When it comes to dredging, the age-old debate of hydraulic vs. mechanical dredgers has experts and industry insiders divided. These two giants of the dredging world each boast their unique strengths and weaknesses, and choosing the right one for your project can be quite the challenge.
In this post, we'll be comparing hydraulic and mechanical dredgers to help you make an informed decision on the most suitable dredging solution for your needs.
- Hydraulic Dredgers
- Mechanical Dredgers
- Which dredger is the Best?
Hydraulic dredgers act as a giant, underwater vacuum cleaner to clean and remove sediments. By sucking up a combination of sediment and water, hydraulic dredgers create what is called a “slurry.” This slurry is moved from the surface and then onto the surface via a pipeline or tube.
This is widely considered the most effective method of dredging when the environment and the ecosystem of the dredging site is of major concern. It is preferred because it prevents most of the contaminated sediments from being dispersed or released into the nearby water source. While this is a major advantage to hydraulic dredgers, they do have their limitations.
Because of their design, hydraulic dredgers are excellent for moving loose soils, sands. Silt, gravel, or rocks can cause undue wear and tear on the hydraulic system.
Mechanical dredging necessitates the use of heavy equipment to dig up the bottom of a water source, and move it. This equipment can be moved to the job site by a barge, or the body of water can be drained, allowing the equipment to move to the site on its own. Some specialized mechanical dredging equipment can drill or dig up the dirt.
While mechanical dredging is the most commonly rented form of dredging machinery, that does not mean it is always the most effective. Because this form of dredging requires a bucket or digger to impact and shovel away the sediment, there is a higher chance of contaminated materials within the sediment to be dispersed into the water surrounding it. The contaminated soil can fall out of, or through the bucket, and spread further into the water.
Which dredger is the Best?
Both forms of dredgers have their benefits. While hydraulic dredgers are precise, and fast, they aren’t able to take on heavier materials. Mechanical dredgers are cumbersome and imprecise, but they can move fast quantities of heavy materials with minimal effort. One might be better suited to your dredging job than the other, but often using a combination of the two leads to the best outcomes.
Dredgers are ideal for a variety of projects because of their ability to move, and remove materials like trash, gravel, and sediment. Dredging can help keep waterways, like rivers and streams clean and help restore their beaches and land from the effects of erosion. Additionally, they can be used to maintain the stability of harbors, ports and marinas.
