Manitowoc Cranes

admin

I live a couple blocks from The Manitowoc Crane company. I drive past there everyday on my way to work. I have not been around cranes too much in my life and am amazed at the size of some of these things. I bet the weld inspection is brutal in the factory.I wonder what type of machine they use to cope that huge pipe or tube that they use? Laser? Plasma?
Reply:I would think as many crane booms as they build, it would all be CNC cut / machined. Here is one of their customers.  http://www.lampsoncrane.com/Projects.htmlDon’t pay any attention to meI’m just a hobbyist!CarlDynasty 300V350-Pro w/pulseSG Spool gun1937 IdealArc-300PowerArc 200ST3 SA-200sVantage 400

Reply:CEP, did you mean to say "competitor"? Lampson has long been the largest mobile crane manufacturer in the world, they are built in Pasco, WA. There are plenty of cranes with greater capacity than a Lampson, the difference is in their mobility. When I toured their facilities a number of years ago the largest model that they had at the time would lift 2000 tons with 400 feet of boom. One of their sales brochures at that time showed a Lampson crane lifting the largest Manitowoc built as a sales pitch. They had that picture in their sales booth at one of the national trade shows that same year.........right next to Manitowoc. Best regards, AllanEDIT: in almost every case where there has been a failure of a large crane, either geodesic information wasn't properly considered, wind speeds were ignored, or other errors on the part of operators or engineers were the root cause of the failures. Lampson, Leiberr, Manitowoc, and any other crane manufacturers have had similar failures due to these reasons.Last edited by aevald; 02-22-2011 at 07:59 PM.aevald
Reply:Allan I did not know that Lampson built cranes! I thought they rented cranes, and were a rigging contractor. I've been on jobs with their cranes, and they were Manitowocs.Don’t pay any attention to meI’m just a hobbyist!CarlDynasty 300V350-Pro w/pulseSG Spool gun1937 IdealArc-300PowerArc 200ST3 SA-200sVantage 400

Reply:I used to run a crane for north shore.  Small mobile crane called a garland dinasour and super goliath.  Mine was electric over hydraulic with a rotec (rotex?) base all of the function brakes electrified too.  It was a real pleasure to run that machine.  Strong too.  Nothing puts you (me) in the zone like jumping behind that control panel and going to work.  It was like a contest in my head...  Shoot out the stick rotate and drop the line down so close to the pick that a rigger didnt even have to touch it.  Sweet job.  Working with those guys was the time of my life.  You guys ever have a job like that?  It didnt pay as well as automotive but the things I learned and the people I met were priceless.
Reply:The biggest Ive been around is a 4700 drag line. I think thats a Manitowoc. I a drag line still considered a crain, just used in a differant apaclation.
Reply:Are you in Manitowoc, Wisconsin?Isn't that where they once built submarines for the U.S. Navy?
Reply:Hello CEP, Lampson got his start on the Hanford Nuclear Reservation west of Richland, WA. He was somehow tied into the construction of the containment buildings. They would generally build the circular containment walls and be installing the guts at the same time, yet when it came time to install the dome all of the work inside would have to be halted while the dome was constructed overhead. He noted that if there was a way to construct the dome on the ground and then lift it in place after it had been constructed that there would be a very limited time when work inside would have to be delayed. That is apparently when he started Lampson Crane. So, they would pour a pad near to the containment building, construct the dome, and then set it in place with one of Lampson's Transilifts. The Transilifts that were being built at the time that I was there utilized 8 Detroit diesels to make the tracks move on the two mobile track carriers, each individual pad for the tracks weighed roughly 1500# apiece, there were two additional Detroit diesels that operated the winches, and the cable that was used to string the boom and block measured 16 miles in length(this was with a 400 foot boom). The boom sections were 11 foot square and built from A514 grade steel(T-1). They originally started out with large concrete blocks for the counterweights and then later switched to steel boxes that could be assembled and disassembled. They would rent rock/gravel from a local quarry and then return it when the job was done.      I haven't followed Lampson or Manitowoc for quite some time now, maybe they have merged or otherwise come to operate together in some capacity. Regardless, big cranes and big lifts are certainly impressive and interesting. Best regards, Allanaevald

Reply:That's a Vicon.  Manitowoc originally designed the first Vicon heavy lift for the I 480 Bridge over the Cuyahoga Valley, south of Cleveland, Ohio.Nice units, nice sticks.
Reply:We had a bunch of 777 Manitowoc's on a job, they made the old Link Belt truck cranes look small. We could pick up the world with those  Manitowoc's.Disclaimer; "I am just an a$$hole welder, don't take it personally ."

Reply:Originally Posted by barefooter14They are getting a contract for building 10 navy ships right now. and yes they built U.S Navy submarines here. everything in industry seems to come from wisconsin. cranes,miller, navy ships, Oshkosh corp building military trucks, they also own pierce and other truck companies just to name a few in my area, the list goes on!oh and bailiegh is to from what i just learned?? I think I should go up to manitowoc and tour some places maybe even try to work up there soon.
Reply:The weld inspection on those isn't anywhere near as rigorous as you'd believe.  We ended up having to do some NDE to our cranes on site.  A call from Manitowoc asked us to check certain spots after reported issues - all failed UT.

Reply:Ive been on a job where a potain tower crane sheared a pin in one of the tower sections. Near total catastrophe. Evacuated the building and had the ironworkers there all night gusseting up the failed section. Apparently a bunch of pins were bad because they shut the crane down permanently.

Reply:Saw a lattice boom collapse in miami when I was working on a nearby building on a scaffold.  one of the pins popped.  sounded like a howitzer.  then another then another.  on and on till it came down.  it shook the whole building including the scaffold I was standing on.
