Re: TCI\'s Effer 655 Knuckle Boom
A huge advantage of having down and outs instead of a-frame outriggers. BUT, according to my crane inspecter anyway, OSHA says that if you are short jacked on one side (and you better have factory load charts for the various amount of outrigger extention) you must go by the chart for that extention. So....even though they are out all the way on the side you are working, if the other side is in, you must go by the chart for the in side.
Make sense? Of course not! But that is what they say so good to know if you intend to fully comply, common sense aside.
