350HP Truck-Mounted Rigs

Features of 350HPTruck Mounted Workover Equipment

Applications

The 350HP truck-mounted drilling rig is engineered for medium-depth drilling and heavy workover operations. It's the workhorse of our truck-mounted rig lineup — powerful enough for most medium-depth well work, yet still mobile enough to move between well sites quickly.

- Primary use: medium-depth oil and gas well drilling, deep well workover, well testing, salvage, and pump inspection.
- Widely deployed on onshore oil fields across the Middle East, Russia, Central Asia, and Southeast Asia.
- The preferred choice for drilling contractors who need more power than the 250HP rig offers, but still want the mobility of a truck-mounted unit.

The Perfect Balance of Power and Mobility

There's a sweet spot in drilling rig selection: you need enough power to drill deeper and handle heavier workover operations, but you don't want to give up the mobility that makes truck-mounted rigs so cost-effective.

The 350HP rig hits that sweet spot. With 1,125 kN of hook load and a CAT C18 engine, it has the muscle to handle medium-depth drilling and heavy workover work. And because it's still built on a truck chassis, you retain the fast rig moves and low mobilization costs that make truck-mounted rigs so attractive.

The finite element optimized design means we've saved weight without sacrificing strength — critical when you're pushing the limits of what a truck chassis can carry. Multiple patented technologies are built into the design.

Choosing the Right Truck-Mounted Rig

For medium-depth wells (3,500m to 5,000m) or operations involving heavy workover and fishing work, the 350HP unit delivers the right balance of power and mobility.

If your wells are shallower and operations are routine, the 250HP Truck-Mounted Rig offers a more cost-effective solution. For deeper wells or heavier drilling work, step up to a 450HP Truck-Mounted Rig for even more power and capacity.

FAQs

Q: What's the maximum hook load?
A: The maximum static hook load is 1,125 kN — significantly higher than the 250HP model's capacity.

Q: What engine and transmission are used?
A: It's powered by an imported Caterpillar C18 engine paired with an Allison M6620AR transmission — both known for reliability and global service support.

Q: What chassis is used?
A: This rig is built on a 10×8 self-propelled workover rig chassis, designed to handle the weight of the taller mast and higher-capacity drawworks.

Q: What makes this rig different from smaller models?
A: It incorporates finite element analysis design, multiple patented technologies, and a 5+5R anti-reverse rotary table — features reserved for our medium-duty and larger rigs.
