SB50 Side Type Hydraulic Breaker Triangular Hammer for 10-12t Excavator, Heavy Duty

Parameters / Specifications

All values are nominal. Custom configurations available for specific carrier models and working conditions.

Product Technology

The SB50 is manufactured using advanced CNC machining and precision heat treatment. The cylinder bore is diamond-honed to a mirror finish, reducing internal leakage and friction. The piston is forged from high-grade alloy steel and induction hardened to HRC 58–62, providing exceptional wear resistance and fatigue strength. The accumulator diaphragm is made from high-temperature resistant elastomer, tested for millions of cycles. All critical seals are sourced from premium brands to guarantee leak-free operation.

Product Working Principle

The SB50 operates on a nitrogen-fired (gas-assisted) principle. Hydraulic oil from the excavator’s auxiliary circuit enters the breaker’s control valve and pushes the piston upward, compressing nitrogen in the rear chamber. When the valve shifts, the compressed nitrogen expands rapidly, forcing the piston downward to strike the chisel with tremendous kinetic energy. The triangular side-type housing encloses the working components, protecting them from dust and debris while allowing the operator to work close to walls and obstacles. This design delivers high-impact blows with reliable performance in confined spaces.

FAQ

Q1: Will the SB50 fit my excavator?
The SB50 side type breaker is designed for excavators weighing 8.0–15.0 tons with auxiliary hydraulic flow of 80–120 L/min and working pressure between 150–170 bar. If your machine falls within this range and uses a standard side pin-on coupler, it should be a direct fit. Contact us with your excavator make and model for a confirmed compatibility check.
Q2: What type of chisel should I use?
For penetrating hard rock and reinforced concrete, use a moil point chisel. For breaking softer, layered materials like asphalt, brick, or concrete slabs, choose a flat (blunt) chisel. Both types are available in 100mm diameter for the SB50.
Q3: How often should I grease the chisel?
Apply high-quality chisel paste every 2 hours of breaker operation, or every hour in dusty or abrasive conditions. Always press the chisel firmly against the ground while greasing to force fresh lubricant into the bushing contact area.
Q4: What nitrogen pressure should I maintain?
The correct nitrogen pre-charge for the SB50 is 15–17 bar. Check the accumulator pressure weekly using a dedicated nitrogen gauge. Low nitrogen pressure causes weak impact and slow blow frequency; high pressure can cause erratic operation and damage internal components.
Q5: Can the SB50 be used underwater?
The chisel tip may work in shallow water, but the breaker body must never be submerged. Water ingress will immediately damage seals and internal components. For continuous underwater demolition, a specialized submersible hammer is required.
Q6: What causes oil overheating when using the breaker?
Overheating typically results from operating the breaker at hydraulic flow or pressure higher than specified, a clogged filter in the excavator’s hydraulic system, or a stuck valve in the breaker circuit. Always match the excavator’s auxiliary settings to the SB50’s rated range and replace filters regularly.
Q7: How do I store the breaker when not in use?
Store the breaker upright with the chisel lightly pressed against a wooden block. Release all hydraulic pressure, cap the hoses, and apply a generous coat of grease to the chisel to prevent rust. If outdoor storage is necessary, cover with a waterproof tarp and ensure the breaker is not sitting in water.
