County of Bergen Looks to a Putzmeister Telebelt® TB 130 for Efficiency and FlexibilityAlexander Wagner Co., Inc.’s TB 130 saves time and increases job site efficiency on Dahnert’s Lake’s remediation
STURTEVANT, WI (February 1, 2008) – The Putzmeister Telebelt® TB 130 telescopic belt conveyor owned by Alexander Wagner Co, Inc. (Alexander Wagner) had no problem getting to the bottom of a tricky placement job Dahnert’s Lake in Garfield, New Jersey back in September 2007. The TB 130 easily conveyed 4,200 cubic yards of controlled fill and 3,500 tons of stone for the County of Bergen’s Dahnert’s Lake re-lining.
According to Matthew DelPreore, Vice President for River Edge, New Jersey-based Let it Grow™, Inc. (Let it Grow), says the lake was re-lined as a part of an overall rehabilitation to Dahnert’s Lake Park. Let it Grow is the general contractor for this project. In addition, Neglia Engineering Associates, engineer for the County of Bergen and John Biale, County Project Manager, were on-site as well during the project.
A few factors played into the substandard condition of Dahnert’s Lake.
“There was no original lining for this lake,” says DelPreore. “In addition, incoming storm water to the lake wasn’t filtered by any type of system for years, and soil along with leaves built up at the lake’s bottom, which in turn decreased water depth and created murky water.”
“Many people visit this park every day and we want to keep them coming back,” says DelPreore. “This rehabilitation is a part of what will hopefully keep people utilizing the park and all of the things it has to offer.”
During the rehabilitation project, the existing lake water and that entering at its north end were diverted out and around the lake using bypass piping and eight-inch pumps. The controlled fill and stone was able to then be conveyed by the Telebelt right onto the lake bottom.
Gerry Santoro, Let It Grow’s General Superintendent, recommended Alexander Wagner and their TB 130 for this project based on his positive experience with the machine in the past.
Alexander Wagner arrived on-site with their TB 130 in September 2007 and was on-site for seven days, eight hours a day, conveying controlled fill and stone for the re-lining of the 360,000-square foot lake. The TB 130 conveyed about 75 percent of the controlled fill and stone needed for this project.
“This was our first time working with Alexander Wagner, but we had heard their equipment is nothing but reliable and resilient,” comments Santoro. “With their TB 130 we were able to convey the controlled fill and stone; without the conveyor it would not have been possible because the dump trucks and bulldozers would have been too heavy to place the material. They would have started to sink into the lake’s bottom.”
Step by Step
“The TB 130 conveyed the controlled fill on top of the liner, and then our small dozer would spread the controlled fill to make it as level as possible,” says DelPreore. “After the controlled fill was placed, Alex Wagner’s TB 130 would convey and place the stone.
“It was very important the stone was placed on top of the controlled fill on the same day because the lake liner had to be protected from the rain, as well as the natural springs that were seeping through sections of the uncompleted parts of the lake re-lining. The stone had to cover all of the controlled fill to ensure the natural springs wouldn’t flow into the finished sections and saturate the completed sections. This would result in muddy and unworkable conditions the next day.”
To control the water flow of the natural springs, according to DelPreore, pumps were used during the working hours but not at night – yet another reason for making sure the stone was placed on top of the controlled fill on the same day.
Reaping the Benefits of a Single, Yet Powerful Machine
“We knew that our TB 130 was the perfect fit for this project,” says Don McElroy, the Telebelt operator on this job for Alexander Wagner. “Our TB 130 is the master at placing one type of material on a job site and then turning around in the next half-hour and placing a completely different type of material on the same site from the same or different location.”
Throughout the seven days on the project, the TB 130 was positioned in different locations to ensure the boom would reach at a maximum distance across the lake for whichever section would be worked on that day.
“In some spots, depending on which section of the lake was being handled, we were able to reach out up to about 130 feet with the five-section TB 130 boom,” says McElroy, “We were able to make this happen by removing the discharge boot, tremie and end hose. This allowed for us to extend the boom to what the job site required.
“The TB 130’s reach with the discharge boot, tremie and end hose on is impressive itself at 126' 6", but because of the versatility of the machine, it gives us the option to reach even farther if need be. This benefits not only us, but the contractor as well.”
“In addition, the 18-inch (457mm) belt width of the TB 130 is a big asset for us – it handled both materials easily,” comments McElroy.
Setup and tear down convenience with the TB 130 was a crucial element on this job site due to the urgency in ensuring the controlled fill and stone were placed for all sections of the lake by the end of the work day.
“With the combination of the TB 130 setting up and tearing down quickly, placing the material at high volumes and precise placement of the material, we were able to complete each day’s work with less manpower,” says DelPreore. “This was a big advantage for us because on some days the machine had to move multiple times, as much as up to 60 feet away for where it was originally set up.”
In addition to their TB 130, Alexander Wagner also had their Putzmeister front-end loader hopper on-hand at the job site. Ideal for loose material such as controlled fill or bulk material like stone, “the front-end loader hopper easily gobbled up the large capacity of controlled fill and stone,” notes McElroy. The front-end loader hopper can handle material capacities up to 0.8 yd3 (0.6m3).
A Machine of Many Trades
With the Dahnert’s Lake project complete, the entire project wrapped in November 2007. Alexander Wagner has done multiple lake and pond remediation projects in the past year, with several currently in progress. He also says their TB 130 and TB 110 can place many types of materials.
“From concrete and controlled fill to gravel and stone, our Telebelts can really convey it all,” notes McElroy. “Our Telebelts can convey up to 4" (100mm) aggregates.”
McElroy also says Alexander Wagner uses their Telebelts on a wide range of applications including:
•Tilt-up and outdoor slabs
•Foundations and footings
“What Putzmeister Telebelts are capable of is just incredible,” concludes McElroy. “I would recommend them to anyone who either wants to expand their placing business or has challenging, high volume civil projects to handle.”
In addition to their TB 110 and TB 130, Alexander Wagner also owns Putzmeister truck-mounted boom pumps ranging from a 24Z-to a 55-Meter, Thom-Katt® trailer pumps including a TK 25 through TK 70 and BSA trailer pumps including a BSA 1409 and BSA 14000 HP-D.
