Key Features & Advantages
1. Superior Top Type Design: The top-type structure offers a longer total length and optimized center of gravity. This design makes it significantly more convenient for vertical excavation and demolition work, while the balanced weight distribution reduces the risk of chisel breakage.
2. High-Efficiency Accumulator System: Equipped with a high-performance accumulator, the SM135 effectively compensates for pressure fluctuations in the hydraulic circuit. This prevents pulsation, protects the carrier's hydraulic pump, and ensures consistent striking force.
3. Premium Alloy Steel Chisel: Our chisels are manufactured from select alloy steel raw materials. Through high-precision deep heat treatment, the tool achieves exceptional heat and wear resistance, allowing for continuous operation in the harshest environments.
4. Durable Main Valve & Piston: The precision-machined piston and cylinder reduce internal resistance and improve efficiency. A specialized damping system reduces recoil force, protecting the excavator boom while increasing the overall blow force.
5. Energy-Saving Nitrogen Chamber: The compact Nitrogen chamber design ensures stable pressure and high-impact energy output. This optimized system reduces energy consumption without compromising the hammer’s destructive power.
6. Robust Box Shell Structure: The durable welding structure provides perfect protection for the cylinder and bushings. Full sealing measures prevent dust from entering the system, significantly extending the service life of the internal components.
Mining: Primary and secondary breaking in quarries and open-pit mines.
Metallurgy: Slag clearing and demolition of furnace foundations.
Road Construction: Road repairing, pavement breaking, and foundation work.
Railway & Tunneling: Tunnel excavation and bridge demolition.
Construction: Demolition of reinforced concrete buildings and structures.
Ship Repair: Clearing clam and rust from ship hulls.

Q1: Why does my hydraulic breaker leak oil only in winter?
In cold weather, temperature differences between the breaker housing and internal components can cause temporary thermal contraction. Newly installed oil seals may develop small clearances under these conditions, leading to minor oil seepage. This is usually temporary and improves after proper warm-up.
Q2: Is oil leakage after replacing a new seal a quality problem?
Not necessarily. New seals made of NBR rubber require proper operating temperature to achieve full elasticity and sealing performance. Minor leakage during cold conditions does not indicate a manufacturing defect in most cases.
Q3: Should hydraulic breakers be preheated like excavators?
Yes. Hydraulic breakers rely on hydraulic oil pressure and dynamic sealing. Without preheating, cold oil and rigid seals can increase wear, reduce sealing efficiency, and shorten service life.
Q4: How long should I preheat a hydraulic breaker in winter?
There is no fixed time. Preheating should continue until hydraulic oil temperature rises and the breaker operates smoothly without abnormal noise or vibration. Light, controlled impacts are recommended during this stage.
Q5: Can improper preheating damage the chisel or breaker?
Yes. Operating a breaker under full load with cold oil can cause excessive stress on the chisel, piston, and seals, leading to premature wear, cracks, or internal damage.
Q6: Does this issue apply to all hydraulic breaker brands?
Yes. Thermal contraction and sealing principles are universal. This phenomenon can occur across all hydraulic breaker brands when operating in cold climates without proper warm-up procedures.
