A demolition company in a certain location in Australia was contracted to dismantle a multi‑storey concrete building in a densely populated area. Strict local regulations prohibited loud impact breakers due to noise concerns. The contractor needed a quiet yet powerful tool that could crush reinforced concrete and separate rebar efficiently. Traditional breakers were too noisy, and excavator shears struggled with thick concrete sections.
After evaluating several options, the project manager discovered YG’s hydraulic pulverizer excavator. He wanted a tool that could mount onto his 28‑ton excavator. YG recommended the YG1000 model.
Technical Parameters Of The Hydraulic Pulverizer Excavator
YG offers five models of this attachment. Based on the customer’s 28‑ton excavator and typical concrete thickness (up to 400mm), YG selected the YG1000. Below are key specifications:
| Model | Unit | YG400 | YG600 | YG800 | YG1000 | YG1700 |
| Total length | mm | 1642 | 1895 | 2168 | 2218 | 3150 |
| Total width | mm | 1006 | 1275 | 1376 | 1598 | 2100 |
| Blade length | mm | 120 | 150 | 180 | 200 | 240 |
| Max Opening Height | mm | 587 | 718 | 890 | 1029 | 1400 |
| Upper Jaw Width | mm | 215 | 280 | 290 | 380 | 400 |
| Lower Jaw Width | mm | 458 | 586 | 588 | 720 | 812 |
| Max Shear Force | kn | 380 | 650 | 1650 | 2250 | 2503 |
| Working Pressure | Bar | 280 | 320 | 320 | 320 | 320 |
| Weight | kg | 670 | 1350 | 1750 | 2750 | 4709 |
| For Excavator Weight | ton | 6-9 | 10-15 | 18-26 | 26-30 | 50-80 |
The YG1000 hydraulic pulverizer excavator delivers 2250 kN of shear force at 320 bar. This machine features a 360° rotation motor for precise positioning.
How This Concrete Pulverizer Attachment For Excavator Performed On Site
The Australian contractor mounted the unit onto his 28‑ton excavator. The first test was on a 300mm thick concrete column with heavy rebar. Results were impressive:
- Crushing power: The pulverizer crushed the column into small pieces in under 3 minutes. The 2250 kN shear force cut through rebar like wire.
- Noise reduction: Noise levels measured 40% lower than those of a hydraulic breaker, satisfying council restrictions.
- Material separation: The pulverizer crushed concrete while stripping rebar, allowing clean steel recovery for recycling.
The concrete pulverizer attachment for excavator also handled floor slabs and foundation walls. The operator appreciated the precise jaw control for selective demolition.
Customization For Australian Regulations And Conditions
YG engineers studied Australian safety standards and working conditions. Customizations included:
- AS/NZS compliant decals and warning labels on the hydraulic pulverizer excavator.
- Pressure relief valve to prevent overload on the excavator’s hydraulic system.
- Reinforced wear plates made of high‑wear steel for Australian abrasive aggregate.
- Quick‑coupler compatible mounting bracket to match the customer’s existing coupler system.
For the attachment, YG also provided a full set of spare jaw plates and shear blades. The concrete pulverizer attachment for excavator was painted with high‑visibility yellow and had reflective strips for jobsite safety.
Tangible Results After Using The Hydraulic Pulverizer Excavator
After six weeks of daily operation (8 hours/day, 5 days/week), the Australian contractor recorded measurable gains:
- Demolition speed increased by 60% compared to using a breaker with separate shears.
- Rebar recovery reached 95% purity, fetching premium scrap prices.
- Noise complaints dropped to zero – the machine operates quietly.
- Excavator fuel consumption decreased by 25% because the pulverizer uses less hydraulic flow than a breaker.
The pulverizer paid for itself in six months. The contractor has since ordered a YG600 model for his 12‑ton excavator used in smaller residential jobs.
Smooth Cooperation And Final Conversion
YG provided 3D installation drawings and crushing sequence videos. Sea freight was arranged from China to a major Australian port. Remote video support via WhatsApp guided the first jaw change and pressure adjustment. The pulverizer came with a one‑year warranty and a free blade resharpening template.
