I work in the rigging and lifting industry, and have may dynamic blocks for single leg slings, but nothing for 3 part or 9 part braided slings (i.e. Gator-Laid, Tri-flex, etc.) Anyone have any blocks they use or know where to find them?I have tried to manipulate the blocks I have for the correct dimensions and have burned out my brain at the moment.

Hello a.wickander, I think I have some block blocks in my LIEBHERR files here in the site, but not dynamic.Eventually see : LIEBHERR_LTM1090-2_3D.dwg and LIEBHERR_1300-6.1_3D.dwg.You could also ask directly at LIEBHERR because they give their AutoCAD files.The files that I had from them including the ones that I made with those files like : LIEBHERR_LTM11200-9.1.dwg ( the bigest mobile crane from LIEBHERR ) are coming I think from 3D and the very first thing that you would have to do is an OVERKILL to erase the duplicated entities.You could also ask directly for blocks files. Some other crane builders are giving their AutoCAD files like TADANO and/or others maybe.

Are they crane blocks or sling blocks?  I have the crane blocks I am just looking for the slings

No they are crane blocks.On the other hand if you are looking for rigging components I have done a lot of them uploaded in the CAD/BIM Blocks library.STEEL_WIRE_ROPES_3D.dwg ( 2D and 3D slings )2130_SHACKLES_BOLT+COTTER_PIN;dwg209 SCREW PIN ANCHOR SHACKLES.dwgWith a search with the name : CROSBY or DIN_15401 or DIN_15-402 you can find things.I have also some 3D files :DERRICK_25_t.dwg , TIRFOR_TU32H_3D_CROCHET;dwg , CROCHET_1_6T_3D.dwgI have also other CROSBY components not here in the site.I'm working in a "site methods" office dealing with road transport, erection on site, cranes, winches, slings, rigging components, etc...
