675kN hook, six-line purchase
Hook load is 400kN nominal and 675kN maximum on a φ22mm wire rope reeved over six lines, enough headroom for casing repair and heavy paraffin jobs that exceed the 150 class.
Workover Rigs
250HP Workover Rig (XJ250)
The XJ250 is the first truck in the fleet where hoisting speed starts to matter: a 675kN maximum hook on a φ22mm, six-line train runs the hook at up to 1.5 m/s, pulling 3200m of 2 7/8″ upset tubing in less time than a slower light rig. The 400kN nominal hook and a 21m or 23.5m mast cover medium-shallow overhaul and tripping that the 150 class cannot, without stepping up to a 10×8 carrier. The 250hp power pack turns through a torque-converter transmission, and at a 31,490kg curb weight the rig still relocates as one vehicle on a 6×4, with 6×6 drive available for looser ground. It is the unit operators reach for when a well needs casing work or heavy paraffin but the location cannot justify a heavy-duty spread.
Core advantages
Designed around the operating requirement.
1.5 m/s hook hoisting speed
The drawworks cycles the hook at up to 1.5 m/s, so tripping 3200m of 2 7/8″ upset tubing is faster than on lighter 150hp rigs, cutting rig-time per well on cluster programs.
Choice of 21m or 23.5m mast
Buyers pick a 21m or a 23.5m lattice mast according to stand length and wellhead height; the taller option racks more per stand when spacing out a medium-depth block.
6×4 or 6×6 self-propelled carrier
A 6×4 drive handles sealed roads and prepared locations, while the optional 6×6 adds traction for muddy or gravel-pad sites; either way the rig relocates as one integral load.
31,490kg, sized for medium pads
At 31,490kg the whole set, mast and drawworks included, stays below the heavy-axle limits that gate a 10×8 rig, reaching medium-shallow locations with ordinary permitting.
250hp drive with torque reserve
A 250hp diesel drives through a torque-converter transmission that keeps the drawworks in its pulling band as hook load rises, avoiding the lag of a direct-drive light rig on stuck tubing.

Application
Where this equipment is used.
- Medium-shallow overhaul and tripping to 3200 m of 2 7/8 in upset tubing, where the 400 kN nominal / 675 kN maximum hook and 1.5 m/s hoisting speed keep trips moving.
- Casing work, heavy paraffin removal and stuck-pipe jobs that the 150 hp class cannot carry, without stepping up to a 10×8 carrier.
- Frequent relocation across scattered well clusters: the 31,490 kg unit moves as one vehicle on the 6×4 chassis, with 6×6 for looser ground.
- Routine maintenance and reservoir-protection cycles on mature medium-shallow blocks where cycle time decides the cost.
- Well service on hilly and low-altitude terrain where the 21 m or 23.5 m mast clears the standing equipment.

Buyer questions
Frequently asked about this equipment.
Buyers evaluating the XJ250 usually ask about its 3,200 m workover depth, 675 kN hook and 1.5 m/s hoisting speed.
What are the core advantages of 250HP XJ250 workover rig compared with 150HP model?
The XJ250 is where the 150hp class runs out of headroom: a 675kN maximum hook on a φ22mm six-line train and 1.5 m/s hoisting speed carry 2 7/8″ upset tubing to the 3200m rated workover depth, clearing heavy paraffin and casing jobs in fewer trips. Routine overhaul runs inside the 400kN nominal hook, and the 250hp torque-converter drive keeps the block moving as load climbs. For a block already running 150hp rigs, the XJ250 steps up without the permitting weight of a 10×8 carrier.
Does this rig support frequent cross-site relocation?
Yes. The XJ250 travels as one 31,490kg load on its 6×4 chassis, mast and drawworks included, so a move needs no separate mast truck or crane. With 6×6 drive optional for muddy or gravel-pad locations, the rig clears one well site and rigs up at the next within the same program.
What is the maximum working depth of the XJ250 workover rig?
On 2 7/8″ upset tubing the rated workover depth is 3200m, bounded by the 400kN nominal and 675kN maximum hook loads and the φ22mm six-line hoist. The mast, 21m or 23.5m, is chosen to match the string; for a shorter or heavier program the hoisting parameters are adjusted at order and the verified limits written into the test report.
What working conditions is this rig suitable for?
The XJ250 fits medium-shallow blocks where wells need casing repair, heavy paraffin removal or stuck-pipe work beyond the 150hp class, at rated depths to 3200m on 2 7/8″ upset tubing. It also covers routine flushing and maintenance between overhauls, and because the whole unit relocates on one chassis it suits operators running several scattered well clusters from one spread.
What after-sales services are provided for the XJ250 workover rig?
Documentation ships complete: operation and maintenance manuals, a factory test report, and a first-period spare list covering the φ22mm wire rope, transmission filters and chassis wear parts. Remote technical guidance is free for the life of the rig. On-site commissioning and a structured operator training session are arranged for the first deployment of a medium-shallow well block.
