2. Small Portable Sand Dredging machine
The small portable sand dredging machine we produce is self-propelled or non self-propelled,portable small portable sand dredging machine. The hull uses dismantle and box-like structure, Its dismantle type can be assembly at working place easily and be transported by road, railway and container accordingly, convenient in installation and working place moving from one to another. The power system can be designed to electric system or diesel engine driving system according to customers’ requirements.Equipment on the small portable sand dredging machine are as belows: traversing device, cutter ladder lifting device, spuds and deck crane. The working process is as following: the cutter head cut the sand and mud underwater to mixture of slurry, then through dredging pump to the pipeline on small sand dredger; at the end the slurry will be discharged by pipeline on land to the required place. Functions of small portable sand dredging machine: dredging river, dredging sand, desilting, reclamation for channels and land, and building roads. Working site of small portable sand dredging machine: sea, port, lake, and river. Soil conditions for small portable sand dredging machine: relative hard soil, harden sand, sludge, sea sand, river sand, clay, mud, and so on. |
Design
| Our small portable sand dredging machine are designed by senior engineer, who have specialized in shipbuilding and dredging work for many years, to guarantee their dredging work performance and practical well. |
