ACPA offers several alternatives to this setup, including changing the boom configuration to minimize vertical drop, using reducers in the hose, and placing the S-elbow at the end of the boom and using a rubber hose below to move the weight of the elbow away from workers.Henan Daswell Machinery Co., Ltd,is a professional manufacturer and trader specializing in the research, development and production of construction machinery for nearly 30 years. Our main products are as follows:diesel engine concrete mixer,diesel concrete mixer,etc. We will provide you with the best product and service. But in this case, the issue is not as clear as it might seem, since both the Chicago Department of Transportation and the Illinois Department of Transportation require the use of an S-elbow. Joan Anderson, owner of Anderson Concrete Pumping, South Holland, Ill., the project’s pumping contractor, offers no apology. “We were required by all of the inspectors from the City of Chicago to use this on the pump hose hollow block machine,” she says. “I went to many meetings with them and took all of the documents from ACPA and showed them the reducers but they wouldn’t listen. I wouldn’t use this setup if it wasn’t required, but I want the work, so I have to do it this way.” Anyone who’s spent much time on construction sites has seen unsafe practices used either intentionally or through ignorance—maybe even the ignorance of the customer. And most of us have complained about overzealous safety inspectors. But CC’s position is to always show and describe safe practices and to never take safety lightly. Sometimes, though, we fall into the ignorance trap and show something that is not safe. When that happens, as it did with our January cover, we will be the first to point out the mistake and will take every opportunity to explain the issue.
