Different versions of a sharp edge

Edge radius
If the edge radius "r" is smaller than the thickness of the flat sling/round sling "d" , the edge is considered "sharp". Lateral movements or surface pressure can already be enough to sever the lifting gear.

Edge angle
In addition to loads with rectangular edges, there are goods with deviating shapes. These include loads with protruding edges and with sharp or jagged outer contours, such as cogwheels, turbine blades etc. These edges cannot be determined by the general rule.

Edge shape
The shape and surface finish of the edges have a significant impact on the durability of the lifting gear. Very rough surfaces, such as those of a prefabricated concrete component, can very quickly damage textile lifting gear or a wire rope.
Tools for measuring radii
In order to assess the sharp edge, „tools“ are required.
The following tools can be used to determine radii:
- Radius gauge [a]
- Vernier caliper [b]
- Folding ruler
