Overview

Quick answerCompact side-type rock breaker (SB series) for 0.8–36 t excavators. 20CrMo piston, 35–155 mm chisel, CE certified, bracket made to your carrier.

The side-type hydraulic breaker is the workhorse of our range. The power cell is mounted on a side bracket, which keeps overall length short, gives the operator a clear view of the chisel and makes the hammer easy to service. It is the most cost-effective choice for trenching, foundation work, road repair and secondary breaking in quarries.

Typical applications

Trench and foundation breaking
Road and pavement repair
Secondary breaking in quarries
Concrete demolition

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

Short, rigid side bracket

Through-bolted side plates keep the hammer close to the arm for maximum control and lower bending load.

Forged 20CrMo piston

CNC-ground and carburised for hardness at the surface and toughness in the core.

Nitrogen-assisted blow

Back-head nitrogen charge adds blow energy without extra oil consumption.

Easy field service

Through bolts, bushings and chisel pins are accessible without removing the hammer.

Frequently asked questions

Which side-type model fits a 20 t excavator?

SB70 (135 mm chisel) is the standard match for 18–25 t; SB81 (140 mm) suits heavier 20–30 t machines working in hard rock.

Can I change it to a top or box type later?

The power cell is shared; we can supply a top bracket or a silenced box housing as a conversion kit.

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.
