W&S Introduces Rugged Small Dredge

March/April 2003 issueW&S Dredge Manufacturer in Greenbush Michigan has been in business for 35 years designing and manufacturing small dredges. The company has built several dredges for small projects such as one eighth of an acre or larger ponds but these units ended up too heavy too bulky and too time consuming and costly to move in and out of the job site locations. The company has solved all these problems with a new dredge Model D-16-2. Read More

W&S Introduces Rugged Small Dredge

March/April 2003 issueW&S Dredge Manufacturer in Greenbush Michigan has been in business for 35 years designing and manufacturing small dredges. The company has built several dredges for small projects such as one eighth of an acre or larger ponds but these units ended up too heavy too bulky and too time consuming and costly to move in and out of the job site locations. The company has solved all these problems with a new dredge Model D-16-2. There are three or more characteristics that helped achieve our goal said Tom Stojsik company president. First W&S and Pekor Pumps Inc. have developed a completely new lightweight heavy-duty six-inch dredge pump. This Ni-Hard pump is designed much like the larger sand and gravel pumps with a head capability of 250 feet. The main reason W&S choose Pekor Pumps Inc. is due to our experience over the last 25 years in receiving excellent product quality and service. Second a lightweight dredge pump was needed to achieve the quality and performance as in our larger dredge models. This has been accomplished. Third we achieved dredge mobility with the specially designed undercarriage and axle assembly which provides a roll-in roll-out system he said. The dredge is perfect for golf courses shrimp farms small marinas small sand slurry operations fishponds small clean up projects and much more said Stojsik.The new dredge model weighs less than 20000 pounds and is equipped with a powerful little cutterhead. We have referred to the word little as this dredge has been downscaled from our larger dredging units in order to handle smaller jobs said Stosjik. During our testing period of this unit we deliberately placed the dredge in severe conditions to find its weaknesses. The testing site was a sand and gravel pit containing large stones. Keep in mind this dredging unit has no business being placed in this type of dredging condition as its size does not allow for the passage of large stones. The dredge has been manufactured only for sand and small stones. However the performance during the testing phase in this particular situation went far beyond our expectations he said. Other unique and special features are the removable engine house cover and control cabin. The control cabin has been well insulated for noise reduction. This model is also equipped with lightweight aluminum side tanks which can be easily handled by one man. There are 10 side tanks and two main hull (full length) foam filled compartments. Three additional compartments have been placed under the engine pump and control house for a total of 15 individual compartments. Package prices for the Model D-16-2 vary between $127000.00 and $158000.00. Read More

Dewatering With Tubes Opens Market

Small projects that used to defy economic justification because of high dewatering and handling costs can now go ahead. Small dredges pump into geotextile tubes that contain the material in restricted areas and allow it to dewater leaving a sausage of nearly-dry solids that can be hauled away in trucks. Read More
