The 750HP Truck-Mounted Rig (XJ750 series) is a heavy-duty dual-power ultra-high horsepower workover and drilling unit, representing a flagship model in the truck-mounted rig product line. Equipped with a matched dual-engine power system and 14×8 multi-axle ultra-reinforced heavy-duty chassis, this rig breaks through the load and power limits of conventional 650HP and lower-grade models, supporting super-deep well workover and high-intensity heavy-load oilfield operations. Adopting an upgraded 38m high-strength trapezoidal lattice mast and full hydraulic heavy-duty drive system, the equipment integrates ultra-large hook load capacity, stable continuous operation performance and flexible self-propelled mobility. It is professionally designed for 8000-meter-level ultra-deep onshore oil and gas wells, large-scale oilfield heavy overhaul, and super-deep geothermal well projects. Fully compliant with API 4F and international petroleum machinery standards, the XJ750 truck-mounted rig delivers ultra-stable, high-efficiency and safe construction performance for super-large oilfields and extreme harsh working environments.
Adopts dual high-power diesel engine combined power output mode, forming a 750HP comprehensive power unit with explosive torque reserve. It provides lasting and stable power support for ultra-deep well heavy tripping, stuck pipe removal and high-resistance downhole operations, completely solving power attenuation problems of single-power high-horsepower rigs under long-cycle full-load working conditions.
Matched with upgraded heavy-duty traveling system and reinforced load-bearing components, the rated hook load reaches 1500kN, with a maximum static load of 1470kN. It perfectly adapts to super-deep well heavy-load construction requirements, far exceeding the load limit of conventional high-horsepower truck-mounted rigs.
Equipped with an upgraded 38m high trapezoidal lattice mast, featuring higher overall rigidity, stronger pressure and bending resistance than traditional masts. The automatic pull rod connection structure realizes rapid mast erecting and folding, effectively improving overall structural stability and construction safety during ultra-deep well operation.
Built on 14×8 multi-axle reinforced off-road chassis with large-span hydraulic telescopic outriggers, the support fulcrum distance is increased comprehensively. The whole vehicle features stronger anti-tipping performance and cross-country passing ability, supporting full-load integral transfer and long-term on-site heavy-load operation without deformation.
The fully enclosed luxury control cabin integrates high-precision real-time data acquisition, load dynamic feedback and multi-level safety interlock protection mechanisms. It realizes full-process visualized and precise operation of ultra-deep well construction, effectively avoiding operational risks in long-hour and high-intensity continuous working scenarios.
Optimized professional large-flow heat dissipation system, enhanced wear-resistant transmission components and dust-proof & anti-corrosion overall structure. It stably adapts to 24-hour uninterrupted heavy-load operation in high-temperature deserts, cold high-altitude areas and dusty oilfield environments, greatly reducing equipment failure downtime.

The following questions address common equipment selection and operating considerations.
The 750HP rig adopts an exclusive dual-engine combined power system with higher power output and torque reserve. It is equipped with a 150T super-large hook load and 38m ultra-high mast, supporting 8000m super-deep well operations. It is specially built for ultra-high-intensity heavy-load projects that 650HP single-power rigs cannot undertake, with stronger extreme working condition adaptability.
No. It retains the integrated self-propelled design. After mast folding and outrigger retraction, the whole equipment can travel independently at a maximum speed of 72km/h, eliminating high-cost large-scale hoisting and trailer transportation, realizing efficient cross-region relocation.
The standard XJ750 rig supports a nominal service depth of up to 8000m (with 2-7/8'' tubing). We can further customize relevant configurations to meet deeper ultra-deep well construction demands according to project requirements.
Yes. The whole machine is optimized for super-deep and heavy-load extreme working conditions. The dual-power system, reinforced structure and upgraded heat dissipation system ensure stable 24-hour uninterrupted full-load operation in high-temperature, low-temperature and dusty harsh environments.
We provide full professional technical documents, complete spare parts supply and lifelong remote technical guidance. For global super-large oilfield projects, we can arrange senior professional engineering teams for on-site installation, commissioning and exclusive operator training services.
