Rotary drilling equipment for a 13 m pile foundation should be selected against the planned bore depth and diameter, ground conditions, site access and the hydraulic working setup. The YG-13 specifications below describe this page’s machine; deeper rotary rigs are a separate selection. Before requesting a configuration, share the pile schedule, ground report, working platform limits and transport route so the machine can be matched to the actual foundation task.

What Is Rotary Drilling Equipment?
Rotary Drilling Equipment is a machine that uses a rotating drill bit and high torque to bore deep holes for piles. It works well in soil, clay, sand, and soft rock.
Main Components of a Rotary Drilling Rig
- Drill mast: supports the drilling tool firmly
- Rotary drive: provides steady torque
- Drill bit or auger: cuts and collects soil
- Kelly bar: transmits torque and crowd force
- Hydraulic system: powers all movements
- Chassis: allows easy mobility on site
Working Principle
The rotary drilling rig runs on hydraulic power. First, the engine drives the gear pump. Then, the pump supplies oil to the rotary drive and cylinders. Next, the rotary drive spins the Kelly bar and drill bit. At the same time, the crowd system pushes the bit downward. So, the bit cuts into the ground. Soil moves into the auger flights. After that, the machine lifts the auger and empties the spoil. This cycle repeats until the target depth is reached. The whole process is clean, quick, and accurate. You can adjust speed and pressure for different ground conditions.
Working Process of a Rotary Drilling Rig Machine
Follow these typical steps to get a high-quality pile:
- Position the rig over the marked drill point.
- Set the mast to vertical and lock it securely.
- Lower the Kelly bar with the auger attached.
- Start the rotary drive and apply downward pressure.
- Drill to the design depth while watching the torque.
- Raise the auger when it becomes full of soil.
- Swing the rig and spin the auger to empty the spoil.
- Repeat the cycle until the hole reaches the required depth.
- Remove the auger and place the reinforcement cage inside.
- Pour concrete to form the solid pile foundation.
This sequence keeps the site clean and the pile quality high.
Main Advantages of a Rotary Piling Machine
Why do contractors choose this rotary drilling equipment? Here are the key reasons:
- High efficiency: It drills much faster than traditional percussion methods.
- Strong versatility: It handles clay, sand, weathered rock, and more.
- Accurate verticality: The mast guide helps ensure straight holes.
- Low noise and vibration: This suits urban construction sites very well.
- Cleaner site: The auger removes soil neatly, so you spend less time on cleanup.
- Safer operation: Modern rigs come with stability controls and protective cabins.
In short, a rotary drilling rig saves time, labor, and money on nearly any piling job.
Application Fields
You can use this machinery across a wide range of projects:
- High-rise building foundations
- Bridge and flyover piers
- Highway and railway piles
- Industrial plant columns
- Solar panel support piles
- Retaining walls and diaphragm walls
- Power transmission tower bases
Each of these applications benefits from the speed and precision of rotary drilling rigs.

Rotary Drilling Equipment FAQ
13 meters. Our standard YG rotary drilling rig reaches a maximum depth of 13 meters. This depth suits most foundation piles for buildings and bridges. We can also customize deeper rigs upon request. The actual depth may vary slightly depending on soil type and the tooling you use.
Focus on three key factors: required drilling diameter, target depth, and soil conditions. Our rig handles diameters from 600 mm to 1600 mm. If your project needs larger piles, we can recommend specific modifications. Also, check site access. The compact design of our machine works well in confined areas.
It handles soft to medium rock with standard augers. For hard rock layers, you need a core barrel or rock auger. The standard flight auger performs best in clay, sand, and gravel. Tell us about your ground conditions. We will suggest the most effective drilling tools for your job.
Daily checks should include engine oil, hydraulic fluid, and hose conditions. Change hydraulic filters at regular intervals. Grease the Kelly bar and rotary drive weekly. Our user manual provides a full maintenance schedule. Following these simple steps keeps your rotary drilling equipment reliable and extends its service life.
Yes, absolutely. Every rig we sell includes a one-year warranty on major components. The warranty covers manufacturing defects. Our support team assists you with video diagnostics and spare parts delivery. You can buy with full confidence in our after-sales care.
