Komatsu’s hydraulic hammers are perfect for demanding tasks such as breaking concrete, rock, and asphalt, as well as excavating in hard soils. These hammers deliver maximum power and efficiency while being gentle on the machine, ensuring a longer lifespan.

Benefits of Komatsu hammers

• Optimized for Komatsu machines – Perfectly suited for Komatsu excavators.
• Compatible with other brands – Can also be used on a wide range of other machine types.
• High impact power – Ideal for breaking rock, concrete, and asphalt.
• Low vibration levels – Shock-dampening box consoles on JTHB-G models and rubber/poly suspensions on JMHB-H and -V models reduce strain on both machine and operator.
• Extended lifespan – Automatic lubrication system protects against dust and debris, preventing premature wear.
• Noise reduction – Fully enclosed soundproofed housing minimizes noise compared to open breakers.
• Versatility – Dual work modes allow adjustment of frequency and impact force for different rock types.
• Compact power – Lightweight models with single power cells (without heavy tie rods) improve power-to-weight ratio.
• Standard features – Automatic greasing, blank-firing protection, rotatable hose couplings, and reinforced design for durability.

To ensure optimal performance and extend hammer lifespan, regular maintenance is essential:

• Check for leaks regularly.
• Inspect side bolts for wear and tension.
• Check for play between bushings and chisels.
• Measure wear on the chisel.
• Ensure wedge locks are not reversed.
• Verify proper clamping between hammer and hammer bracket.
• Test side bolts with a metal sound test—all bolts should produce a uniform sound.
• Recommended service interval – Once per year.
• For frequent hammer use, hydraulic oil change intervals should be halved.
