Introduction: 

Helm Tower Drum Cutter (HDC series) use the worldleading hydraulic technology. It could install to any types' of hydraulic excavator and could effectively replace mining, tunneling, profile correction, grooving in channel surface, asphalt concrete pavement milling, rock soil milling etc. 
Our drum cutter devided into two differenct structures, they are horizontal drum cutter (HDC series) and vertical drum cutter (HTC series). 

Working principle and advantages: 

Horizontal drum cutter is the structure, which could output directly. The motor could be installed to the rotary part directly, which can deduct the gear transmission. In this case, the real power of the motor could extend to the toppest and reduce the energy consumption in transmiting. Another hand, the hydraulic oil merge together, it can avoid the messy of the pipelines. One pipeline inlet and another pipeline outlet, two piplines only. It keeps a straight way with the breaking hammer and do not need any other retrofits. It is more powerful and more simple in installing. 

Helm Tower Horizontal Drum Cutter series: 
HDC05 (Suitable Excavator: 3-16 tons)
HDC11 (Suitable Excavator 12-18 tons)
HDC18 (Suitable Excavator 18-30 tons)
HDC35 (Suitable Excavator 25-40 tons)
HDC50 (Suitable Excavator 35-55 tons)

Vertical drum cutter includes 3 modules, they are motor, gear box and cutting drum. The motor drives the gear box and then the gear box drives the cutting drum. This structure can enable the vertical drum cutter to cut with a bigger cutting force and could reduce the hydraulic oil leaking risk. 

Helm Tower Vertical Drum Cutter Series: 
HTC08
HTC18
HTC35

Features: 
1. Robust - long lasting, low maintenance
2. Strong - maximum cutting power to penetrate the rock
3. Reliable - direct drive cutting technology
4. Extremely accurate scaling/grinding/profiling
5. Direct reuse material as backfill
6. Lower vibrations reduce fatigue
7. Quiet operation in noise sensitive area

Technology advantage: 
1. Two main parts consist of high torque hydraulic motor and cutting drum without gearbox. 
2. Machines from 2 tons to 40 tons. 

Application: 
1. Trench and pipeline construction
2. Demolition and concrete work
3. Rock breaking in mining site
4. Contouring, profiliing, building renovation
5. Tunnel construction
