In traditional rock breaking and concrete demolition operations, people often rely on the ‘brute force’ of heavy hammers striking with great force. This method is not only inefficient and highly energy-intensive, but the violent recoil it generates can also cause persistent damage to the structure and hydraulic systems of the host equipment (such as excavators), shortening the service life of the entire machine. Ongoing evolution in the construction machinery sector is dedicated to transforming this ‘brute force’ into a more scientific and efficient ‘subtle power’. Among these advancements, the high-frequency vibration technology employed in modern hydraulic breakers stands as the core manifestation of this shift. Yantai Quansheng Construction Machinery Co., Ltd., based in Yantai, Shandong, is a leading enterprise deeply committed to this field, driving demolition operations into a new era of ‘using softness to overcome hardness’ through technological innovation.
I. Unveiling the Principle: How Does High-Frequency Vibration Achieve ‘Moving a Thousand Pounds with Four Ounces’?
To understand this ‘skilful force’, one must first grasp the basic working principle of a hydraulic breaker. It does not rely on simple gravitational impact, but rather utilises the hydraulic power supplied by the excavator to drive an internal piston in high-speed reciprocating motion. This converts hydraulic energy into impact mechanical energy, which is then transmitted to the chisel and applied to the object being broken.
The ingenuity of ‘high-frequency vibration’ technology lies in the significant increase in impact frequency. Traditional breakers may have a lower impact frequency, delivering a single powerful blow at long intervals—more akin to a ‘heavy punch’. In contrast, the high-frequency hydraulic breakers specialised in by Quansheng Construction Machinery achieve continuous impacts at several thousand times per minute, or even higher frequencies, through optimised hydraulic circuits and piston design.
This high-frequency, continuous impact produces two key effects:
Stress superposition effect: Although each individual impact may appear to exert little force, its energy is transmitted at high frequency, continuously accumulating at specific points within the material being broken, rapidly forming and propagating micro-cracks. When the network of cracks becomes continuous, the material will ‘neatly’ split along its weakest internal structural planes, rather than shattering indiscriminately.
Resonance and fatigue failure: For brittle materials such as concrete and rock, specific impact frequencies may approach their natural frequencies, triggering local resonance and greatly amplifying the destructive effect. At the same time, high-frequency alternating loads accelerate fatigue damage within the material, causing it to fail under stresses far below its static compressive strength.
This is precisely the scientific essence of ‘using softness to overcome hardness’: no longer attempting to ‘conquer’ the material with brute force, but rather using precise, sustained ‘skilful force’ to guide the material’s own internal structure towards failure, thereby achieving a more efficient and controllable crushing effect with less reaction force and lower energy consumption.
II. Quansheng’s Practice: Transforming ‘Skilful Force’ into Customer Value
Yantai Quansheng Engineering Machinery Co., Ltd. has a deep understanding of this principle and has integrated it into its product research, development and manufacturing. The company’s range of hydraulic breakers is the engineering embodiment of this ‘skilful force’ philosophy.
Doubled Efficiency: High-frequency impacts significantly increase the number of effective work cycles per unit of time. In mining operations, this enables faster rock fragmentation; in municipal demolition, it allows for cleaner separation of concrete from reinforcing steel. This translates to shorter project durations and a higher output-to-man-hour ratio.
Equipment-Friendly: As the force of each individual impact is optimally controlled, the peak stresses transmitted to the excavator’s boom, arm and main chassis are significantly reduced. This substantially reduces equipment vibration and noise, effectively protecting the structural components, hydraulic lines and fittings of the host excavator, thereby extending the machine’s service life and lowering overall maintenance costs.
Precision and Control: The crushing process in high-frequency mode is easier to control, producing a relatively uniform particle size. This minimises over-crushing and pulverisation, offering distinct advantages in scenarios requiring secondary crushing to specific particle sizes or the recycling of construction waste.
Wide Adaptability: Quansheng’s range of hydraulic breakers covers various tonnage requirements. Its high-frequency technology has been calibrated to adapt to a wide range of working conditions, from soft rock and frozen ground to high-strength reinforced concrete, achieving ‘multi-functionality in a single machine’.
III. Application Scenarios: Making ‘Intelligent Power’ Ubiquitous
This efficient and environmentally friendly crushing method is replacing traditional methods in multiple sectors:
Mining: Used for secondary crushing, tunnel excavation and ore separation.
Urban Construction: Used for low-noise demolition and renovation of buildings, bridges and road surfaces.
Transport Infrastructure: Used for tunnel excavation and rock slope stabilisation.
Emergency Rescue: Used to rapidly clear lifesaving access routes.
