WG-90 Excavation and Hydraulic Drilling Rig: Making Construction Work Easier

2025,09,17

What is the WG-90?

The WG-90 is a top-of-the-line excavator that also works as a Drilling Rig. ANNENG built it to do both jobs well—no more switching between separate machines.

Instead of just adding a drill to an excavator, we integrated the drilling parts right into the original hydraulic system. This means it digs and drills smoothly, saving you time and space on the job site. Contractors around the world use it because it works well in all kinds of conditions.

What Makes It Special?

Two Machines in One

The WG-90 starts as an excavator but adds drilling power—no loss in how well it digs. This one machine replaces two, saving you up to 30% on equipment costs.

Efficient Hydraulics

The hydraulic system is built to work smoothly, even in tough ground. It uses power well, so parts last longer and you spend less on repairs.

Tough Build

Important parts like the drill mast are made from strong alloy steel. The frame is reinforced to handle heavy loads and shaking, so it stays steady while drilling.

Easy Controls

The control panel has digital screens that show what the drill is doing in real time. It’s simple to use, so operators learn fast and make fewer mistakes.

Quick Attachment Swaps

You can switch between digging and drilling tools in under 30 minutes. This means less downtime and more work done each day.

How to Use the WG-90

Before You Start
- Check oil, hydraulic fluid, and coolant levels
- Look at drill bits—replace if they’re worn or broken
- Make sure safety guards and emergency stops work
- Check hydraulic hoses for leaks or damage
Setting Up
- Park on flat ground and set the parking brake
- Extend stabilizers to keep the machine steady
- Put on the right drill bit for the job
- Adjust the mast angle to where you need it
Drilling
- Start the engine and let it warm up
- Lower the drill bit to where you want to start
- Turn on rotation and feeding at the recommended settings
- Watch how it’s drilling—change pressure if the ground is harder or softer
- Pull the drill out sometimes to clear dirt and prevent jams
After You’re Done
- Bring the drill bit up and move the mast back for transport
- Clean the drill parts and clear debris from the area
- Retract stabilizers so you can move the machine
- Write down how long you used it and any issues in the log
- Give it a quick clean to stop dirt building up

Note: Always check the operator’s manual for full safety steps and maintenance tips.

Where It Works

Solar Farms: Great for drilling holes for solar panel foundations
Mines: Good for exploring and making blast holes in surface mines
Building Sites: Perfect for starting holes for building foundations
Road Work: Useful for soil tests, rock drilling, and road sign bases
Quarries: Works well for drilling holes to get stone out
Geothermal Projects: Good for shallow wells for heating systems
Land Development: Helps with site prep, like soil testing and stabilizing ground

What You Get Out of It

Spend Less on Equipment: One machine does two jobs—no need for separate excavators and drills
Get More Done: Quick tool swaps mean less downtime—you can boost daily work by up to 40%
Lower Costs to Run: Uses less fuel and needs less maintenance than two machines
Works for Many Jobs: Adapts to different sites, so you use it more across projects
Safer to Use: Stable and has good safety features, so fewer accidents
Good Investment: It’s built to last, so you get your money back fast
Easier to Move: Transport one machine instead of two—saves on delivery costs

Certifications

The WG-90 meets global standards, so you can use it anywhere safely:

ISO 9001:2015 (Quality Management)
CE Certification (for Europe)
ANSI/SAE J1113 (Safety Standards)
EU Stage V (Emission Standards)
EPA Tier 4 Final (Emissions for the US)
ISO 14001 (Environmental Management)

These certifications make it easy to import and use in most countries.

We Can Customize It

Special filters for dusty places

Our engineers will work with you to make sure it fits your unique jobs.

How We Build the WG-90

Every WG-90 goes through 10 steps to make sure it’s top quality. We mix old-fashioned care with new technology:

Design & Planning: Our engineers start with 3D scans of the base excavator. They make custom plans and run computer tests to see how it holds up after 10,000+ drills.
Parts Checking: Important parts get checked three times—once by the supplier, once by our team, and once by outside auditors. Hydraulic parts get pressure-tested at 150% of normal for 3 days straight.
Reinforcing the Frame: We add strong steel plates to the excavator’s frame. Robots weld them with 0.01mm accuracy. Each weld gets checked with sound waves to find hidden flaws.
Adding Hydraulics: We install custom parts to create separate hydraulic systems for digging and drilling. This makes it easy to fix and upgrade later.
Building the Drill Mast: We cut and bend strong steel plates to make the mast. Then we heat-treat it for 48 hours to stop it from warping when in use.
Setting Up Controls: Each machine gets a custom computer module that adjusts hydraulic flow for different drilling conditions. It’s like a "personality" for the machine to work best on your jobs.
Putting It All Together: Parts are assembled step by step, with 17 quality checks along the way. Each station specializes in one part—hydraulics, electricity, or structure—to make sure it’s done right.
Testing in Extreme Conditions: Finished machines go into a climate chamber for 10 hours. We test them from -20°C to 50°C to make sure they work in any weather.
Field Testing: Every WG-90 drills 50 test holes at our site. We have concrete, sand, and solid rock areas to check how it works on different ground.
Packing & Paperwork: Each machine gets a book with part numbers, test results, and settings. We pack it for shipping with humidity controls and shock monitors to keep it safe.

Each WG-90 takes about 45 days to build—we don’t rush. This careful process means 98.7% of machines pass all tests on the first try, which is way better than most in the industry.

What Customers Say

Michael Thompson, Operations Director, Global Construction Ltd.

"The WG-90 changed how we do solar farm projects. It drills better than dedicated machines and still digs, saving time on site prep. We’ve cut our equipment fleet by 3 machines since we got it."

Sophia Rodriguez, Procurement Manager, Andes Mining Group

"We weren’t sure about an excavator that also drills, but the WG-90 is great for our mines. It still works as a top excavator and adds precise drilling. Our operators like how easy it is to use."

David Chen, Project Manager, Eastern Infrastructure

"We were skeptical about an excavator-drill combo, but the WG-90 proves itself daily on our road jobs. It digs and drills equally well, and switching tools quickly keeps us on schedule."

Common Questions

How much fuel does the WG-90 save compared to using separate machines?

You’ll use 22-28% less fuel with the WG-90 than running a separate excavator and drilling rig. Customers tell us they save about 4.3 gallons per hour when doing both jobs.

How much training do operators need to switch between functions?

We recommend a 16-hour course: 8 hours in a classroom learning about the hydraulic differences, and 8 hours practicing with a certified trainer. Operators need to show they can do both jobs well before getting certified.

Can it use drill bits from other brands?

Yes, the adapter works with most standard drill bits. We’ll give you a guide to which brands and models fit. If you need a special adapter, we can make one for you.

How long do key parts like the drill mast and hydraulic hoses last?

With proper care, the drill mast lasts 8,000+ hours. Hydraulic hoses can go 3,000 hours, but we suggest replacing them every 2,500 hours to avoid unexpected breakdowns.

Is it easy to transport between job sites?

Yes, when set up for transport, it’s the same size as a standard excavator. It fits on a regular lowboy trailer and usually doesn’t need oversize permits. We’ll give you exact dimensions and weight info for safe loading.

Can you help fix problems remotely?

All WG-90s have systems for remote checks. Our tech team can see real-time data, run tests, and help fix 85% of common issues without coming to your site.

Do you offer financing for international buyers?

Yes, we work with partners to offer flexible plans—36-60 month terms with good rates for qualified buyers. We also team up with export credit agencies in major markets to get you better financing.
