Hydraulic Breaker SB40 Top Type Stone Breaker Hydraulic Hammer

Sb40 Top Type Excavator Attachment Rock Breaker Hydraulic Hammer for Digger 4-7 ton

The HWX68 (also SB40)hydraulic breaker with 68mm chisel is a versatile, light-duty attachment designed specifically for compact and mini-excavators. It is widely used in urban construction and landscaping where precision and maneuverability are more important than sheer breaking force.

Key Applications

The SB40 is typically utilized for tasks that require moderate impact energy. Common applications include:

• Urban Demolition: Breaking up indoor concrete floors, stairs, and thin walls during building renovations.

• Road Maintenance: Patchwork repairs on asphalt, cutting through sidewalks, and removing curbs.

• Landscaping: Breaking up boulders or rocky soil to prepare ground for planting or trenching.

• Utility Work: Excavating narrow trenches for gas, water, or electrical lines where larger breakers cannot fit.

• Foundation Work: Cleaning up excess concrete from piles or footings.

Technical Compatibility

To ensure the longevity of both the breaker and the carrier machine, the SB40 must be matched with the correct excavator weight class.

Suitable Weight Class

The SB40 is generally designed for carriers in the 4.0 to 7.0 ton range. Using it on a machine that is too light can cause instability, while a machine that is too heavy may provide excessive hydraulic flow that damages the breaker’s internal seals.

Pin Dimensions: You will need to confirm the pin diameter and the width between the “ears” (bosses) of the excavator arm to ensure the mounting bracket matches.

Common Compatible Models

The SB40 is a “universal” style attachment, meaning it can be fitted to most major brands provided the mounting pins and hydraulic flows are aligned. Typical compatible models include:
