In terms of accessories, you get a set of drill rods and a standard soil sampling attachment as noted in the included components. The hydraulic power pack is integrated into the frame. The packaging itself was robust, with heavy-duty wood framing and steel banding, which protected the machine from damage during transit. Build quality upon unboxing was immediately impressive, with thick steel plates and robust hydraulic hoses. There were no missing parts or damaged components in our unit. However, you will need to purchase specific drill bits for different soil types, as these are not standard inclusions.

How to Use Portable Crawler Water Well Drilling Rig Machine for Borehole & Soil Sampling: Complete Guide

Step 1: Initial Setup and Installation

First, place the rig on level ground. Connect the 380V power supply to the main control panel. The cable must be heavy-duty to handle the drill’s startup current. Check the hydraulic fluid level in the tank and top it off with the recommended grade. Bleed the hydraulic lines if this is a first-time startup.

Step 2: First-Time User Guide

Turn on the main power switch. Familiarize yourself with the control levers. The left joystick controls the crawler tracks for movement. The right joystick controls the drill head rotation and feed rate. Start the hydraulic pump and let it idle for two minutes to warm up the fluid.

Step 3: Core Functions and Daily Use

For soil sampling, attach the core barrel bit. Lower the drill head to the ground. Engage the rotation at a low speed of 66 rpm initially. Activate the feed mechanism. For deeper well drilling, add the 6.6 m rod sections. Monitor the penetration rate and adjust the swing torque up to 9000 N·m for hard rock.

Step 4: Advanced Techniques

To maximize drilling speed, use the 24-ton lift function to periodically raise and drop the drill string to break up compacted materials. This “hammering” effect can increase penetration in clay. Use the crawler system to reposition the rig without disassembling the mast.

Step 5: Maintenance and Care

After each shift, clean the crawler tracks of mud and debris. Lubricate all pivot points with grease. Check the hydraulic oil filter monthly. Drain and replace the hydraulic fluid every 500 hours of operation.

Step 6: Troubleshooting Common Issues

If the drill rotates slowly, check for air in the hydraulic lines. If the tracks are slipping, tighten the track tension bolts. For vibration issues, ensure the mast is pinned correctly to the chassis. This portable crawler borehole drilling rig pros cons guide helps you understand the routine.

Performance & Real-World Testing

Testing Methodology

We operated this rig over a four-week period on a farm property with mixed soil conditions. This location included topsoil, clay layers, gravel beds, and a sandstone base. We performed ten test bores ranging from 20 meters to 80 meters deep.

Performance Metrics

The penetration efficiency averaged around 20 meters per hour in clay and about 10 meters per hour in the sandstone. The swing torque was more than adequate to rotate the string without stalling. The 24-ton lifting force never felt strained.

Real-World Scenarios

On steep, muddy slopes, the crawler tracks provided excellent traction. We tested it on a 15-degree incline with wet grass, and it did not slip. The drill rig also worked well in a fenced-in area where a truck-mounted unit would not fit.

Claims vs. Reality

The manufacturer claims a 300-meter depth. While we did not test to that extreme depth, the hydraulic power and feed system showed no signs of limitation at 80 meters. The claim of 35 m/h is accurate for soft soil but unrealistic for hard rock. In our extensive use, this portable crawler borehole drilling rig passed all reliability checks.

Expert Tips for Maximum Value

Tip #1: Optimize Your Drill Bit Selection

Always match the drill bit to the soil. Use a tricone bit for rock and a drag bit for clay to maximize penetration speed.

Tip #2: Maintain Hydraulic Fluid Purity

This rig is hydraulic-dependent. Use a high-quality filter and change the oil on schedule to avoid costly pump repairs.

Tip #3: Use a Dedicated Generator Unit

Invest in a quality three-phase diesel generator. Do not try to run this on an underpowered portable generator. This portable crawler borehole drilling rig needs consistent power.

Tip #4: Practice Crawler Navigation

Spend an hour driving the rig in an open field. The track steering takes practice, but once mastered, you can position the mast exactly where needed.

Tip #5: Lubricate Threads on Drill Rods

Apply thread compound to every rod joint. It prevents the rods from seizing during deep withdrawal.

Tip #6: Monitor the Swing Torque Gauge

Keep the torque below peak levels for normal drilling. Only use full 9000 N·m for the hardest rock to reduce wear.

Common Mistakes to Avoid

Mistake: Overloading the mast by pulling too hard. Solution: Use the 24-ton lift only when necessary. Stagger the pull with rotation.
Mistake: Forgetting to lock the mast pins before drilling. Solution: Double-check all locking mechanisms after repositioning the rig.
Mistake: Drilling with a dull bit. Solution: Replace or sharpen bits after every 50 meters of hole in abrasive soil.
Mistake: Ignoring track tension. Solution: If the tracks look loose or walk off the wheels, tighten them immediately.
Mistake: Operating without coolant for the bit. Solution: Always use a water swivel to pump water down the hole to cool and flush the bit.
