Compact SB20 Side Type Hydraulic Breaker is specifically designed for 1.5 to 2.5-ton mini excavators (such as Kubota U17, CAT 301.8, Yanmar ViO25). The side-mount design offers a lower overall height, providing superior stability for mini excavators during demolition and landscaping projects. Engineered with a 45mm diameter chisel, it delivers high-frequency impact while protecting the carrier’s lightweight boom.
- Optimized for Mini Excavators: Weighing only 130kg, the SB20 maintains the balance of small carriers, preventing tipping during lateral breaking.
- 20CrMo Internal Power Cell: Despite its small size, the SB20 features a high-tensile 20CrMo alloy steel cylinder with vacuum heat treatment, ensuring the same durability as our 20-ton heavy-duty models.
- Urban-Friendly Operation: The side-type structure allows for better visibility and precise control in narrow spaces, making it ideal for indoor renovations and residential landscaping.
