Lifting Hook DIN 15401

grabcad

The part Kranhaken_DIN15401.SLDPRT is a lifting hook according to the german standard DIN 15401, type RSN, in the sizes 04 up to 40. The model is precise in all dimensions given by the standard, i.e. the standardised cross sections are correct, but the not-defined spline transitions are just smoothed. This type of hook is the worst-case in regard to design space. Of-the-shelf available hooks usually are slimer and have a larger opening. The native SolidWorks part features 17 configurations, each for every size. It was an exercise to model a spline based body driven by a design table. Unfortunately SWK is quite buggy in this respect, so that sometimes switching from one coniguration to another the model gets errors. If you switch via another configuration in-between the errors don´t happen. To avoid hassle, I exported every size as an individual STEP file.
