Who Is This Peruvian Customer and What Is His Core Business?
This real case is from a mature construction contractor based in Lima, Peru. The company has 8 years of local construction experience, focusing on municipal road renovation, urban pipeline trenching, concrete structure trimming, slope shaping, and soft rock milling projects.
As a mainstream mid-sized engineering team in the local market, the company owns multiple excavators, among which the 20-ton crawler excavator is their most frequently used core machine for daily urban and suburban construction.
In Peru’s municipal engineering market, construction requirements are becoming increasingly strict. Traditional blasting and impact breaking are banned in urban areas, and the government requires low-vibration, precise, flat-surface construction methods. Facing stricter construction standards and increasing project orders, the customer’s old construction methods gradually fell behind market demand, pushing him to find a reliable drum cutter attachment.
What Difficulties Did Traditional Construction Methods Bring?
- Extremely poor construction flatness. The impact-breaking method produces uneven broken surfaces, irregular trench walls, and rugged slopes. Every pipeline trenching project needed manual secondary trimming and flatting, wasting a lot of working time and labor costs.
- Severe vibration and safety risks. Hydraulic breakers generate strong impact vibration, which easily cracks surrounding intact roads, building foundations, and buried pipelines. The customer once faced compensation losses due to accidental damage to underground water pipes.
- Ultra-low working efficiency. Breaking hard soil, weathered rock, and old concrete is time-consuming. A standard 100-meter pipeline trench previously required 3 working days, which often delayed project delivery and affected customer reputation.
- Serious dust and noise pollution. Traditional impact breaking produces loud noise and flying dust, which frequently triggered resident complaints and even temporary construction suspensions.
These long-term problems made the customer eager to find a high-precision, low-vibration, high-efficiency drum cutter attachment for excavator to replace outdated breaking tools.
How Did the Customer Find YG’s Professional Drum Cutter Solution?
Trapped by inefficient construction and frequent rework, the customer actively searched for advanced trenchless milling equipment on Google. He browsed a large number of equipment websites and finally landed on YG Machinery’s official website.
After viewing numerous real construction videos, parameter introductions, and global customer cases of YG excavator drum cutters, he found that YG’s attachments are specially designed for municipal renovation, urban trenching, and rock milling scenarios, perfectly matching his 20-ton excavator and Peruvian urban construction environment.
Unlike ordinary accessories on the market, YG drum cutters feature high torque, stable hydraulic output, low vibration, and precise milling, which exactly solve all his existing construction pain points. Therefore, he took the initiative to contact YG’s technical team for model consultation and solution customization.

What Unexpected Excellent Effects Did the New Attachment Bring?
After formal installation and operation, the YG drum cutter attachment brought many unexpected optimized results far beyond the customer’s expectations, with obvious digital improvements.
- Construction efficiency increased by 55%. The original 100-meter trench took 3 working days; now it only takes 1.3 days to complete. The monthly construction volume increased significantly, helping the customer take more government municipal orders.
- Zero rework rate and perfect flat forming. The rotary milling method creates smooth and neat trench walls and slopes, eliminating manual secondary trimming. The one-time forming pass rate reaches 100%, greatly saving labor and time costs.
- Zero damage to surrounding facilities. Low-vibration cutting avoids vibration cracks on roads and buildings. No more pipeline damage accidents, eliminating hidden compensation risks.
- Greatly improved on-site environment. The sealed rotary cutting structure reduces dust and noise, eliminating resident complaints and construction suspensions, ensuring stable project progress.
- Wide application flexibility. One machine meets multiple working needs, including trenching, concrete removal, rock shaping, slope trimming, and foundation finishing, greatly improving the utilization rate of the 20-ton excavator.
