The Hydraulic Silence Breaker SK81S is a high-performance, low-noise hydraulic breaking tool designed for efficient and quiet operation in various construction and demolition scenarios. Engineered with advanced noise reduction technology and robust structural design, it combines powerful breaking force with minimal environmental impact, making it an ideal choice for projects requiring low noise emission, such as urban construction, indoor renovation, and areas near residential or sensitive facilities.
1. Product Overview
The SK81S hydraulic silence breaker is a medium-sized breaking tool that integrates hydraulic transmission, noise reduction, and wear resistance. It is compatible with most medium-sized excavators (18-25 tons) and can be quickly installed and disassembled, ensuring high work efficiency and strong adaptability. Its core advantage lies in the integrated silence design, which effectively reduces operating noise to below 85dB, far lower than the industry average, while maintaining excellent breaking performance.
2. Core Features & Advantages
-
Superior Silence Performance: Equipped with a double-layer sound insulation casing and damping buffer structure, the SK81S minimizes noise generated by hydraulic impact and mechanical vibration. The noise level during operation is controlled at 78-85dB, avoiding noise pollution and meeting strict environmental protection standards in urban and residential areas.
-
Powerful Breaking Force: Adopting a high-pressure hydraulic system with a maximum working pressure of 160 bar and a striking frequency of 1800-2200 bpm, the SK81S delivers strong and stable breaking force, capable of efficiently crushing concrete, rock, asphalt, and other hard materials. It ensures fast construction progress and reduces work cycles.
-
Durable & Wear-Resistant: The striking piston and tool bit are made of high-strength alloy steel,经过 special heat treatment to enhance hardness and wear resistance. The integrated hydraulic seal design prevents oil leakage and extends the service life of the equipment, reducing maintenance costs.
-
Energy-Saving & Efficient: The optimized hydraulic circuit design reduces energy loss, making full use of the excavator’s power output. It features automatic frequency adjustment according to the load, ensuring stable operation and reducing fuel consumption. The quick coupling design allows for fast connection and disconnection, improving work efficiency.
-
Easy Operation & Maintenance: The SK81S adopts a user-friendly design, with simple operation that can be mastered quickly by operators. The detachable structure facilitates daily inspection, maintenance, and replacement of wearing parts, reducing downtime and ensuring continuous operation.
