HOW TO CHOOSE A HYDRAULIC BREAKER

Selecting the appropriate hydraulic breaker for work machinery is a significant concern in the construction and mining sectors. Using an incompatible attachment can cause damage to both the machinery and the breaker, leading to substantial financial loss. To ensure you make the right choice, it’s essential to consider all your options carefully.

Here’s a list of critical features to consider when purchasing a hydraulic breaker:

  1. WEIGHT OF THE BASE MACHINE

The hydraulic breaker’s weight should not exceed 10% of the base machine’s weight.

For construction machinery up to 10 tons, choose a breaker that is 8-10% of the base machine’s weight. For machinery over 20 tons, select a breaker that is 7-10% of the machine’s weight. Lighter breakers are used for machinery where the breaker weight is up to 5% of the base machine.

No strict industry standards exist, as the choice depends on the type of work. For stationary tasks in a quarry or mine, use heavy breakers (7-10% of the base machine’s weight). For tasks like building demolitions, use lighter breakers (up to 5% of the base machine’s weight).

  1. OIL FLOW

The hydraulic breaker’s oil flow should match the base machine’s pump productivity.

Each breaker requires a specific flow and pressure from the hydraulic pumps, determined by the breaker manufacturer. Therefore, the hydraulic pumps’ capacity on the base machine determines the breaker selection to ensure full capacity use.

  1. WORKING PRESSURE

An operating valve for the hydraulic line is necessary to control pressure for optimal equipment operation.

Setting a safe working pressure level is crucial for smooth breaker operation. An operating valve limits the safe working pressure to a specific level, preventing high pressure from damaging hydraulic system components.

  1. PRODUCTIVITY

Breakers with higher power and work per hour are considered more productive.

Productivity is measured by impact energy multiplied by impact frequency. These indicators can be challenging to identify in real work, and manufacturers often exaggerate data. Choose breakers with a switch to select the operating mode, allowing you to adjust power and speed for increased productivity based on field requirements.

  1. CONSTRUCTION

Fewer parts, seals, and connecting threads mean a more reliable hydraulic breaker.

Breakers with simpler designs and fewer components require less maintenance and are easier to service, leading to better performance.

  1. SIMPLICITY OF OPERATION AND SERVICING

Easier access to lubrication points, hose couplings, and tool changes makes a breaker more user-friendly.

For simplicity, opt for models with automatic tool lubrication. The usability of the breaker depends on the ability to replace the bushing, accumulator membrane, and hydraulic valve without completely dismantling the breaker.

  1. EXTERNAL NOISE AND VIBRATION

Sound and vibration levels are crucial when working in urban areas requiring minimal noise.

The breaker’s sound is reduced if its impact mechanism is enclosed and if polyurethane buffers are placed between the impact mechanism and the body frame, preventing vibrations from reaching the hammer body. A silencer reduces wear on the bushing and pins by protecting the arm connection from vibrations.
