3908 Fundamental study on safety of cargo work with webbing sling : part 1 Fundermental characteristics of webbing slings
Details
In Japan, fatal accidents due to crane works occur frequently every year. It is presumed that the main accident cause is "Use of improper tool for cargo work" and "improper choker hitch methods". As for prevention of fall of the cargo, it is thought that the combination of both of "tool for cargo work" and "choker hitch methods" is also important. However, this seems not to be made clear. Thus, one case study, multiple plywood's hoisting with two belt slings, was carried out by an experiment. As a result of this study, the possibility of falling of no unified multiple cargo was presumed when the cargo was hoisted without "protective equipment for prevention of wear of the belt sling".
