An excavator breaker hammer is a hydraulic attachment that mounts on an excavator and breaks rock, concrete, and reinforced structures through high-frequency percussion. Unlike a bucket that digs or lifts, this tool delivers repeated impact energy directly into hard material. The YG series hydraulic concrete breaker covers chisel diameters from 35mm to 210mm and suits carriers from 0.5 tons to 80 tons. That wide range means one brand can serve a mini excavator doing sidewalk repair and a 70-ton machine breaking basalt in a quarry. The challenge is not finding a breaker. The challenge is matching the right breaker to your carrier, your hydraulic system, and your material.

A 21-Model Lineup That Covers Every Excavator Size on the Market
YG produces excavator breaker hammers for every excavator weight class, and this breadth is the first reason contractors consolidate their purchasing with a single manufacturer. Instead of sourcing different brands for different machines, buyers find one engineering philosophy and one support team across their entire fleet.
Mini Excavator Class (0.5 to 3 tons): The YG350 handles 0.5 to 1 ton carriers at just 40 kg body weight with a 35 mm chisel and 800 to 1,300 bpm blow frequency. The YG400 covers 1 to 3 tons at 53 kg. These compact units fit confined urban job sites, interior demolition, and utility trenching where space is tight and precision matters more than raw force.
Compact Class (1 to 7 tons): The YG450, YG530, YG600, and YG680 cover carriers from 1.2 tons up to 7 tons, with chisel diameters from 45 mm to 68 mm and body weights from 67 kg to 152 kg. This tier handles residential demolition, driveway removal, and small-scale foundation work.
Mid-Range Class (4 to 26 tons): Models YG600 through YG1350 serve 2.5 to 26-ton carriers with chisels from 60 mm to 135 mm. Operating pressure climbs from the standard 90 to 120 bar to 150 to 170 bar on the YG1250 and YG1350. These breakers cover general construction demolition, road breaking, and medium-scale quarry operations.
Large and Heavy-Duty Class (18 to 80 tons): The YG1400 through YG2100 serve carriers from 18 to 80 tons. Chisel diameters reach 140 mm to 210 mm, operating pressure peaks at 200 to 240 bar, and body weights climb to 3,396 kg for the flagship YG2100. This tier tackles primary rock breaking, mining, and large-scale foundation demolition.
Each model in this range carries specific hydraulic flow requirements, so buyers can match their excavator’s auxiliary circuit output to an excavator breaker hammer with confidence. A 15-ton excavator does not need to guess which breaker fits. The YG1250 mini excavator hammer serves 15- to 18-ton carriers with a 125 mm chisel and an 80 to 110 L/min flow requirement. The match is exact, eliminating the trial-and-error approach that wastes time and money on mismatched equipment. Buyers comparing any hydraulic hammer for sale should use this carrier-weight-to-model mapping as their starting point.
Material Durability Built for High-Impact Work Cycles
Demolition work subjects breaker components to extreme repeated stress, and YG addresses this through deliberate material selection across every model in the range.
Q355 Steel Chassis: All YG models use Q355 structural steel for the main body. Smaller models use 10 mm plate thickness, while models from YG400 upward step up to 12 mm, 16 mm plate on the YG400 through YG600 range, and 16 mm on all large models. Q355 steel offers higher yield strength than standard carbon steel, which translates directly into longer chassis life under repeated high-impact loading. When specifying a hydraulic concrete breaker for fleet purchase, this material choice reduces downtime from chassis fatigue.
Chisel Diameter Progression: Chisel diameters scale from 35 mm on the YG350 to 210 mm on the YG2100. Smaller chisels concentrate impact force into a tight contact area for precise breaking of thin concrete, rebar-rich slabs, and secondary demolition work. Larger chisels distribute energy across a wider surface for primary breaking of massive boulders, thick foundation blocks, and hard rock faces. This diameter progression gives every excavator breaker hammer in the YG lineup a clearly defined performance envelope.
Hose Diameter Scaling: Hydraulic hose connections scale proportionally with model size. Compact models use 1/2 inch hoses, mid-range units step up to 3/4 inch and 1 inch, and large models require 1-1/4 inch hoses to handle higher flow volumes without pressure drop. Correct hose sizing ensures the hydraulic circuit delivers full rated pressure and flow to the excavator breaker hammer.
