The hydraulic pile crusher is hydraulically driven. Typically, a pile breaker needs to connect with an excavator. Alternatively, the power of a hydraulic station is to provide pressure to multiple cylinders of the pile cutter. This equipment is a good helper for removing or breaking concrete pile foundations. Pile breakers are key when people need to remove or remodel existing piles.YG can offer you 4 types of pile breakers, round pile breakers, square pile breakers, modular pile breakers, and stationary pile breakers.

Hydraulic Pile Crusher Application
Hydraulic pile crusher is widely used in various civil engineering projects, such as pile foundation works, large buildings, roads, bridge alteration and demolition works, submerged pile works, underground equipment repair, and renovation, water conservancy works, municipal works, etc. Pile breakers can process different pile foundation forms such as grouted piles, prefabricated piles, etc. It can be divided into circular pile breakers, square pile breakers, and wall breakers from the shape of pile heads. The round pile cutter is suitable for pile diameters from 250mm to 2500mm, and the square pile cutter is suitable for pile side lengths from 250-650mm, so it can meet the requirements of all kinds of large-scale foundation construction.
Hydraulic Pile Breaker Project Cases
Highway Pier Project in Romania
The site required breaking cast-in-place piles with a diameter of 1300-1500mm. The client used a 35-ton hydraulic excavator as the power source. Referring to our module matching table, we recommended a 12-module combination with a total weight of 3960kg, suitable for pile diameters of 1300-1500mm. This unit delivers a maximum thrust of 300KN. Each module is fitted with crushing teeth of 110mm diameter. The hydraulic system requires a minimum flow rate of 20L/min and a working pressure up to 300MPa. The device is driven directly by the excavator’s original hydraulic lines. Position pins (Φ35) are installed to keep all modules well aligned. On-site, the 12 modules are arranged in a circle. Hydraulic cylinders drive all crushing teeth to squeeze the pile head inward simultaneously. It only takes 3 to 5 minutes to break one large-diameter pile. The working efficiency is much higher than that of manual jackhammers, and the broken pile surface is flat with no secondary trimming needed.
Wharf Expansion Project in Indonesia
This project involved a large number of medium-sized foundation piles with diameters of 600-800mm. Only a 25-ton excavator was available on site. Besides, the ground turned soft in rainy seasons, so the overall equipment weight was strictly limited. We selected a 4-module combination with a total weight of 1600kg. It is originally designed for 400-600mm piles, and can be adjusted to work for piles up to 800mm. Each module weighs just 335kg with dimensions of 1015×865×340mm, easy for manual moving and quick assembly. The client’s excavator only provides a maximum hydraulic flow of 15L/min, lower than the standard 20L/min. For this reason, we supplied an independent hydraulic power unit that meets 20L/min flow and 300MPa pressure. It is connected to the hydraulic pile breaker via long hoses. The equipment runs free from the excavator’s hydraulic limits, while the excavator is only used for lifting and positioning. This solution works perfectly on Indonesia’s soft ground. The 4-module set weighs merely 1.6 tons for easy lifting. A max lifting height limit (≤500mm) is equipped to guarantee operational safety.
Similarities & Differences Between the Two Projects
Both projects adopt a flexible modular design. Later in Romania, a small number of piles with diameters of 1650-1800mm appeared. The client simply added 2 modules to upgrade into a 14-module combination with a total weight of 4620kg, with no need to replace the whole machine. For continuous pile construction on some small 400mm piles in Indonesia, the 4-module set was temporarily reduced to 3 modules. The equipment features excellent flexibility.
Concrete Pile Crusher’s Structure
The structure of hydraulic pile crushers consists of high-pressure cylinders, connectors, steel braze, high-pressure oil pipe, guide flange, and piston rod. The high-pressure oil cylinder and steel brazier form a connecting unit through the connector. These several connecting units make up the whole machine.
Hydraulic Pile Breakers Working Principle
The pile breaker provides pressure to multiple cylinders of the pile interceptor through a power source. Then the cylinders directly drive the brazing rod and squeeze the pile body at the same time to make the pile head amputated. The hydraulic pile crusher adopts a highly modularized combination of modules connected by pins. Therefore, it can be combined with a different number of modules to remove the pile head of a certain range of diameters. The pile cutter is easy to operate, has high efficiency, and has low noise during construction, which is suitable for pile group construction projects.
Pile Crusher’s Working Process
- Positioning the pile: Usually, the hydraulic control system is to fix the clamping jaws of the pile beaker on the pile.
- Applying force: The pile driver applies force to the pile via a hydraulic system. This force can be generated by the excavator and the hydraulic cylinder unit.
- Separating the pile: The force applied by the pile driver separates the pile from the ground, usually by breaking the connection between the pile and the ground or the structure of the pile itself.
- Removing the pile: After the hydraulic pile crusher separates the pile, the pile breaker typically uses a gripping jaw to grasp the pile and then removes it to the target location.
Operation Procedure of Concrete Pile Breaker
- We need the line to determine the location and number of piles and clear the surrounding obstacles.
- Then the operator will move the excavator to the location of the concrete pile.
- The operator needs to use the bucket of the excavator to remove the soil or surrounding material.
- then securely attach the pile breaker to the boom of the excavator.
- Align the breaking part of the pile driver with the pile and start operation.
- Keep operating the pile driver until the piles are broken.
- After breaking the piles, use the bucket of the excavator to remove the remaining piles and materials.
Features of the Hydraulic Pile Cutter
- Hydraulically driven pile breaker with high efficiency and low noise.
- The hydraulic pile crusher is modular and can cut off pile heads of different diameters by combining different numbers of modules.
- The pile-breaking operation is simple, no need to train workers, and the operation is quite stable and reliable.
- The pile breaker can be connected with many kinds of engineering machinery. For example, it can be hooked to excavators, cranes, telescopic booms, and other construction machinery.
- YG adopts high-quality material to manufacture the pile breaker, which has a long service life.
