Precautions for the operation of hydraulic breaker hammers for excavators？

Hydraulic breaker hammers are extensively used in various applications like mining, railway and highway repair, building demolition, and reinforced concrete crushing. Operating these hammers effectively requires careful attention to the operational manual to prevent damage to both the equipment and the excavator. To operate a hydraulic breaker hammer correctly, operators must adhere to the following key considerations:

1. Choose the Correct Striking Direction:

   • Ensure that the striking direction of the breaker hammer aligns in a straight line with the steel fiber during operation. Any tilt in the striking direction can lead to slippage of the steel fiber, risking breakage or jamming of the fiber and piston, and increasing wear on the lower sleeve.

2. Apply Appropriate Striking Force:

   • Select a suitable striking force to effectively crush materials. Insufficient force can hinder efficient crushing, potentially transmitting reaction forces to the breaker hammer body and the excavator loader arm, causing damage. Excessive force can result in sudden tilting during operation, risking damage to the breaker hammer and introducing harmful vibrations to the excavator loader's movement components.

3. Precautions During Hammer Operation:

   • Install a protective net to prevent shattered debris from damaging the excavator loader's glass and injuring operators.
   • Cease operation if there is violent hose vibration, as it may indicate a fault. Promptly inspect intense hose vibrations to prevent damage to the hammer parts. Avoid empty strikes after breaking an object, as continuous empty strikes can loosen or break hammer bolts, potentially adversely affecting the excavator loader.

4. Flexible and Correct Hammer Operation:

   • When dealing with hard and large stones, consider breaking their edges first to protect the hammer body.
   • Operate the hammer at a suitable engine speed to ensure optimal performance.
   • Avoid direct falling of the hammer onto stones for breaking, as this can subject the hammer and the excavator loader to excessive force, leading to potential component damage.

By meticulously observing these precautions, operators can guarantee the safe and efficient operation of hydraulic breaker hammers with excavators, optimizing performance and reducing risks of equipment damage.
