At 5500 m of workover with 73 mm tubing, and 4500 m when drilling with 73 mm drill pipe, the XJ450 truck-mounted workover rig sits where shallow service rigs run out of reach and the deep fleet starts. Its hoisting train is rated 1125 kN maximum, strung 4x5 on 26 mm wire line under a 32 m mast proofed to 1200 kN static. A single CAT C15 rated 540 bhp drives through an Allison M5620AR transmission to a drawworks that pulls 180 kN on the second floor at up to 450 rpm. That mechanical package is paired with a ZP175 rotary table and a drilling floor selectable at 3.5 m, 4 m or 4.5 m, so the same carrier can run completion tubing, drill pipe and casing rather than being locked to one string. Mounted and self-propelled, it relocates between cluster wells as one vehicle, which is why service companies choose it for medium-deep overhaul and slim-hole campaigns instead of mobilizing a larger skid rig.
Rated for 5500 m of 73 mm tubing on workover and 4500 m of 73 mm drill pipe on drilling, the rig covers the medium-deep band that the 250 hp and 350 hp class cannot reach without moving to a much larger machine.
The hoisting system is rated to 1125 kN maximum, reeved 4x5 with 26 mm wire line, leaving enough pull reserve for stuck tubing and heavy completion jobs without oversizing the whole carrier.
One 540 bhp CAT C15 feeds an Allison M5620AR gearbox to the drawworks, whose second-floor fast line pulls 180 kN at up to 450 rpm, a simple mechanical path that field crews already maintain.
The mast cleans 32 m and carries 1200 kN of static load, long enough for stand-based tripping and stiff enough for the tubular strings run on 5500 m service.
A ZP175 rotary table plus a drilling floor chosen at 3.5 m, 4 m or 4.5 m lets the deck match blowout-preventer and casing height, turning the unit from pure workover into slim-hole drilling service.
Mast, drawworks, rotary table and floor ride on the carrier as one load, so a group of medium-deep wells is worked by driving between locations instead of breaking down and re-erecting a spread.

Buyers comparing the 450HP truck-mounted rig with the 250HP and 350HP classes usually ask about depth and chassis reach.
Against the XJ250 and XJ350, the XJ450 moves the envelope from shallow into medium-deep service: workover depth reaches 5500 m on 73 mm tubing and 4500 m on 73 mm drill pipe, the hoisting train is rated 1125 kN maximum strung 4×5 on 26 mm wire line, and the 32 m mast is proofed to 1200 kN static. The CAT C15 at 540 bhp through an Allison M5620AR provides the torque reserve the smaller rigs run out of on high-resistance strings, so the XJ450 is the first truck-mounted step that keeps hook and mast margin for wells beyond 4000 m.
No. With the mast folded and the outriggers retracted, the XJ450 drives between wells under its own power, so a trailer or crane is not needed for routine moves; the self-propelled carrier is part of the unit rather than a separate transport spread.
The standard model adapts to -20℃ to +55℃ working environment. We can provide customized low-temperature start-up reinforcement and high-temperature dust-proof heat dissipation upgrades according to customer regional working conditions to meet extreme climate operation needs.
Yes. We can adjust key parameters such as hook load, lifting stroke and power matching according to customers' actual well depth, downhole working conditions and project requirements, and provide one-to-one customized technical solutions.
We provide complete official operation manuals, spare parts catalogs and remote real-time technical guidance. Overseas on-site installation, commissioning and operator training services can be arranged according to project needs.
Commercial terms are confirmed in the quotation for the exact configuration, quantity and destination.
Optimized for long-cycle heavy-load working conditions, the rig fully complies with API and international petroleum machinery standards, serving large-scale oil and gas field workover, medium-deep drilling, geothermal well development and other high-demand fields. The derrick is load-tested to its rated hook load at the Jingzhou plant under ISO 9001:2015 quality management, and the full rig runs through a factory acceptance test before shipment.
Operation manuals, chassis documentation and factory test reports are supplied; the PTO and hydraulic system schematics are included for the client's service department. On-site commissioning is available.

Workover to 3200 m on 2 7/8-inch upset tubing is this rig's job: a 400 kN nominal hook load that peaks at 675 kN, run through six lines of 22 mm wire under a mast that stands 21 m or 23.5 m.
Badged ZYT5502TZJ, this rig is defined by a 1125 kN maximum load on a 4x5 traveling system, eight lines of 26 mm (1-inch) wire pulled to a 210 kN fast-line pull, under a 32 m clearance mast.
Built for wells the shallow and mid rigs cannot reach, this 550 hp unit carries its rated 550 hp power pack on a multi-axle heavy off-road carrier and is rated for typical workover to 5800 m and service to 7000 m.
