Tilting and setting with cranes that have a luffer.

| Devin Parsons posted So this happened today my buddy JD had do do some demo clean up... This trip 9 was only on the job site a few days. Operator is alright suffered a broken ankle from when he bailed out and ran. |

| Tony Snoke commented on the above posting Eric S Manners What happened |
Scottie Thompson From what I've heard he was walking high sticked with a precast panel.
I gather that "high stick" means the boom was too vertical so that the panel was dangling too close to the boom.
Some comments speculated that the boom was not properly inspected. But someone said that, since it was an "All" crane, the boom segments would have been inspected as they arrived on the truck and then the whole boom would be inspected again after assembly before the boom is raised. This time they can skip the inspection at the end of the job for any damage.
Jerry Spearn Walking high boom there is a good chance the piece made contact with the boom. There is a video some place of a boom test being done . At 85% capacity they hit the main cord with a ball peen hammer and the boom exploded. I'll see if I can find the video.
Ben Stalvey So glad the operator is okay that 999 can be replaced they are a dime a dozen really.
Ben Stalvey Aaron Nelson I am sure can tell you all about hauling precast and how dangerous it can be. His company hauls alot precast and are around cranes that lift precast alot. It takes alot skill from the driver and crane operators really. On even just delivery and then the flip of them on a jobsite.
Aaron Nelson And is exactly why I won't allow my drivers to bring their kids with them, this stuff is way to unpredictable and I don't want that on my conscience. Job we're on now has 80k wall panel and 90k beams.
Ben Stalvey Very true several cranes have went down in time during tilt wall precast work.
Louie Dee See a lot of these companies using hydro crawlers for precast.
Ben Stalvey Around here locally I see that also. Less setup time less risk to then running a crawler crane

| Chris Ludlow posted Triple 8 setting rock, 50T Grove truck mount hanging iron on the stair tower, and an 860 JLG just because. Chris Ludlow It was tight quarters for sure! They needed us to get the stair tower erected so they could set the precast stairs right after to finish the garage and tear down the 888 right after. I'd worked with the 888 operator before and he's pretty smooth, set that panel right in there with out a problem. [Lots of comments about this being a safety rule violation because people are working inside the "fall radius." If they did not violate the rule, they would have had to pay rental for 4-5 days for an expensive crane to set idle. while the steel for the stairwell was erected.] |

| LR Willson & Sons Inc posted Aerial perspective of LRW crews erecting a Data Center in Northern Virginia earlier this year. These 62' tall tilt up panels weighed up to 170,000#. We utilized a Manitowoc 16000 440 ton crawler crane. |

NessCampbell Cranes 2250 and Sierra Construction Company INC erecting tilt walls in Tacoma, Wa. My first experience tilting with a crawler from the outside. I'm sold! 3.5 days 101 panels up 71 to go! Nice job by all!Josiah Shirley Makes it so much easier!!!
Jamey Clark I agree. Moving a hydraulic or lattice boom on rubber around the outside is a lot of effort. Each move you have to drop bar, if hydraulic crane they suck the boom all the way in prior to rolling. Takes to much time. I would choose this crane every time if the mobe cost wasn't a 75% increase over a rubber tire rig.
Jamey Clark Very versatile rig, but expensive!
David Beard Have hung many precast panels. A good job with the right crew. Enjoy it myself.

Broc Sherwood posted two photos with the comment: "Nice crane these boys are using...the owner takes good care off it...Slinging some Pre-Cast."
They must unload the trucks onto the slab with a smaller (e.g. cheaper) crane so that when they bring in the big crane to tilt them up they don't have to waste the crane's time waiting for trucks or the truck's time waiting for the crane.

Wow a ot boom for tilt wall work.Wayne Mansfield They need it for the last few trusses and wall sections. They have a goofy setup at the end. We need the reach.Mike WeaverMike and 4 others manage the membership, moderators, settings, and posts for Manitowoc Crane Enthusiasts. Great thing about that #22 boom. Length doesn’t change chart a lot...but you better be level... |

| Patrick Ng shared Virginia-based crane rental outfit, W.O. Grubb, has reported that Manitowoc's MLC300 crawler is quickly gaining recognition among customers as the best crane in its class. W.O. Grubb CFO Michelle Grubb-Solaimani said that the MLC300 is helping customers to save time and money on job sites for many kinds of work, and is now the most requested model in its 80-plus crawler crane fleet. She said: "While performing tilt-up work, it’s very common to relocate a crane several times. By equipping the MLC300 with its VPC-MAX attachment, the crane travels easier on the job site and doesn’t have to be repeatedly re-set up for lifts. We used to have to use cranes with counterweight wagons for these jobs, but the MLC300 can handle the work without the additional costs of transporting a wagon and all the matting work that goes with it." W.O. Grubb's MLC300 units are already booked well into 2019. Brian Showalter Ben Stalvey first tilt wall ever.Charlie Ward my only fear is one day an entire building will be built on it's side, loaded on a barge and Manitowoc will build a rig large enough to "trip" it and set it in place. |
Dion Paparone posted two photos (below) with the comment: "Our 2250 on tilt-up....."
Some of the comments talked about the "suicide position." Finally someone asked and the answer I understood is that the top is on the crane's side of the bottom and the crane is closer to the bottom than the wall is tall. So if something breaks, the load will fall on the crane. One comment indicated he would be one panel to the side so that it would fall next to his crane rather than on it if something breaks. For example, "when lugs pull out."

