Round sling / span set 圓形吊帶
A continuous loop of load-bearing yarn inside a protective sleeve, used to wrap a beam or a truss and take a hoist. Colour codes the capacity in most European ranges, though the colour convention is not universal, so read the label rather than the colour.
中文
保護套內為連續承力紗束的環形吊帶，用來繞過鋼樑或桁架承接葫蘆。歐系產品多以顏色標示載重，但顏色慣例並非全球一致，應以標籤為準而非顏色。
