A major infrastructure company based in Hanoi, Vietnam recently purchased the YG-3 excavator crusher bucket to handle dense basalt rock and tough demolition waste. The client needed a fast, reliable, and mobile solution to crush raw materials directly on-site for a highway expansion project in Dong Nai province. Traditional stationary crushing plants required high transportation costs, complex regional permits, and heavy logistical planning.
By mounting our specialized crushing attachment onto their existing 22-ton crawler excavator, the contractor completely eliminated the need for secondary hauling vehicles. This choice allowed them to process thousands of tons of material right where it lay. The team saved valuable project time and kept their operations moving forward without relying on outside sub-contractors or third-party transport teams.

Project Background And Field Application Challenges
The construction site in Southern Vietnam presented unique geological and climate challenges that demanded tough equipment characteristics. Heavy rains often turned the ground muddy, making it hard for heavy dump trucks to move material back and forth. Understanding these specific field conditions helped us deliver the ideal configuration for the contractor.
- High Material Hardness: The project site contained high-density volcanic basalt with high compressive strength. This tough stone quickly ruins standard excavator buckets and requires heavy-duty jaw plates.
- Space Limitations: The narrow highway right-of-way and nearby active traffic lanes prevented the setup of large, traditional stationary jaw crushers.
- Strict Granulometry Demands: The base layer of the road installation specified an aggregate size strictly between 40mm and 80mm to meet regional transportation standards.
- High Fuel Costs: Transporting raw stone to a central crushing plant 25 kilometers away significantly lowered the project profit margins and wasted truck fuel.
- Weather Disruptions: Frequent heavy tropical downpours often halted traditional trucking, meaning the team needed an all-weather solution that could work in tight spots.

Why The Vietnam Contractor Selected The YG Crusher Attachment for Excavator
The procurement team evaluated multiple international brands from Europe and Asia before choosing the YG-3 crusher attachment for excavator. Our equipment offered distinct technical advantages, a competitive price point, and matched their 22-ton operating machinery perfectly without requiring expensive retrofits.
- Perfect Hydraulic Matching: The YG-3 requires an oil flow of 140 liters per minute and a working pressure of 220 bar. This matches standard 20-to-25-ton excavators without requiring auxiliary hydraulic boosters or extra power packs.
- Adjustable Output Range: The output setting adjusts easily from 15mm up to 130mm. This feature allows the operator to shift from fine aggregate production to coarse sub-base materials in just minutes using simple hand tools.
- Optimized Throat Opening: With opening dimensions of 740mm length by 510mm height, the bucket accepts large rock pieces easily without bridging, jamming, or clogging the feed area.
- High Structural Efficiency: Weighing 2.3 tons with a load capacity of 0.66 cubic meters, the bucket maintains excellent machine balance and excavator stability while delivering a maximum production rate of 31 cubic meters per hour.
- Heavy Duty Material Build: YG uses high-strength steel for the entire bucket frame. This layout prevents warping and twisting when the powerful hydraulic jaws crush the hardest river stones and rocks.

Operational Feedback On The Excavator Rock Crusher Bucket
After 400 hours of continuous operation in the field, the job site supervisor sent our engineering team an updated operational report. The digger crusher bucket changed their entire material handling workflow and helped them beat their original project timeline.
- Daily Production Capacity: The attachment processed an average of 240 cubic meters of basalt per 8-hour shift, meeting the site demand easily and keeping the road base crews busy.
- Superb Wear Resistance: The high-manganese steel jaw plates showed minimal wear despite processing highly abrasive volcanic rock for weeks on end.
- Massive Cost Reductions: On-site processing reduced total material transportation costs by 42% and minimized regional landfill disposal fees because they reused the old road concrete.
- Operator Control: The simple mechanical adjustment mechanism allowed easy control of the output aggregate size directly in the field, so operators changed sizes without leaving the work zone.
- Quick Installation Time: The operators could connect or disconnect the bucket attachment in less than twenty minutes using their standard quick-coupler setup.
