Slab Removal Projects
Kenco’s Slab Crab makes quick work of bridge deck removal and demolition of concrete slab projects.
Models are available for 20,000- to 150,000-lb. excavators. The Slab Crab is also available in models to fit backhoes and skid steers. It comes in widths of 24 to 60 in. and processes slabs from 4 to 20 in. thick.
“The Slab Crab is designed to effectively remove concrete with a purpose-built open-sided bucket,” says Tracy Black, Kenco. Slabs slide into the bucket. When it is tilted back, the slabs are held into place for safe movement. A flat-bottom design allows the operator to avoid disturbing the sub-base.
Black notes, “The Slab Crab is ideal for bridge decks. Contractors typically precut their slabs down the beam centers. Once completed, the operator can drive the Slab Crab-equipped excavator over the bridge deck to start the removal process. Using the Slab Crab for bridge deck removal greatly reduces the amount of debris. Due to the design of the bucket, slabs can be stacked or loaded with little effort.”
Many contractors report successful results using the Slab Crab. For instance, Oakgrove Construction Inc. is a general contractor specializing in heavy/highway construction with an emphasis on bridge replacement and reconstruction. Its base of operations includes the eight counties that comprise western New York. “The Slab Crab is safer and much less labor intensive than other methods of removing slabs,” says Bob Spengler. “Debris isn’t much of a factor, because the slabs can be removed intact.”
Perrett Construction, Valentine, NE, also benefits from removing slabs intact. “We use the Slab Crab three to four times a year removing bridge decks,” says Greg Perrett. “Many bridge removals are made over water or wetlands that can’t have concrete dropped in them. We saw the decks and removed the concrete with the Slab Crab Bucket. Most of the time, we are able to give the slabs to a landowner. Previously, we demolished decks with a wrecking ball, cut the rebar with torches, hauled the rebar off to a scrap yard and then had concrete to dispose of. The Slab Crab greatly reduces labor and disposal costs.”
Then there are the time savings. “At times, we use it every day,” says Ernie Troiano Jr., E. Troiano & Sons, Wildwood, NJ. “It works great on sidewalks and driveways. Removing bridge decks is now a one-man job compared to a two- to three-man job.”
G. Marchi & Son, Columbus, OH, cites dependability via a simple design. “Our Slab Crabs are used every day,” says Mark A. Marchi. One reason is their construction. There are no bearings, nuts, bolts, screws or grease fittings – zero maintenance. “After removing over 100,000 sq. ft. of concrete, only the paint is scratched. We use the attachments mainly to remove sidewalk for wheelchair ramp construction.”
