Steel Soldiers now has a few new forums, read more about it at: New Munitions Forums!
Wouldn't that be too much strain on the rigging, since the angle would be really shallow? Considering the relatively short height of the boom I'm trying to think of a good way to rig it up as a spreader bar as close to the crane hook as possible.
Had a lightbulb moment. Instead of welding tabs to the boom jacks/travel legs that would be pinned to the wiffle tree, why not weld in tabs that will just prevent the tubes from moving? Use 2 short chains that wrap around the tube, connected to the wiffle tree pins using those short chains. Then weld on the tabs to the right/left of where the chain is wrapped around the tube.I like the way you think red but you don't have to weld anything to them to make them work just use two cables going up to the hook or whiffletree and two cables hanging down from the loop ends.

Yeah you just need the outriggers for rotation or side liftsAlso saw this picture on the forum, pretty well confirms how underrated these cranes are. That's one of those heavy ammo trailers (12k pounds?) with no outriggers, no supports, and looks like he's pretty close to full extension.

The TM even list the weights you can lift without outriggers so you do not always need them before lifting. Does he have to much in the air maybe I don't know how much that trailer weighs or what he is doing with it. This thread is about wrecker mods not lifting practices so let's get back on track.no you really need them , with that much weight that high,wouldn't take much wind or movement to topple things over. my opinion as a licensed small crane operator,is this is displaying an unsafe act.the one thing about these trucks is that they are stable enough to swing the boom at full extension with out tipping the truck with no weight on them,letting you move and get set up with out monkeying around with the out riggers. you should always deploy out riggers before lifting weight.
I didn't post that picture (not me lifting it) saying it was a good/safe lift, I posted it as an example of how severely under rated these cranes are. Fuzzy mentioned that the trailer weighs 11k, and as seen in the pic the crane is at full extension with no supports or outriggers. Per the plates, that's just shy of 4 times what the crane is rated for at that extension, with no outriggers.no you really need them , with that much weight that high,wouldn't take much wind or movement to topple things over. my opinion as a licensed small crane operator,is this is displaying an unsafe act.the one thing about these trucks is that they are stable enough to swing the boom at full extension with out tipping the truck with no weight on them,letting you move and get set up with out monkeying around with the out riggers. you should always deploy out riggers before lifting weight.
Proper craneing and Wrecker craneing are two distinct animals. When kept in line with the Long axix of the truck you CAN,Safely do things you should not anfd would not attempt with a proper crane. Same applies to commercial rotators,they do jobs every day that should NEVER be attempted with a Crane.no you really need them , with that much weight that high,wouldn't take much wind or movement to topple things over. my opinion as a licensed small crane operator,is this is displaying an unsafe act.the one thing about these trucks is that they are stable enough to swing the boom at full extension with out tipping the truck with no weight on them,letting you move and get set up with out monkeying around with the out riggers. you should always deploy out riggers before lifting weight.
Still there is a reason for ratings, stress acts funny, again just because you can get away doing something does not mean you should do it or that it will not come back and bit you in the a$$ later, doing something because you can not how you should is how equipment gets tore up and people get hurt/killed.Proper craneing and Wrecker craneing are two distinct animals.

OK what everWith Crane work you KNOW exactly what you are lifting..........or you don't lift.......In Towing/Recovery those absolutes don't exist at Odark thirty on the side of the road. You make educated projections based on what intel you can glean. I suspect the individual lifting the trailer knows exactly what he's doing but I could be wrong. I know what I've done with a Vulcan 882 which a Crane guy would say wasn't " Safe"........but it was done within equipment limits by an experienced operator. Two totally different arenas even though there are equipment similarities. I'd love to see the angle/load chart on a 816/936....not saying it doesn't exist but I haven't found one yet. I did find the load chart but no angles. Always nice to hear from the "other" side.
