This mining rock breaker SB81 with auto grease lubrication system is powerful and excellent excavator jack hammer. Equipped with 140mm chisel, the SB81 hydraulic hammer is widely used as quarry hydraulic hammer and concrete machinery. As a rock stone breaking machine, this hydraulic breaker hammer for 19-26 ton excavator is essential construction machinery attachment.
1. The automatic lubrication system regularly and quantitatively injects lubricant into friction areas, reducing friction and minimizing component wear.
2. Automatically supplies lubricant at a preset frequency and volume.
3. Requires no manual intervention and automatically completes lubrication operations during equipment operation.
The box type silent hydraulic breaker features a monolithic, box-shaped housing and is top-mounted, making it suitable for top-mounting on excavators for crushing operations. Its long overall length allows for a long crushing distance. The fully enclosed housing incorporates internal noise reduction features, such as MIC shock absorption technology and high-tech special materials, to effectively reduce noise transmission. It utilizes an advanced hydraulic system and is constructed from high-strength alloy materials. Its specialized design and high-quality manufacturing process ensure excellent wear and corrosion resistance, enabling long-term, stable operation in high-intensity operating environments.
