220 to 390 t skid capacity for the base block
The skidding frame is rated to 220 to 390 tonnes, carrying the heavy base substructure as one block rather than hoisting it in pieces with a crane.
Rig Moving Systems
Rig Substructure Moving Equipment
The rig substructure is the bottom 180 to 330 tonne block of the rig, and this skid mover is rated to shift it at 220 to 390 tonnes capacity, 10 km per hour, with 600 mm clearance on a 12,000 mm road width. Supporting legs, base crossbeams, locks and the connected hydraulic piping stay assembled through the move, so the substructure lands at the next well slot level and flat, with no secondary leveling crew. Between the mast mover's 100 to 180 tonne rating and the whole-rig carrier's 400 to 540 tonne envelope, this unit owns the base: heavy, wide and rigid, where beam twist and foundation stress are the failure modes the multi-point skidding is designed to control. It serves the standard and reinforced substructures of the 150 to 850 hp XJ workover range across -17 to 55 degree sites.
Core advantages
Designed around the operating requirement.
180 to 330 t substructure weight
It moves 180 to 330 tonne rig substructures, both standard and reinforced, with adjustable fixtures set to the base size and load grade at order time.
Multi-point skidding keeps legs assembled
Multi-point hydraulic skidding lifts and shifts the substructure with supporting legs, crossbeams and locks still fitted, so the base lands level and needs no post-move re-leveling crew.
12 m road width, 600 mm clearance
A 12,000 mm road-width allowance and 600 mm clearance set the wide, low route the rigid base block requires, matching the whole-rig carrier rather than the narrower mast and auxiliary units.
10 km/h shift, lands level
The base shifts at up to 10 km per hour, controlled by closed-loop hydraulic walking so the heavy block tracks straight and settles flat at the next slot.
Anti-torsion frame protects beam flatness
The thickened alloy-steel skid frame, stress-relief welded, resists torsion and bending under the substructure load, holding beam flatness through repeated skidding cycles.

Application
Where this equipment is used.
- Moving the 180–330 tonne rig substructure on the 220–390 tonne rated skid mover, at up to 10 km/h with 600 mm clearance.
- Integral transfer of the substructure with legs, base crossbeams, locks and hydraulic piping assembled, landing level at the next slot.
- Frequent base relocation between wells in hilly or mountainous blocks where beam twist and foundation stress must be controlled.
- Low-loss precision moving of heavy substructures for 650–850 HP rig classes and ultra-deep programmes.
- Batch skid-moving and standardised deployment of several rig bases within one block.
- Rapid base shifting during emergency mobilisation across desert, Gobi and high-altitude sites.

- Monitoring: substructure stress, horizontal flatness and hydraulic pressure monitored during the move.
Buyer questions
Frequently asked about this equipment.
What buyers check on the substructure moving equipment: the 180-330 t base range and the 220-390 t moving capacity.
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?
Yes. The mover keeps the substructure supported at multiple jacking points through the move, so the 180–330 tonne base block travels as a rigid assembly with legs, base crossbeams and hydraulic piping still connected. Rated 220–390 tonnes at up to 10 km/h with 600 mm clearance, it lands the substructure level and flat at the next well slot, which is what controls beam twist and foundation stress on the move.
What are the advantages over traditional substructure moving methods?
A traditional move splits the substructure, lifts each section with crane and re-levels the base on arrival, which adds crane days and risks bending the base beams. This skid mover shifts the 180 to 330 tonne substructure as one block on its 220 to 390 tonne frame, at up to 10 km/h, with legs, crossbeams and locks still fitted. The base lands level at the next slot, so no second leveling crew and no beam re-alignment follow the move.
Does intelligent monitoring and remote control support customization?
Monitoring options are tailored to the base block: load-balancing correction across the 220 to 390 tonne skidding path, real-time stress and flatness readout on the substructure frame, and remote wireless operation from a safe stand-off during the 10 km per hour shift. Because the substructure moves on 12,000 mm routes with 600 mm clearance, automatic fault alarm on the hydraulic locks and beam-deviation monitoring can be added at order time to protect the 180 to 330 tonne base from torsion during well-to-well moves.
