The problem with supporting a truss, like on these cranes, in that manner is that you are introducing one hell of a point load at that point on the truss. That's right where it will bend, or break. You have actually weakened that truss by not allowing the entire structure to "work" and properly distribute the load down its length.
Thanks, javadog, for the great explanation of these kinds of cranes. It sounds like you have worked with them a good deal. Like I alluded to earlier, us airplane guys are far from being crane guys. We rely entirely on guys like you, with your expertise, to supply the cranes and set them up. We trust whatever you give us.
