Why Choose Beilite Silenced Type Hydraulic Breakers?

Sound Isolation (Noise and Vibration Reduction)

Beilite silenced type hydraulic breakers combine advanced vibration damping systems and a sound isolation body to significantly reduce noise and vibration without compromising impact energy. A fully enclosed body structure designed with special insulation materials isolates operating noise, while internal damping technology minimizes the transmission of vibration to the host machine. These systems increase operator comfort, reduce fatigue and ensure full compliance with strict noise regulations. The result is quieter, smoother and more efficient performance in urban, residential and sensitive working environments.

ABF Usage and Considerations

To deactivate or activate the Anti-Blank Hit Prevention (ABF) function on your Beilite breaker, follow these technical steps in sequence: ① place the crusher on a level and solid ground; ② relieve residual pressure in the hydraulic system to ensure safety; ③ close the shut-off valve; ④ remove the plug of the ABF valve; ⑤ carefully remove the ABF valve; ⑥ check the valve orientation; note that the threaded end must face outwards to activate the ABF function and inwards to deactivate it; ⑦ install the ABF valve according to your operational requirements; ⑧ check the plug and O-ring for damage and replace if necessary, then reinstall and tighten the plug; ⑨ finally, note that the ABF function is disabled by default at the factory.

Dust Resistant Design

Beilite silenced type hydraulic breakers feature a special dust resistant tip and bushing system. Designed with angled edges to deflect debris and dust away from the cylinder, this structure is optimized for heavily dusty environments. This enhanced protection ensures that the impact force remains stable and significantly extends the service life of the breaker, even in the harshest operating conditions.

How to Choose Beilite Hydraulic Breaker Automatic Lubrication Pump Options?

Mechanical Automatic Lubrication Grease Pump

The Mechanical Automatic Lubrication Grease Pump adjusts the greasing process to the operating conditions and has a refillable cartridge that reduces costs. It automatically discharges grease by sensing the vibration of the crusher. The system consists of pump, protection cover, imbus bolt (with hexagon socket) and grease tube to ensure efficient lubrication.

Hydraulic Automatic Lubrication Grease Pump

The Hydraulic Automatic Lubrication Grease Pump features a disposable cartridge for easy replacement and manual grease adjustment. It senses hydraulic pressure changes and discharges grease with every stroke of the breaker. The system consists of pump, protection cover, imbus bolt and grease pipe to ensure efficient lubrication.

Electric Automatic Lubrication Grease Pump

Electric Automatic Lubrication Grease Pump offers precise and timely lubrication with electric control valve. The large grease tank provides hundreds of hours of use with each refill. Connected to the excavator with grease pipes, this pump is suitable for various working conditions.
