Self-dumping Crane Bins Keep Workers Safe

Construction companies gain productivity and a safer working environment with new self-dumping bins distributed by Cherokee Erecting, Hampton, Ga. The new contractor-designed product comes in 1-, 2, 3- and 4-yard models.

The new Cherokee design offers a sloped side for ease of loading and offers hands-off dumping after the loaded bin is attached to the crane. Once the loaded self-dumping bin is lowered into a construction site dumpster, the crane operator cables down allowing the lifting arm to lay back. When the arm reaches the back of the bin, there is a dog bone that swivels to lock the arm in place. The crane operator can then cable up to dump the debris. The bin is then carried away in the vertical position to the next location. When it's lowered to the ground, the slope on the front automatically lays it into the correct position. Then construction personnel can remove it from the hoisting mechanism.

The new product is designed to keep workers out of trash bins when they remove rigging from a crane used to hoist a cleanup bin. With broken glass, lumber, nails and other jobsite debris in dumpsters, keeping workers out of this dangerous environment should be a top priority for construction companies, according to Cherokee Erecting. Plus, the 6- to 8-foot sides of most roll-off dumpsters are too high for workers to jump from without risking ankle injuries, especially in wet or icy conditions.

The conventional garbage bins were tested against the new self-dumping type on a recent high-rise project in Atlanta, Ga. The old bins took two men to attach the rigging and one man to climb into the dumpster to remove the rigging. From the time the old-style bin was attached to the tower crane, dumped, and then released, the total crane time was nine minutes. The self-dumping units took one man to attach the rigging, and one man to remove the rigging, in a total of two minutes according to Cherokee. This amounted to a total of 27 minutes of crane time saved on this particular project.
