A pile breaker mounts on an excavator and cuts through concrete piles with hydraulic force. Instead of using jackhammers or hand tools, a single operator positions the machine around a pile, closes the jaws, and fractures the concrete cleanly. The rebar stays intact. No damage to the reinforcement. No flying debris. Without this attachment, crews spend hours chipping away at pile heads with handheld breakers. That work is loud, dusty, and hard on workers’ bodies. With this tool, the same job takes minutes. For foundation contractors, bridge builders, and marine construction crews, it cuts labour time by 80%.

YG Machinery builds each module from high-strength steel. The hydraulic cylinders come with chrome-plated rods. Every unit test runs before shipping.
Beyond pile breakers, YG Machinery manufactures several other excavator attachments and construction equipment:
- Hydraulic breakers (from 200kg to 4000kg for 1-50 ton excavators)
- Hydraulic magnets (for scrap and demolition material handling)
- Mechanical grabs (for sorting and demolition work)
- Rotating pulverisers (for concrete crushing and rebar separation)
- Auger drives (for foundation drilling and pile pre-drilling)
- Compaction wheels (for trench backfill and landfill work)
- Quick couplers (pin grabber and hydraulic types for fast tool changes)

How This Pile Crusher Works
A pile crusher uses modular jaws that close around the concrete pile. Each module contains a hydraulic cylinder. When you send oil flow from your excavator, all cylinders extend at the same time. The jaws push inward, cracking the concrete along multiple lines at once.
Here is the process. Position the excavator so the pile breaker sits level around the pile head. Close the jaws. The concrete fractures in a ring pattern. Open the jaws. Rotate the machine 90 degrees. Close again. The concrete breaks into small pieces that fall away.
The rebar stays completely undamaged. The machine cracks only the concrete, not the steel. This matters because damaged rebar means a failed foundation inspection. With this method, the rebar stands clean and straight, ready for the next construction step.
YG Machinery designs the cylinder timing so all jaws apply equal force. No single wedge pushes harder than the others. Even pressure means even cracking. No jamming. No broken machine parts.
Choosing the Right Pile Head Breaking Machine for Your Job
A pile head breaking machine comes in different sizes. Choosing the right one starts with measuring your pile diameter. The table above shows the range for each module count.
For piles under 600mm, the 4-module unit works fine. It weighs 1600kg and fits most 20-ton excavators. The small size also means you can work in tight areas like foundation corners or alongside existing walls.
For piles between 800mm and 1500mm, you need 9 to 12 modules. These units weigh 3 to 4 tons. A 25-ton excavator handles them easily. Most bridge and building foundation piles fall into this range.
For piles over 1500mm up to 2500mm, you need 13 to 18 modules. These units weigh up to 6 tons. A 35-ton or larger excavator is necessary. Some very large piles may require a separate hydraulic pump station instead of using the excavator’s auxiliary circuit. YG Machinery can advise on this.
The single module weight is 335kg. Each module adds that much weight and increases the pile diameter range by about 50-150mm. You can start with fewer modules and add more later if your job changes.
5 Conditions Your Excavator Must Meet
What an Excavator Pile Breaker Includes
It comes as a modular kit. You get the number of modules you order, plus connecting pins, hydraulic hoses, and a manifold block. The manifold splits your excavator’s oil flow evenly to all cylinders.
Assembly happens on site. You pin the modules together in a ring around the pile. The location pins (Φ35mm) align everything. No special tools needed. Two workers can assemble a 12-module unit in about an hour.
The hydraulic system connects to your excavator’s auxiliary circuit. One hose supplies pressure. The other returns oil to the tank. A manual valve in the cab controls the jaws – open or close. No complex electronics. No sensors to break.
YG Machinery also supplies a set of spare wear plates. These bolt onto the inside of each jaw. When they wear down from concrete contact, you replace just the plates. The main module casting lasts for years.
Excavator Pile Breaker: Key Design Features That Matter
Several design features make this equipment reliable on tough job sites.
The hydraulic cylinders mount inside the module frame. Concrete dust and debris cannot hit the cylinder rods directly. This keeps the seals alive longer. Cheap pile breakers have exposed cylinders. Those get damaged within weeks on dusty jobs.
The jaws have replaceable carbide teeth. These teeth bite into the concrete and create stress points. The cracks start at the teeth and spread through the pile. Dull teeth slow down the work. Replace them in minutes with a hex wrench.
The module frames use high-strength cast steel. A single piece of steel forms the main structure. No welded joints to crack under pressure. The pins connecting modules are induction-hardened. They resist wear even after thousands of cycles.
The manifold block includes pressure relief valves. If a cylinder binds on a piece of rebar or hard aggregate, the relief valve opens. The other cylinders keep moving. No single stuck cylinder stops the whole machine.
Applications Across Construction Projects
This equipment works wherever concrete piles need trimming to grade. Here are the most common uses.
Bridge foundations. Bridge piers sit on groups of concrete piles. After driving or pouring the piles, crews must cut them to the same elevation. A pile breaker does all the piles on a bridge footing in one shift. Hand methods take three days.
Building foundations. High-rise buildings transfer loads through piles to bedrock. Each pile needs a clean, flat head for the pile cap. The machine leaves a surface ready for concrete placement. No additional chipping or cleaning needed.
Marine structures. Docks, piers, and jetties use piles driven into the seabed. Working over water makes hand methods dangerous. An excavator on a barge uses a pile breaker safely above the waterline. The broken concrete falls into the water – no problem.
Wind turbine foundations. Each wind turbine sits on a ring of 20 to 40 piles. Each pile needs precise height trimming. A pile breaker moves from pile to pile quickly. The turbine foundation goes in days faster.
Seismic retrofits. Older buildings get new pile foundations during earthquake upgrades. The new piles must tie into existing structures. Precise pile height control matters. The machine delivers that precision.
FAQs About Pile Head Breaking Machine
Yes. The machine cracks only the concrete. The rebar stays intact. Even piles with dense rebar cages work fine. The jaws push concrete away from the steel. You may need an extra rotation if the rebar is very tight.
A typical 600mm diameter pile takes 30 to 60 seconds. A 1500mm pile takes 2 to 3 minutes. Hand methods take 20 to 40 minutes per pile. The time savings add up fast on large jobs.
Any excavator with an auxiliary hydraulic circuit works. The machine needs 20 litres per minute. Most 20-ton and larger excavators meet this. For very large pile breakers (17-18 modules), YG recommends a separate hydraulic pump station.
No. The hydraulic cylinders and pins are not sealed for submersion. For underwater pile cutting, you need a specialised unit with marine seals. YG offers this as a custom order.
Measure your pile diameter at the cut point. Piles often flare near the top. Use the widest measurement. Match that to the Pile Diameter Range column in the table. Order the number of modules shown. For piles between sizes, order the larger unit.
Each module has its own cylinder. If one fails, the other modules still work. You can finish the pile or the shift. Then replace the failed module. YG stocks individual modules for quick swap-out. Keep one spare module on large jobs.
