I know its the Far East ...that's not how a guy would prepare for the potential of bad ground..on luffer to boot .. For those who dont know ..this is in the book under "NO" The wood appears tight on the rear beam(BAD) and theres no wood under the pad (Not Good)....
ahhh, a double jacked ac 500. where do you suppose it will fail?
not so much the failling as it is the shifting of the fulcrum point from the jack to the inside of the beam .. If i had to get up on extra dunnage then yes ..but ..get the sticks out before she was leveled and went to work ..
I here ya LB 1160.They got a big fancy crane and not enough cribbing.
WOW. The language barrier isn't even at fault here because im pretty sure theirs gotta to be a picture in the manual with a big azzed slash through it saying thats NOT a good plan
this has GOT to be a 'set up' pic. Do you think they would put someone in the seat that would pick on that set up?? Hell, the paint on that rig doesn't even look like its dried yet. That would be a nasty scratch to put on it!!
Did you mean fall:beatsme I don't think I would even set a carrydeck crane on a drain.. If they are worried about breaking the sidewalk, then what about several buildings sliced in 2
No ..with the travel in the suspension on that unit ..there's no reason to jack like that get set up .. why would an operator jack a crane around with 120 metric ton of counter weight on? ..he wouldn't ..She would have been set and leveled before bringing the counter weight on board .. if memory serves me correct she can only be walked with 60 metric ton on ..with a maximum of a 140 feet of luffer .. These guys were just trying the "Darwin " way of distributing the outrigger load ..
Often ..and Ive have seen it in the past ..they get focused on the problem and what the fix does is as bad or worse than the initial problem.. and in the event off...the outcome is usually the same .. Realistically.. the whole area under the outrigger's should have been matted out ..any void shore-jacked with beams.... filled with gravel or something ..to fill the void .. Ive set up on parking garage's ,main floor of an art gallery with 6 levels of underground parking .. and she's shore jacked right to the ground floor ... You can set up on a void ..but measure's have to be taken and assessed by a professional structural engineer ...not the sales man ..
One place I worked, the office poeple thought the crane could pick it's weight the entire range... 18 ton meant 18 ton... I showed up at several jobs and there would be a 18 ton Link-Belt setting on-site... Heck it's just barely enough crane to set the small precast panels.. They finally delivered a 35 ton... with it, I could at least set 3 panels before moving instead of one at time... the real hard sell were the ones on the second story, which were set back another 20 feet... They hauled in an American crawler ... to do them and the office the whole time crying we bid it for an 18 ton. Maybe it wasn't cribbed... then someone said ***... hopefully the cribbing was temporary.. so they could fill in the drain with cribbing... But the way it looks .... I'm thinking lift day might be a good day to go to the market.. Or buy insurance for your apartment
LOL..That reminds me of...way back in the 80's, we contracted a job where we had several lifts 100' high. We were looking at leasing a cherry picker (RT). There was a considerable price difference between say a 15 ton and a 30 ton. My dad wanted to get the 15 ton of course. I think it had 105' with the jib folded out. He said, that's enough crane isn't it? To which I replied, YUP, we can balance the load on the tip of the boom and push it up there. NO problem.
My favorite : I got the particulars to do some boats at a yacht club ..the job had been scaled prior ,there were two cone's marking the center pin of both setup's ,with a KMK 6275 Krupp (275t) Got there it was dark and late at night ..set the pin over the cone ..erected and left for the night .. next morning pull in and just go ***! It appears the administrator of the club felt that we were being "to safe" and the crane was "way to large" for a 60,000lb boat..so he shifted the cones back another 75-80 feet ..to get the most production from one setup ....His theory ..it can pick 275T and has 186ft boom .. We protested ..but he knows better than us ..so we went to work wasted his time to show him it cant be done ..then re-scaled the job ..and did it in two setup's .. He didn't use us the next year... but it was rumored that the next guy just pulled his crane out .. the year after they had a crane go over and waited 3 days before calling the Osha group ..at which point they told them everything the operator's past and present had done wrong and that the idustry is riddled with problems ..after interviews with the operator's in the past ..my group included ..the club suffered major fines and that every year a crane consulting firm be called in to assess what crane and where it had to go before they would be allowed to carry on with any major movement ..,, They suffered major member loss because of the rates for the launch and pull out were to much .. Ironicly the other club's in the area took heed and planned and played by the number's to avoid being put in this position .. other peoples children ...man I tell ya!
I'd rather they didn't use me, if they're going to try and force you to do something you KNOW isn't safe, or impossible.
The Crane is owned by Tiong Woon in Singapore cant understand why they needed to put the support under the outriggers, that is why we have so many incidents out this part of the world ...
The spools (for lack of a better word) that they are using look to be older that the crane.Just wondering if that is a bad habit carried over from being around older machines.At any rate that with throw off the capacity and damage the outriggers.These newer hydros will not stand extra blocking like that.I'm betting that if any load was on that blocking there is a ding or dent that will come back to haunt them later
