The YG hydraulic drum cutter is an attachment that can be mounted on excavators, backhoes, or other heavy equipment. It features a rotating drum equipped with specialized cutting tools that are driven by a hydraulic motor. These rotating drums are designed to cut through tough materials, including rock, concrete, and asphalt, using a high-speed rotary motion.

Structural composition
- Milling rotor: inlaid with carbide cutter head, directly in contact with the working surface.
- Hydraulic drive system: powered by the excavator hydraulic pump to drive the rotor to rotate.
- Depth adjustment device: hydraulic cylinder controls the milling depth (accuracy can reach ±5mm).
- Protective cover: prevent debris from splashing, some models have integrated material conveyor belt.
- Quick-change connector: suitable for different brands of excavators (such as CAT, Komatsu, Sany, etc.).
How Does a Hydraulic Drum Cutter Work?
The core mechanism of a hydraulic drum cutter relies on hydraulic power to drive a rotating drum. The hydraulic motor is connected to the drum, which features a series of carbide-tipped teeth or tools designed to break down and shear materials as the drum spins. The drum moves in a forward-backward motion, cutting into the material in a highly controlled manner.
The hydraulic system allows for easy adjustment of cutting speed and force, which gives the operator fine control over the cutting process. Depending on the material being cut and the project requirements, the drum cutter can be used for both light and heavy-duty tasks.

Frequently Asked Questions (FAQs)
1. What materials can a hydraulic drum cutter cut?
Hydraulic drum cutters are capable of cutting a wide variety of materials, including rock, concrete, asphalt, and soil. They are versatile and can be used in many different construction and mining environments.
2. Can a hydraulic drum cutter be used for underwater cutting?
Yes, hydraulic drum cutters are designed for use in both dry and underwater environments. Their robust design and sealed hydraulic system allow them to operate effectively in submerged conditions.

3. What industries use hydraulic drum cutters?
Hydraulic drum cutters are used in a range of industries, including construction, mining, tunneling, road maintenance, and demolition. They are particularly useful in projects that require precise cutting and minimal disruption to the environment.
4. How do I maintain a hydraulic drum cutter?
Maintenance typically involves regular inspection of the hydraulic system, checking for wear and tear on the drum and cutting tools, and cleaning the machine after each use. Ensuring that the hydraulic fluid levels are correct and that the cutter is kept free of debris will extend its life.
5. What are the benefits of using a hydraulic drum cutter over traditional methods?
Hydraulic drum cutters offer several benefits over traditional cutting methods, including precision, reduced vibration and noise, improved safety, and environmental benefits. They also provide more control over the cutting process, reducing the risk of damage to surrounding structures.