Love a 14000. Quick and smooth rigs.[These are skinny so that they can be hauled on a truck.]

Quite a few comments on various posting have commented about how dangerous tilting wall can be.
 |
| Joe Hinson commented on the above posting It's was a tilt up job the trip 9 was out of the Raleigh office on bare rent he was trying to back up a hill with a 140 thousand pound panel and the hill was about 5 degrees off to the right too. |

| Charles Hall posted [We have already seen this picture. But some of the comments provide some insight.] Keith Gregory Who is in charge of securing these dam walls? Devin Parsons Wasn't the wall securement the crane was off by 5 degrees to the right and with that much stick it sent the boom over. Devin Parsons Crane off level 5 degrees sent the boom crashing down panel was 140k. Joe Whiting Saw this last week it said he was traveling up hill off the side with the wall...I thought well that may do it. |

| Thomas Dearmond posted The dangers of tiltwall, and for the record this wasn't one of my jobs. Greg Vandeventer Tilts have been and will be the most dangerous thing to be done with a crane. [The comments indicated this happened while the panel was being walked into place and the boom was "side loaded." I surmise the crane tilted. There is no discussion of what kind of ground preparation and/or matting was done. One comment implied a Manitowoc 999 was not big enough for the job.] |

| Screenshot @ -0:12 [Note that the guy in the yellow shirt that was standing on the panel got flipped off when something broke. Then someone starts running along the path of where the boom is going to fall before he finally decides he should be running perpendicular to where the boom is going to fall. It reminds me of the people that run away from a falling tree along the path of where the tree is going to land. I can't decide if directors have them do that for dramatic affect, or if people really do that in real life. I guess this shows that people really do that in real life.] |

| Seth Shern posted Ben Stalvey  888 good for 230 ton. Popular one for precast like 2250s, 999, 14000.[There are some comments about standing a panel up on a trailer. This panel has a foam core and weights 26000#. "Ben Ballard that was also the largest ones we stand that way. The larger ones and panels with large openings were tripped with two lines." Another comment wondered why they didn't just pour the walls. I've seen a lot of warehouses built lately along I-55 and I-57 and they are all precast tilt wall. Pouring would be more labor intensive on sight. And cold weather becomes an issue.] |
(new window) "Bad day lifting 50 Ton panels in Napa!" (source) It starts falling over at 0:18.
They used to precast and lift entire hotel rooms, not just columns, beams, slabs, and walls.

| Joseph Collins posted (video in case you don't have a Facebook account) Check out the 10 degree offset boom top on the 4000 ringer. The spreader bar was made from a helicopter tail roter and was used to rotate the hotels rooms. Man, things were a lot more fun then!!! [The video shows the crane in operation.] |
A video of building a wall with precast segments between already constructed columns. This looks safer than tilting.
A video of standing wall panels. (source) I wish he had spent some of the dead time panning up to the top of the boom so that we could see how the different lines were spaced at the top. Note the bracing on the truck trailer so that they can be shipped diagonally to take advantage of the vertical clearance and avoid a horizontal oversize load. When the built parking garages where I worked, they shipped the floor spans on a diagonal until a union forced them to ship horizontally and pay extra.
A 0:34 video of the crane falling over while a lot of workers were at the base of the panel.
Earl Ray shared KXAN News' video (better video quality, source, Jack Combs A lifting eye malfunction.) of an anchor on the slab popping out and the crane falling.
Marty Bingham He wasn't directly over the load. Looks like he dragged it 20' or so. It also looks like it was side loaded with the house lock on. All that probably put uneven distribution on the lifting connections which overloaded the ones that failed..
George Lamoro Exactly Marty, he tried swinging it to stand up, but still much to heavy, and ripped lug out. I've done Millions of these. You ha ve to weight till straight up, then lift. Guys a cowboy.
Kenny King Guess there are more people how have not set tile ups that i originally assumed. the slide is perfectly normal.
Marty Bingham It’s not normal for it to drift while it’s laying that flat. Plus it’s dragging sideways to some degree.
Kenny King no doubt he wasnt directly plumb, being off the corner like that, it twisted away from the crane like that from being over boomed a bit. also, he may have done that to keep the head out of his direction while standing up.
you can walk them damn near flat like that with a tiny bump of the swing and a dash of boom up or down. doesnt take much.
when standing up on double or triple stacked panels, its good practice to walk the panel in a foot or 2 in order to keep it from jumping off the stack backwards and shocking the crane, only real moronic move was the cowboys riding the panel before it dropped.
