Yunfeng Dredger Company is one of the most reliable manufacturers and suppliers of coarse gravel bucket wheel dredger in China. If you're going to buy the newest coarse gravel bucket wheel dredger made in China, welcome to get quotation from our factory. All customized products are with high quality and low price.
Our Coarse Gravel Bucket Wheel Dredger is intended for dredging projects involving dense soil and gravel-bearing deposits. Its mechanical bucket wheel, equipped with multiple digging teeth, excavates material directly rather than relying on a conventional suction-based cutting arrangement.
Our published Heavy Duty Bucket Wheel Dredger specifications identify dense clay, silt, sandy soil and gravelly soil within the stated soil adaptability range of Class II–V. This provides a technical reference for projects involving compacted and gravel-containing deposits.
Bucket Wheel Excavation System
The dredger uses a rotary bucket wheel fitted with multiple digging buckets and teeth for mechanical excavation.
The published heavy-duty configuration includes:
- Bucket wheel diameter: 2,200 mm
- Bucket wheel drive power: 450 kW / 650 kW
- Hydraulic pumps: Vickers
- Hydraulic motors: SAI
- Hydraulic valves: Rexroth
- Control system: Siemens PLC
The bucket wheel drive power is available in two published configurations. The appropriate arrangement depends on the equipment configuration selected for the project.
