When contractor and owner Gus Antoniou, G&D Excavating, Lyons, Ill., needed a creative way to place concrete in a confined space, he turned to a concrete pump attachment for his skidsteer loader. Working on a 50-cubic-yard concrete floor on the second story of a Chicago warehouse, the jobsite's size limitations posed a major problem. “A concrete pumper is a large six-wheel truck, and it wouldn't fit in this building,” Antoniou says. That's when Atlas Bobcat offered a solution.
The attachment pumped 12 to 15 cubic yards of concrete an hour—a manageable amount of material—to the crew waiting on the second floor.
Working with his local dealership, Antoniou connected his Bobcat S300 skidsteer loader to a concrete pump attachment and positioned it inside the building with room for the concrete mixers to deliver the material directly into the pump. Powered by the skidsteer loader's hydraulic system, concrete could then be pumped 12 to 15 cubic yards an hour and up to 25 cubic yards with a high-flow auxiliary hydraulic system.
With his crew waiting on the second floor, Antoniou controlled the pump with the integrated remote attachment control, enabling him to monitor the job's process and flow of concrete. “You wouldn't believe how well the concrete pump attachment works,” he says. “[It] gives the laborers and finishers the right amount of time to place the material. They don't get overburdened with material like they would if it was coming from a concrete pumper.”
Antoniou notes that while a concrete pumper might be the fastest way to deliver material, sometimes it simply won't work for certain jobs. A concrete pumper also can charge anywhere from $600 to $1500 a day—a pricey investment compared to the loader/attachment option where crews can set their own schedules instead of waiting for the concrete pumper to arrive. The remote feature of the concrete pump attachment also saved Antoniou the cost of a second operator and equipped him with an emergency stop button.
Depending on hose length and diameter, slump, additives, and aggregate size and type, the attachment can pump concrete as far as 250 feet horizontally or two stories vertically. The concrete pump attachment also is available with a delivery starter kit that includes three 25-foot sections of 3-inch flexible hose; three 10-foot sections of 3-inch steel line; one 6-foot section of 3-inch flexible hose; reducers, elbows, couplers, and a clean out ball.
After the floor had been poured, Antoniou says the concrete pump attachment can be cleaned while the loader accomplishes other tasks on the job, such as moving pallets of building material or cleaning the site with a sweeper. In the case of a concrete pumper, the equipment would sit idle after it had finished its job, taking up valuable space. The attachment and loader can be transported on a trailer without a semitrailer or commercial driver's license, and workers can do away with wheelbarrows and shovels.
Because the pump performed so well, Antoniou met his deadlines and after three jobs, the pump attachment paid for itself. “You can't put a value on being able to service your customers,” he says.
