, which significantly shortens rig-up and rig-down cycle and improves construction efficiency. The derrick is made of high-strength low-alloy steel, with enhanced structural rigidity, wind resistance and anti-fatigue performance, adapting to long-term high-intensity heavy-load cyclic workover operations.
Matched with upgraded high-power mechanical-hydraulic compound transmission system, featuring strong low-speed high-torque output and excellent variable-load adaptability. It can stably cope with complex working conditions such as deep well pipe string sticking, high wellbore resistance and variable formation load, with stable power output and ultra-low failure rate, fully meeting heavy-duty workover demands of medium-deep wells.
Configured with multi-group large-tonnage synchronous leveling hydraulic outriggers, which can realize rapid horizontal calibration and stable support on conventional well pads without professional foundation hardening treatment. The integrated centralized control system is simple and efficient, with low operation threshold, and universal standard accessories greatly reduce daily maintenance costs.
All key load-bearing steel structures adopt multi-layer weather-resistant and anti-corrosion treatment. Hydraulic sealing components, electrical systems and moving parts are equipped with dust-proof, sand-proof, moisture-proof and wide-temperature resistant protection modules. The whole machine can operate stably in alpine low-temperature, desert high-temperature, windy and dusty, and arid field environments.

The well that needs a workover never files a budget request first: a failed downhole pump, a water breakthrough or a stuck string turns a quiet production month into an urgent call-out, and the rig that rolls up first usually sets the recovery date. The LT XJ1100 truck mounted workover rig is built for exactly that middle band — 3000 m-class medium-deep wells on 73 mm pipe, with an 1100 kN static hook load and a 330 kW (450 HP) drawworks — and the LT lightweight layout keeps the unit compact enough for mountain and muddy oilfield roads. The mechanical-hydraulic compound drive and the ZP205 rotary table cover routine pulling, tubing work and the occasional fishing job, while the 26 mm wireline on the 5-by-6 line system gives a dependable hook for medium-deep completions. It drives itself between pads at up to 75 km/h, with no tractor and no crane needed to raise the mast.
For an LT XJ1100 quotation, the inputs that actually change the build are your worst-case string weight, the standpipe pressure the work demands, and whether coal-bed methane or tight-gas completions sit in the well mix. The 28 MPa standpipe working pressure sets the ceiling for circulation and squeeze jobs — tell us if your programme needs cement squeezes or fracturing flowback and we will confirm the iron rating. Because the derrick and synchronized outriggers level themselves on a normal pad, also note the pad condition and the coldest expected site temperature, since the -30°C lower bound decides whether the cold-start option is required.
The rig is released for delivery within a mutually agreed schedule after factory acceptance tests, and a complete operating and maintenance document set accompanies the machine in the language your crews work in.
Optional ultra-low temperature cold-start and structural anti-brittle upgrade for alpine high-latitude regions; enhanced full-system dust and sand prevention for desert arid oilfields; heavy-duty anti-corrosion coating for coastal high-humidity operation sites.
Optimize chassis bearing capacity, suspension system and off-road tire specifications according to customer road conditions, adapting to mountainous, muddy and complex road transportation and operation requirements.
Support hydraulic system pressure matching upgrade and power output curve tuning to enhance deep-well heavy-load lifting efficiency and complex formation adaptability.
