Hydraulic Breaker Attachment

A hydraulic breaker attachment is mounted on an excavator. It primarily utilises a hydraulic system to drive a piston in high-speed reciprocating motion, using its powerful impact force to break rocks, concrete, asphalt, and building structures. Hydraulic breakers are characterised by their strong impact force, high construction efficiency, and wide adaptability to various working conditions, making them widely used in mining, road construction, building demolition, municipal engineering, and tunnel engineering, among other industries. With the continuous development of the modern construction machinery industry, hydraulic breakers have become one of the most common and important attachments for excavators. Whether in large-scale mining projects or urban demolition projects, many construction companies prioritise equipping their operations with hydraulic breakers to improve construction efficiency and profitability.

7 Core Features of Hydraulic Breaker Attachment

1. Strong Impact Power & High Efficiency: Driven by the excavator’s hydraulic system, this rock hammer excavator delivers a stable and powerful striking force. It crushes hard rock and reinforced concrete quickly, greatly improving working efficiency compared with manual tools and traditional breaking equipment. It shortens project cycles effectively.
2. Easy Installation & Good Compatibility: The hydraulic breaker attachment features a standard connecting structure. It can be mounted on different types of excavators in a short time, including mini, medium and large excavators. Operators can switch between the breaker and the digging bucket freely to realise multi-purpose use of one machine.
3. Durable Structure & Long Service Life: Key components adopt high-strength wear-resistant alloy materials. The internal structure is optimised for shock resistance and fatigue resistance. Even under long-time continuous heavy-load operation, the excavator breaker hammer maintains stable performance and reduces frequent part replacement.
4. Precise Operation & Low Vibration: It achieves accurate breaking with a controllable impact range. It will not cause excessive damage to surrounding buildings or road foundations. The built-in buffer structure lowers vibration and noise, making it suitable for operation in densely populated urban areas.
5. Nitrogen-assisted Energy Saving Design: Equipped with a nitrogen gas boosting system, the breaker enhances impact force while reducing hydraulic consumption. It lowers the fuel cost of the main excavator and brings better economic benefits for long-term use.
6. Wide Environmental Adaptability: This mini excavator rock breaker and heavy-duty models can work normally in high temperature, low temperature, dusty and muddy construction sites. The sealed body prevents dust and sediment from entering internal parts, adapting to complex outdoor working conditions.
7. Reasonable Price & Low Maintenance Cost: We offer a favourable excavator breaker price for different models. The whole machine has few vulnerable parts, and daily maintenance is simple. Users only need to do regular lubrication and inspection, which cuts later operating expenses greatly.

7 Main Applications about Hydraulic Breaker Attachment

1. Building Demolition Works: It is the first choice for dismantling old buildings, concrete walls, floors and abandoned foundations. The breaker hammer for excavator completes demolition safely and efficiently without using dangerous blasting.
2. Road Construction & Renovation: Used for breaking old asphalt pavement, concrete road surface, roadbed rock and road expansion reconstruction. It supports road repairing, resurfacing and trench excavation along roads.
3. Mining & Quarrying: In mines and quarries, it crushes large rocks after blasting and splits oversized stones. The rock hammer excavator realizes secondary rock breaking and facilitates loading and transportation.

The customer needed cost-effective mini excavator rock breaker with matched pressure and flow, and competitive excavator breaker price.
• Solution: We recommended YG600 hydraulic breaker attachment (60mm chisel, 2–5 ton carrier, 90–120kg/cm² pressure, 25–50L/min flow, 600–1100bpm frequency). Compact 140kg body fits mini excavators perfectly for narrow urban operation.
• Effect: Stable hydraulic output ensures precise breaking without damaging surrounding roads and buildings. Standard parameters match mini excavator load, zero overload failure. Construction efficiency improved by 35%, fully meeting Italy’s urban noise and safety regulations.
• Customer Feedback: “This mini excavator rock breaker runs steadily with precise striking. The excavator breaker price is very competitive, ideal for our municipal narrow-space demolition jobs.”

Case 2: Repeat Order – India (Quarry & Hard Rock Mining Enterprise)

• Customer Background & Identity: A large Indian quarry operator, mainly engaged in hard rock mining and stone crushing, using 30–40 ton large excavators for long-term high-intensity rock breaking work all year round.
• Difficulties: Hard rock requires high pressure and strong impact. Previous breakers had insufficient working pressure, low blow frequency and severe wear, causing frequent shutdown maintenance and high replacement costs. The client needed durable, heavy-duty rock hammer excavator.
• Solution: The customer placed a repeat order for YG1650 excavator breaker hammer (165mm chisel, 30–40 ton carrier, 180–200kg/cm² high pressure, 200–260L/min flow). High impact force adapts to local hard rock mining conditions.
• Effect: Super-high working pressure efficiently crushes large hard rocks. Stable 250–400bpm blow frequency ensures continuous high-output operation. Failure rate greatly reduced, maintenance downtime saved, and overall mining productivity improved significantly.
• Customer Feedback: “We repurchased YG1650 breaker hammer for excavator. It withstands harsh mining conditions, powerful and durable, bringing great profit for our quarry business.”
