RW hydraulic cutter heads are ideal for trenching, profiling rock and cement walls, tunneling, quarrying, demolition, dredging, finishing operations and underwater works. They are highly effective where conventional excavation systems are too weak and percussion systems have little effect. Their quiet operation allows them to be put to work near sensitive areas (residential zones, hospitals, schools, bridges and infrastructure). Especially recommended for finishing operations, where high precision, minimum disturbance and optimum aesthetic result are required.
A Hydraulic Drum Cutter is a powerful excavator attachment used for precise excavation, trenching, tunneling, profiling, and demolition. It features rotating cutting drums fitted with picks or teeth that grind away rock, concrete, or frozen ground. Here's a quick overview:
🔧 What is a Hydraulic Drum Cutter?
A Hydraulic Drum Cutter (also known as a rotary drum cutter or rock grinder) is typically mounted on excavators or skid steers. It utilizes hydraulic power from the carrier machine to rotate two cutting drums equipped with replaceable carbide-tipped picks.
📌 Key Features:
- Precision Cutting: Ideal for contouring rock and concrete with minimal vibration.
- Low Noise and Vibration: Safer for urban areas and sensitive job sites.
- Versatility: Works on soft to medium-hard rock, concrete, and frozen ground.
- Underwater Capability: Some models work underwater with no special modifications.
🔨 Common Applications:
- Trenching for utilities or pipelines
- Concrete wall and slab removal
- Tunnel profiling
- Road and bridge refurbishment
- Quarrying and mining
- Underwater demolition
🏗️ Compatible Machines:
- Excavators (5–70 tons)
- Skid steers (with high-flow hydraulics)
🔍 Why Use a Drum Cutter Instead of a Hydraulic Breaker?
- Less vibration and more control
- Smoother finish for profiling tasks
- Better for confined spaces
- Reduces micro-cracking in remaining structures
Description
Rapid impact compaction (RIC) is an intermediate compaction technology from shallow to deep compaction and bearing capacity while minimizing settlement and the risk of liquefaction in loose sands. .
