I think shovels and draglines use the same method. A series of clamps on each side of the drums. Look on threads on this forum and find interior views of draglines and look for close ups of the drums with the cables attached. I have seen them but do not remember which thread. I don't remember seeing any close up shots of shovels. Are you building a scale model? Also look at "stripmine.org". Lots of pics of draglines but you will have to do a lot of searching or maybe google interior pics of shovels and draglines. Good luck
