Ask a FLUMP Expert. Seven ways to Secure your Traverse System

Posted by Elizabeth Kaiser on Thu, Jul 28, 2011 @ 08:07 AM

The propulsion and traverse systems are critically important to the operation of an unmanned, cabled dredge. The FLUMP, SRS Crisafulli's unmanned dredge, propels itself along a traverse cable connected to lateral cables at opposite sides of the lagoon, configured at 90 degrees to the traverse cable.

The FLUMP's drive system is onboard.  SRS Crisafulli's FLUMP Specialist, Senior Applications Engineer Eric Lillberg, explains seven ways to secure the lateral traverse cables to land, on opposite sides of the lagoon.

The standard method is to drive three 48" long stakes into a triangular steel base plate on each of the four corners of the lagoon or pond.  From the four corners, wire rope winches are connected to each lateral cable, each of which is connected in turn to the traverse cable that runs the length of the lagoon.  The corner winches can exert 2,000 lbs. of tension into the cable system. 

Normally, this method provides more than adequate results, depending on the length of the traverse cable.

Even at 700 lbs. of tension, however, a base plate can be pulled out of soft ground, which leads us to Method #2, a daisy chain setup with multiple stakes connected by chains or cables.

Method #3:  In more permanent installations the use of concrete bollard posts is an economical solution.

Method #4: A motorized trolley system mounted on a steel rail structure. A rail structure with a motorized trolley system is the preferred method for permanent installations.  The rail structure adds cost to the system, but can result in a substantial reduction in ongoing operator cost thereby improving the overall return on investment (ROI) from the dredging system.  Traverse 3 resized 600

 

Method #5:  When the lagoon is surrounded by hard packed or rocky terrain, other methods have been utilized, including large concrete blocks, about 32" x 32" x 64" and weighing approximately 5700 lbs.  Depending on the lay of the land, it may take some jockeying to prevent the blocks from sliding, once tension is applied.

Method #6:  We have drilled holes in existing rock and concrete structures to set anchors. 

Method #7:  A not so common, but equally effective approach is to use two motor vehicles, one on each side of the lagoon.  Skilled drivers move the two vehicles in perfect parallel, enabling the system to work with no adjustment to the traverse system. Traverse 5 resized 600

 

No matter what the method, a taut cable is essential to effective unmanned dredging.

Why Zambia? SRS Crisafulli Mine Dredges Provide Useful Options.

Posted by Elizabeth Kaiser on Thu, Jul 21, 2011 @ 08:07 AM

African Growth and Opportunity Act, or AGOA Forum 2011, Lusaka, Zambia was an odd destination.  But that is where a Montana delegation of Small and Medium Enterprises, or "SMEs" went in early June, 2011.  The overarching goal of the AGOA Forum is to increase US - Africa trade volume.  Why would SRS Crisafulli participate?  SRS Crisafulli Dredges provide reliable and effective water management solutions to the mining industry in Africa.  Many African countries, including Zambia, are actively mining gold, copper and uranium, all of which need water management tools.  The Crisafulli dredges provide useful options for environmental managers at mines throughout the world.

Further, the classic Crisafulli trailer pumps, so useful to the US Army Corp of Engineers in dewatering US properties submerged in the Floods of 2011, may be of service to African growers managing water resources.

"I am excited to return to Zambia.  Next time I will visit the Zambian Copperbelt itself, take a helicopter ride over Victoria Falls, and go on a traditional safari.  In the meantime, I packed my bag with Zambian honey, and am buying imported South African wines from my neighborhood wine cellar," reports SRS Crisafulli attendee, President and CFO Laura M. Fleming.

Dredge Dealer Dairy Specialists Wins Business Ethics Award

Posted by Elizabeth Kaiser on Fri, May 20, 2011 @ 09:05 AM

Dredge DealerDairy Specialists, an SRS Crisafulli agricultural dredge dealer for more than two years, was awarded with the Colorado-based CEBA Bill Daniels Business Award in March for conducting every aspect of its business with the highest of ethical standards.

Companies who receive the CEBA award are nominated by customers, vendors and organizations in the community at large.

When asked why Dairy Specialists was selected for this award, Owner Randy Sorensen had the following response:

“I think the way we choose to do business really resonates with people.

Dairy Specialists’ mission statement serves as the framework for how our company operates.

Mission Statement:

Dairy Specialists will be the Rocky Mountain Region’s Premier Provider of Dairy Construction, Supplies and Service by providing:

  • The Best Designs in the Marketplace
  • The Best Construction Quality & Time to Completion
  • The Best Service & Products Available
  • The Best Internal Systems in the Industry
  • The Best People in The Business
  • The Best Value for Our Customers…Our Partners

 

We will be Outstanding Citizens of the Community that Makes Our Business Possible.

Creating a culture driven by the mission statement is a function of ethical, principled leadership at Dairy Specialists. The Leadership Team models the way for all our employees by framing every activity and decision it makes around the questions, “Is it the right thing to do?” and, “Does it drive us towards completion of our mission?” It’s simple, but it seems that, when framed in these terms, every issue, be it with vendors, customers, employees or the community at large yields consistently fair, quality outcomes. Our employees have quickly embraced this approach to doing business and feel empowered to make decisions and act accordingly knowing they will be supported.”

Dairy Specialists, one of three honorees, was selected from a group of 27 finalists, including 13 companies, seven non-profits and seven individuals representing a wide range of industries and community organizations from hospitals and youth agencies to law firms and financial institutions.

Dairy Specialists is one of the largest and most innovative dairy service and supply dealerships in the country. Supplying commercial dairy farms with innovative parlor designs, new construction, remodels and state-of-the-art dairy equipment and dairy waste management technology.

Dairy Specialists consult with their Dairy Customers for SRS Crisafulli’s Trailer Pumps and Remote controlled FLUMP Lagoon Dredges.

As with the agricultural industry , 2008, 2009 and early 2010 were 30 of of the worst months in the last thirty years for the entire dairy industry and specifically for dairy farmers in Colorado. Declining milk prices, increased feed and energy costs, coupled with the failure of one of the largest local dairy industry lenders, New Frontier Bank, led to the perfect storm for Colorado dairy farmers.

The opening of a new Laprino Foods Plant in Greeley will ultimately lead to the need for additional milk generation in the state, which will open up new opportunities for Dairy Specialists to participate in the design and construction of new dairy parlors as well as in the expansion of existing facilities. Ongoing innovations and involvement in bringing green energy and efficient waste management technologies to agriculture and the community as a whole, represent realistic opportunities for growth. The prospects for a good year in 2011 are looking up for the Colorado Dairy Industry.
