1470 kN hook rating
The 1470 kN maximum load steps clear of the 1125 kN class, leaving working margin for overhauls where long, heavy tubing strings and stuck-pipe pulls define the job.
Drilling Rigs
650HP Truck Mounted Rigs
Rated to 1470 kN maximum hook load, the 650 hp truck-mounted workover rig is the machine a service fleet steps up to when 1125 kN-class units start giving away margin on heavy overhaul. It runs eight lines of 29 mm (1 1/8-inch) drill wire in a 4x5 arrangement under a 35 m clearance mast, with a fast-line pull of 210 kN. Power comes from a single CAT C18 driving through an Allison M6620AR transmission, and the rig drills to 2000 m on 4 1/2-inch drill pipe while carrying the hook load for deeper workover strings. That combination, a heavier line, a taller mast and a C18 drivetrain, is aimed at long-cycle heavy pulls on deeper land wells, before a dual-engine unit becomes the necessary choice.
Core advantages
Designed around the operating requirement.
29 mm line on eight lines, 4x5
Eight lines of 29 mm drill wire reeved 4x5 carry the hoisting load to a 210 kN fast-line pull, thicker line than the medium rigs use, which cuts wire fatigue on repetitive heavy trips.
CAT C18 with Allison M6620AR
A single CAT C18 through an Allison M6620AR transmission supplies the torque for 2000 m of 4 1/2-inch pipe drilling and the sustained pulls of deep workover, without the complexity of a second power pack.
35 m clearance mast
The 35 m mast clears longer stands than the 32 m class, shortening each trip when running and pulling the tubulars that deep-well overhaul demands.
1.4 m/s hoisting cadence
A 1.4 m/s maximum hoisting speed keeps trips moving on heavy strings, balancing pull force against cycle time on long workover programs.
Built for heavy-overhaul cycles
The hoisting and structural package is sized for repeated high-load pulls rather than occasional peak demand, which is what separates it from a medium rig asked to work above its rating.

Application
Where this equipment is used.
- This truck-mounted workover rig takes heavy overhaul and deep workover where the 1125 kN class runs out of margin: a 1470 kN maximum hook on eight lines of 29 mm wire in a 4×5 arrangement.
- Drilling to 2000 m on 4-1/2 in drill pipe plus deeper workover strings on the same self-propelled carrier.
- Long-cycle heavy pulls on deeper land wells sustained by the single CAT C18 / Allison M6620AR drivetrain.
- Frequent relocation between deep-well clusters: the carrier moves as one vehicle without trailers.
- Well service where the 35 m mast gives headroom for long stands and a stacked BOP.

Options for a matched equipment scope.
Available configurations can be matched to the equipment model, operating conditions and project requirements.
- Hook and hoist margin: set the 1470 kN maximum rating, 4×5, Φ29 mm arrangement and 35 m mast against the planned strings.
- Drilling scope: confirm the 2000 m drilling rating and circulating package if the rig will drill before workover.
- Power train: CAT C18 / Allison M6620AR is the reference; a dual-engine option can be discussed for heavier duty.
- Well-control fit: BOP height, choke manifold and floor layout matched to the 35 m mast clearance.
- Winter and heat provisions on 650HP Truck Mounted Rigs: low-temperature start, heat preservation and coating matched to the region.
- Paperwork and training for 650HP Truck Mounted Rigs: manuals, factory test report and first-period spares ship with the unit; commissioning and familiarization on request.
Buyer questions
Frequently asked about this equipment.
What buyers check on the 650HP rigs: long-cycle heavy pulls, line count and the C18 drivetrain choice.
What are the core advantages of the 650HP truck-mounted workover rig compared with 450HP/550HP models?
The XJ650 is the step after the 450HP and 550HP classes for heavy overhaul: 1470 kN maximum hook load on an eight-line, 4×5 arrangement of 29 mm (1 1/8″) wire under a 35 m clearance mast, with a 210 kN fast-line pull. The single CAT C18 behind the Allison M6620AR holds the torque for long-cycle heavy pulling, and the rig separately drills to 2000 m on 4 1/2″ pipe, which is the load and mast margin the 1125 kN class starts to give away.
Does the 650HP XJ650 rig need auxiliary transportation equipment?
No. Once the mast is lowered and outriggers stowed, the XJ650 travels under its own power as one road unit, so auxiliary transport is only considered for unusual loads or long inter-field moves; the self-propelled layout removes the crane and trailer cost from routine relocation.
Can this rig adapt to extreme ultra-deep well complex working conditions?
The package that handles the deep conditions is concrete: the 35 m mast clears long stands, the eight-line 4×5 arrangement with 29 mm wire carries the heavy string, and the C18/M6620AR drivetrain holds steady output for long pulls. Cold-start, dust and heat-exchanger options are configured to the site climate at order time, so state the operating region and the downhole work when requesting the quotation.
Is professional customized support available for special oilfield projects?
Yes. Configuration changes are handled at order time: hook rating, line arrangement and mast height are set against the target well, the C18/M6620AR drivetrain and 35 m mast can be matched to regional safety and environmental requirements, and the documentation set is adjusted to the project standards. State the well depth, the intervention task and the applicable standards in the inquiry so the matched configuration is quoted rather than a generic list.
What after-sales services are provided for high-horsepower heavy-duty rigs?
Each unit ships with operation and maintenance manuals, a spare-parts list and remote technical guidance. On-site installation, commissioning and operator training can be arranged for overseas projects, and because the C18/M6620AR drivetrain is standard across the heavy fleet, spares follow one catalog.
