Rig Substructure Moving Equipment

Rig Substructure Moving Equipment is a professional heavy-load skid transfer and integral relocation solution tailor-made for the base substructure of 150HP-850HP full-series XJ truck-mounted workover rigs. As the bottom core supporting module of the full rig moving system, it targets the industry pain points of traditional substructure transportation, including split disassembly, repeated hoisting, base positioning deviation, and frame structural stress deformation. Adopting modular integral skid-mounted structure and multi-point synchronous hydraulic skidding technology, this equipment enables one-piece overall relocation of the heavy rig substructure without disassembling base frames, supporting legs, fixed locking components and pipeline systems. Fully compliant with API 4F and API 7K global petroleum machinery safety standards, it perfectly matches standard and reinforced substructure of all XJ-series workover rigs, adapting to ultra-harsh operating environments such as deserts, Gobi, mountainous terrains, muddy wetlands and high-altitude frozen plateaus. It drastically improves substructure relocation efficiency, eliminates repeated leveling and calibration after moving, reduces frame fatigue damage caused by frequent disassembly, and provides stable, low-loss and high-reliability base transfer guarantee for large-scale cluster well continuous workover and cross-region rig batch deployment projects.

Core advantages

Designed around the operating requirement.

Integral Zero-Disassembly Skid Moving Design

Abandoning conventional split transportation mode, the equipment supports complete integral moving of the whole rig substructure. All supporting legs, base crossbeams, fixed locking devices and matched hydraulic pipelines remain intact without disassembly or cutting. It saves massive post-moving assembly, leveling and calibration work, completely avoiding installation errors and structural stress deviation caused by repeated disassembly and reassembly.

Multi-Point Synchronous Hydraulic Skidding & Balanced Load

Equipped with full-frame synchronous hydraulic skidding system and intelligent load balancing adjustment module, realizing uniform stress distribution on the entire substructure frame during jacking, skidding and relocation. It effectively solves local torsion, beam bending, welding seam cracking and foundation stress unbalance problems occurring in traditional crane hoisting and segmented moving, thoroughly protecting the overall structural rigidity and installation accuracy of the heavy-duty substructure.

Full-Series Universal Adaptive Matching

Features adjustable modular positioning fixtures and flexible skid span design, fully compatible with light, medium and ultra-heavy substructure specifications of 150HP to 850HP XJ workover rigs. It can adapt to different base sizes, load grades and ground clearance parameters, realizing universal matching for the full product line with strong scalability and customized adaptability.

Super Heavy-Load Anti-Deformation Structural Performance

The main skid frame adopts thickened high-strength alloy steel integral welding and overall heat treatment process, with optimized anti-torsion, anti-bending and anti-sinking structural design. It stably bears the full dead weight and working load of ultra-heavy rig substructures, maintaining precise flatness and structural stability during long-distance bumpy transportation and frequent repeated skidding operations.

Full-Climate & All-Terrain Extreme Adaptability

The whole set of equipment adopts military-grade anti-corrosion, wear-resistant, sand-proof and low-temperature resistant coating. Core hydraulic units, locking elements and electrical components adopt world-renowned industrial-grade accessories. It supports stable operation in the range of -40℃ to +55℃, adapting to high-altitude severe cold, high-temperature drought, strong wind and sand erosion, and soft muddy road conditions, meeting year-round uninterrupted substructure moving demands of global ultra-harsh oilfields.

High-Efficiency & Low Operation Cost

Integral skid moving eliminates reliance on large-tonnage cranes and professional disassembly teams, greatly reducing auxiliary equipment input, labor cost and construction cycle. It shortens the single-rig relocation cycle by over 55%, effectively lowering long-term structural maintenance loss, and perfectly fitting high-frequency well switching and batch intensive deployment requirements of modern oilfield cluster operations.

Buyer questions

Frequently asked about this equipment.

The following questions address common equipment selection and operating considerations.

Is substructure disassembly required during moving?

No disassembly is needed. This equipment adopts professional integral skid moving design, supporting overall transfer of the complete rig substructure. All base frames, support legs and matching accessories remain intact, realizing zero-disassembly relocation, avoiding component loss and assembly precision deviation.

Which rig models and substructures are compatible?

It fully matches all 150HP-850HP XJ-series workover rigs, compatible with standard light-duty, medium-duty and ultra-heavy reinforced substructure bases. The adjustable modular design ensures full-line universal adaptability and flexible matching of different base dimensions and load grades.

Can it effectively prevent substructure deformation during relocation?

Absolutely. The multi-point synchronous jacking and balanced load structure ensures uniform stress on the entire base frame, avoiding local torsion, bending and welding deformation caused by uneven force. Double anti-vibration and locking design guarantees stable fixation during long-distance transportation, fully protecting substructure flatness and structural rigidity.

What are the advantages over traditional substructure moving methods?

Traditional solutions require segmented disassembly, repeated crane hoisting and secondary leveling calibration, featuring long cycle, high cost and easy structural damage. This integral skid moving system realizes one-piece rapid relocation with no disassembly, no calibration and low loss, greatly improving moving efficiency and reducing long-term maintenance costs.

Does intelligent monitoring and remote control support customization?

Yes. We provide personalized upgrades including intelligent load balancing correction, real-time stress and flatness monitoring, remote wireless operation and automatic fault alarm functions, realizing full-process intelligent supervision of substructure moving status and improving overall operation safety and intelligence.
