Malaysia Client Case Study — Excavator Drum Attachments
A tunneling and road construction company in Malaysia had long grappled with issues of low construction efficiency, excessive noise, and high vibration levels. After adopting YG excavator drum attachments, the company successfully replaced its breakers and buckets; this resulted in an excavation efficiency increase of approximately 30%, while simultaneously achieving a significant reduction in both noise and vibration—ultimately saving the project valuable time and labor costs.
What are Drum Cutter Attachments for Excavators?
A drum cutter is a kind of attachment for excavator. It can cut rock, concrete, or frozen ground with rotating drums equipped with picks. It has different features such as no torsion system, wear-resistant plates, power boost, and high oil temperature reducing device.
The Rotary Horizontal Drum Cutter for the Excavator machine can be installed on any type of hydraulic excavator. It is easy to use and can effectively replace common configurations such as buckets, breakers, and hydraulic shears.

Excavator hydraulic milling cutter – Applications
The excavator drum cutter is widely used in construction projects. For example, tunnels, dam bottom excavation, road artificial slope excavation, iron tower foundation, continuous underground wall stripping, coral stone excavation, weak foundation improvement, tree plant treatment, trench excavation, work in steel works, improvement of contaminated soil, asphalt stripping, quarry work, building demolition work, underwater excavation, canal expansion, permafrost excavation, etc.
Malaysian clients utilize horizontal milling excavators for bridge foundation excavation and underground pipeline construction, while vertical milling excavators are employed for cutting concrete walls, thereby ensuring construction precision and safety.
Feedback from a Malaysian Client:
“YG’s drum-type excavator attachments have completely exceeded our expectations. The equipment is easy to operate, significantly boosts construction efficiency, and—at the same time—drastically reduces noise and vibration, making it perfectly suited for our construction needs in urban and tunnel environments.”
Drum Cutter for Tunnel and Road Construction
For this Malaysian project, the excavator drum cutter was used for controlled rock and concrete excavation in tunnel and road construction. Compared with conventional breaking methods, the rotating cutting drums allowed the contractor to remove material more precisely while helping reduce noise and vibration in confined work areas.
Drum Cutter vs Hydraulic Breaker
Both drum cutters and hydraulic breakers are excavator attachments used for rock and concrete excavation, but they work in different ways.
| Feature | Drum Cutter | Hydraulic Breaker |
|---|---|---|
| Working method | Rotating cutting drums with picks | Percussive impact from a chisel |
| Material removal | Controlled milling and cutting | High-impact breaking |
| Noise & vibration | Generally lower | Generally higher |
| Cutting control | Suitable for more controlled material removal | Suitable for impact-based breaking |
| Typical applications | Tunnels, slopes, trenching, concrete milling | Rock breaking, demolition, foundation work |
For projects where controlled excavation, lower noise and reduced vibration are important, a drum cutter can be a suitable alternative to conventional breaking methods. The right attachment still depends on the material hardness, excavation requirements, excavator specifications, and site conditions.
