5. Parallelogram substructure has stable structure and is easy to install.
Applications
The 850HP truck-mounted drilling rig is our flagship mobile drilling rig — the maximum grade self-propelled drilling rig in China. It's engineered for the deepest, most challenging well drilling operations where nothing less than the maximum in mobile rig power will do.
- Primary use: ultra-deep well drilling, heavy workover operations, well testing, salvage, and pump inspection on the deepest major oil fields.
- Built for the largest drilling contractors operating on the most challenging onshore oil fields across the Middle East, Russia, and Central Asia.
- The rig you deploy when you need skid-rig-level drilling power, but you still want the mobility and fast rig-up times of a truck-mounted unit.
The Ultimate Mobile Drilling Solution
The 850HP rig is the absolute pinnacle of truck-mounted drilling rig engineering. With 2,250 kN of hook load and a 14×10/14×12 chassis, it delivers drilling-rig-level performance in a mobile package.
What makes this rig truly special is its flexibility. The double-engine compound power system lets you run on a single engine for lighter duty work — saving fuel and reducing wear — or both engines for maximum power when you need it. It's like having two rigs in one.
And because it's still a truck-mounted unit, you retain the mobility that makes mobile rigs so cost-effective. You get skid-rig-level power without the weeks of rig-up time and huge mobilization costs that come with a full drilling rig. This is the future of onshore drilling — maximum power, maximum mobility.
Choosing the Right Truck-Mounted Rig
For the deepest wells (8,000m+) or operations involving the heaviest drilling and completion work, the 850HP unit delivers the maximum power available in a truck-mounted drilling rig.
If your wells are shallower and operations are less demanding, the 750HP Truck-Mounted Rig offers a more cost-effective solution. For even deeper drilling work beyond what this flagship mobile rig can handle, you'll need to move up to our skid-mounted drilling rigs.
FAQs
Q: What makes this rig the maximum grade self-propelled drilling rig in China?
A: It has the highest hook load (2,250 kN), largest chassis (14×10/14×12), and most powerful dual-engine system — representing the absolute pinnacle of truck-mounted drilling rig engineering.
Q: What's the maximum hook load?
A: The maximum static hook load is 2,250 kN — the highest rating for any self-propelled drilling rig in China.
Q: Can it run on a single engine?
A: Yes. The double-engine compound power system can operate on single engine for lighter duty work, or dual engines for maximum power — giving you both flexibility and redundancy.
Q: How does this compare to a skid-mounted rig?
A: This rig delivers near-skid-rig-level power, but with the mobility and fast rig-up times of a truck-mounted unit. You get the best of both worlds — maximum power without the weeks of rig-up time.

Fast Mobilization for Multi-Well Pads
A hp truck-mounted rig is built for fields with scattered wells, where non-productive time between wells cuts heavily into operation margins. The integrated truck chassis means the rig can drive directly between well sites without needing disassembly or separate heavy haul trucks.
When moving between pads on the same field, a standard rig-up takes about , including extending the outriggers, raising the mast, and pressure-testing the circulation system. For most onshore fields, transport dimensions are , which means crews can plan daily moves without waiting for road permits or closing public roads.
The rig is rated for drilling depths up to meters, which covers the majority of shallow to medium-depth development wells in most onshore oil fields. This makes it a cost-effective choice for workover campaigns and infill drilling where the rig needs to move to a new location every few days.
FAQs
Q: What is the pulling capacity of the hoisting system?
A: This mid-size truck rig is rated for hook loads up to 135 tons, which covers most medium-depth well servicing and drilling work.
Q: Can the derrick be operated in high wind conditions?
A: The derrick has a rated wind speed for drilling operations and a survival wind speed when in the parked position, as detailed in the operation manual.
Q: Do you supply the complete rig ready to drive on the highway?
A: Yes, we supply the complete rig as a road-legal truck unit, with all lighting, mirrors, and safety equipment required for on-road transport.
