4. The truck mounted drill rigs adopt 5+5R anti-reverse rotary table transmission device.
5. Parallelogram substructure of mobile workover euipment has stable structure and is easy to install.
Applications
The 750HP truck-mounted drilling rig is our most powerful mobile drilling rig — engineered for ultra-deep well operations and the most demanding drilling work. It represents the upper limit of what a truck-mounted drilling rig can achieve.
- Primary use: ultra-deep well drilling, heavy workover operations, well testing, salvage, and pump inspection on the deepest oil fields.
- Built for the largest drilling contractors operating on major deep onshore oil fields across the Middle East, Russia, and Central Asia.
- The rig you deploy when even the 650HP model doesn't have enough power, but you still need the mobility of a truck-mounted unit.
The Ultimate Mobile Drilling Rig
When you reach the 750HP class, you're at the absolute pinnacle of what a truck-mounted drilling rig can do. Beyond this point, you're looking at skid-mounted drilling rigs that require weeks to rig up and move between locations.
What makes this rig possible is the double-engine compound power system. Two CAT C18 engines working together deliver the massive horsepower needed for ultra-deep drilling — while providing redundancy for continuous operation. If one engine needs service, you can keep working on the other.
With 1,800 kN of hook load and a 14×8 chassis, this rig gives you skid-rig-level drilling power with workover-rig-level mobility. It's the difference between mobilizing a full drilling rig (weeks, huge cost) and mobilizing a mobile drilling rig (hours, a fraction of the cost).
Choosing the Right Truck-Mounted Rig
For ultra-deep wells (7,000m+) or operations involving the heaviest drilling and workover work, the 750HP unit delivers maximum power in a mobile package.
If your wells are shallower and operations are less demanding, the 650HP 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's power system unique?
A: It uses a mature double-engine compound power system with two CAT C18 engines and two Allison transmissions — delivering massive horsepower while providing redundancy for continuous operation.
Q: What's the maximum hook load?
A: The maximum static hook load is 1,800 kN — one of the highest ratings for any self-propelled drilling rig in China.
Q: What chassis is used?
A: This rig is built on a 14×8 heavy-duty workover rig chassis — the largest chassis we use for truck-mounted drilling rigs.
Q: How does this compare to smaller models?
A: The 750HP class is the pinnacle of mobile drilling rigs. It offers near-skid-rig-level power with truck-rig-level mobility — for the deepest, most demanding well drilling projects.

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.
