Overview
Quick answerTop-mounted hydraulic hammer for straight-down breaking on 6–36 t excavators. 75–155 mm chisel, 20CrMo body, full in-line force transfer.
On a top-type breaker the bracket sits on top of the power cell, so the hammer hangs in line with the dipper arm. Force travels straight down the chisel, which makes top types the preferred choice for vertical breaking in pits, foundations and mining benches where precise down-pressure matters.
Typical applications
- Pit and foundation excavation
- Mining benches
- Bridge pier demolition
- Boulder reduction
Scope of supply
Breaker body, mounting bracket for your carrier, 2 hoses, 2 chisels (moil/flat/blunt to choice), nitrogen bottle and charging kit, tool box, operation manual.

Key features
In-line force transfer
The bracket centres the blow on the arm axis for efficient vertical breaking.
Reinforced top cap
Thick top bracket plate with bushings resists side loads in pit work.
Wide flow window
Valve tuned for stable impact across the full rated flow range.
Optional auto-greasing
Factory-fitted greasing pump available for long shifts.

Frequently asked questions
Is a top type stronger than a side type?
With the same power cell blow energy is identical; top type simply transmits it more efficiently when breaking vertically.
Can you make the bracket for my coupler?
Yes – brackets can be made pin-on or for your hydraulic coupler.
How do I choose the right hydraulic breaker size?
Match three numbers: your excavator operating weight, the auxiliary hydraulic flow (L/min) and the relief pressure (bar). The breaker’s recommended carrier range and flow window must cover your machine. Send us the carrier model and we will confirm the model and mounting bracket.
What is the difference between side, top and box type?
Side type is the most compact and economical; top type mounts in line with the dipper arm for straight-down breaking; box (silenced) type wraps the power cell in a damped housing for lower noise and better protection in urban work.
