YG Machinery

An excavator pile driver, as the name suggests, is a pile-driving device mounted on an excavator. It converts the excavator’s hydraulic power into the impact or vibration force required for pile driving, enabling the pile to sink quickly into the ground. This device is also known as an “excavator hydraulic pile hammer,” “excavator vibratory hammer,” or “excavator pile arm.” Its core function is to utilize the excavator’s mobility and hydraulic system to drive various types of piles (such as sheet piles, H-beams, cement piles, and wooden piles) into the ground to form a stable pile foundation.

YG’s excavator pile driver is typically used as an attachment for excavators, mounted on the front end of the excavator’s boom and arm via a quick-connect coupling. Its main components include: a vibratory housing (or impact hammer), a clamp (for holding the pile), a hydraulic motor (or hydraulic cylinder), a shock absorption system, and a connecting frame. We use high-strength alloy steel and precision machining processes to ensure the equipment is robust and durable. The eccentric wheel inside the vibratory housing rotates at high speed, driven by the hydraulic motor, generating a powerful vertical vibration force that allows the pile to overcome soil resistance and sink rapidly. The clamp design is flexible and can accommodate piles of different shapes and sizes. YG, a professional manufacturer of excavator pile drivers, has deep expertise in the engineering equipment field. We not only provide standard excavator pile drivers but also supply supporting equipment such as pile breakers and excavator drum cutters, offering a one-stop solution for piling and related construction challenges in small and medium-sized projects. This helps companies reduce costs, increase efficiency, and improve construction quality. Contact us now for more product information.

Working Principle of YG Mini Excavator Pile Driver Attachment

1. Equipment Connection: Secure the excavator pile driver to the excavator using the adapter bracket, ensuring a firm connection. Adjust the hydraulic lines and electrical control system to enable coordinated operation between the piling equipment and the excavator. The excavator-mounted pile driver features a quick-attach design for easier connection.
2. Pile Positioning: The operator places the pile at the preset construction position. Using the intelligent positioning system in the excavator cab, adjust the angle and height of the piling equipment to ensure the pile is vertical and accurately positioned, with a deviation controlled within ±5cm to prevent pile tilting.
3. Hydraulic Piling: Start the excavator. The hydraulic system powers the pile hammer, driving it up and down at a frequency of 15-30 times per minute, driving the pile to the preset depth (1-8 meters). The driving force can be adjusted flexibly according to the pile type and soil conditions.
4. Work Reset: After the pile reaches the preset depth, stop pile driving, adjust the pile hammer to reset, move the excavator, transfer the equipment to the next pile driving position, and repeat the above steps; if pile trimming is required, a pile breaker can be used for subsequent operations, and an excavator drum cutter can be used to cut the pile.

Features and Advantages of YG Excavator Pile Driver Attachment

1. High-efficiency piling, improving construction efficiency: Utilizing a high-power hydraulic pile hammer (15-45kW), the piling frequency is 15-30 times/minute, with a single impact force of 10-50kN and a piling depth of 1-8 meters. This is 15-20 times faster than traditional manual piling, enabling the completion of 80-120 piles per day, significantly shortening the construction cycle and meeting the batch piling needs of small to medium-sized projects.
2. Flexible adaptation, multi-purpose: Compatible with various excavators ranging from 10-30 tons, with convenient connection and no excavator modification required. It can also be equipped with a mini excavator pile driver attachment to suit smaller excavators, meeting the piling needs of small projects and confined spaces. Furthermore, it is compatible with a pile breaker, enabling integrated piling and pile breaking operations, improving equipment utilization.
3. Precise Positioning, High Construction Quality: Equipped with an intelligent positioning system, the positioning accuracy is ≤±5cm, accurately controlling the verticality of the pile (deviation ≤0.5°), preventing pile tilting, ensuring stable foundation support, reducing rework caused by positioning deviations, and resulting in construction quality superior to similar products. It can also be used with an excavator drum cutter to achieve simultaneous pile cutting and piling operations.
4. Intelligent Control, Convenient Operation: Utilizing a PLC intelligent electronic control system integrated into the excavator cab, it features one-button start/stop, and flexible adjustment of piling force and frequency. Ordinary excavator operators can operate it after 2 days of training, eliminating the need for a professional piling team, reducing labor and training costs.
5. Stable and Durable, Low Failure Rate: Key components are made of highly wear-resistant and high-strength materials, resulting in an overall equipment failure rate of less than 1.5%. It can operate continuously for 24 hours, adapting to complex outdoor construction environments, and its maintenance costs are far lower than those of similar products. The hydraulic system uses imported seals, resulting in low leakage and stable operation, reducing downtime for maintenance.
6. Safe and Reliable with Comprehensive Protection: Equipped with overload protection, hydraulic buffer, and emergency stop devices, it effectively prevents equipment overload, pile breakage, and other emergencies, ensuring the safety of operators and equipment. There is no significant noise or dust pollution during pile driving, meeting environmental protection standards for engineering construction.
7. Lightweight Design and Convenient Transportation: Weighing only 2-8 tons, the equipment is compact and can be transported by ordinary trucks without the need for specialized transport equipment, resulting in low transportation costs. It adapts to the relocation needs of different construction sites, making it particularly suitable for the frequent relocation characteristics of small and medium-sized projects.
