For dredging, consider the type of sediment and the project’s scale. If the sediment consists of hard materials like rock, a heavy-duty excavator would be more suitable.
For softer materials like silt or sand, a standard hydraulic excavator might suffice. The size of the project also matters. Larger projects may require bigger, more powerful machines, while smaller ones might only need mini or midi excavators.
Efficiency is key, so consider an excavator with high fuel efficiency and easy maintenance. Remember, safety features should never be compromised.
Hope this helps in your decision-making!
