Welcome to "Hooked on Cranes!"  We hope you enjoy our site.  This site was made for my son Gabriel.  We call him Gabe for short.  I think that the love of cranes is in our blood.  He likes them too which gives me an excuse to jump right in and show him what I know about cranes.  That isn't much so we'll learn what we can together.  Gabe has a real good imagination so we'll see what we can build with our new....

 

LR -1750 CRAWLER CRANE

There are lots of pictures on this site.  It's a real bad habit of mine but I love pictures.  You know what they say, a picture speaks a thousand words so I guess I have a lot to say.  You can click on any picture on this site and it will open up a slideshow beginning with the picture you click on.  The slideshow has a menu at the bottom of the screen to get you back to the main site.

I have always been intrigued with cranes.  The closest thing I ever got to run that was close to a crane is a digger derrick truck.  These trucks are used to dig and set power poles.  On occasion, I'm lucky enough to get to play with one of those trucks now and again.  All the other construction cranes, I get to drive by and admire their work.  Usually identified by a large boom in the air, they are easy to spot and I've been known to drive out of my way to spy on one or more of them to see what they are UP to.

Cranes are all over in our world.  They are always building things.  Cranes are even used to tear things down too.  This was the first opportunity for me and my son to come close to a very large crane.  It was a Liebherr 1400 and it was a beauty.  The company that the crane belongs to is a very professional outfit called Bragg Crane & Rigging.  They run heavy haul trucks around the country also.  They are a very impressive group of professionals and I'm very proud to have had the opportunity to get to know them.  I especially want to thank Gil, Kenny and Wyatt for letting us ask all the questions we wanted, and bug the heck out of them with their extremely busy work schedule.  They are really down to earth people and true professionals on the job.  They didn't have to do half of what they did with me and my son and for that, I thank them very much.  Gabe and I are true admirers of their work.

 

Now my son and I are forever HOOKED on cranes.  Matter of fact, that's kind of a catchy name isn't it?  With that said, here are our experiences into the world of cranes.  I found a pretty good deal on the internet for a 1:50 scale die cast model crane from diecastdude.com.  It arrived and we've been constructing things with it ever since.  We'll also share some sites with you that we've found interesting.  I hope you enjoy our site and email Gabe - My crane operator/technician!  He loves to hear from you.
 

 

 

Our crane of choice was the Liebherr LR-1750, 750 ton lattice boom crawler crane.  This crane is a very versatile unit that can be setup and used in several different configurations.  It also has the ability to use more ballast.  Ballast gives the crane more counterweight, thus more leverage to lift heavier objects.  If you could not use counterweight, the object would over power the crane and instead of lifting, the crane would pull down on itself.  You can view all of the configurations in the LR-1750 crane manual available on the Liebherr web site:  Here's a direct link to the manual page.  Here's the statement on the link page about the LR-1750:

Liebherr LR-1750 Crawler Crane

Crawler Crane LR 1750

The crawler crane LR 1750 is perfectly suited for applications in power stations, refineries, bridge construction sites and the assembly of wind power plants. The 750-t machine can be universally applied due to its 140 m main boom, 105 m luffing fly-jib, 21 m assembly jib and derrick attachment, as well as 400 t suspended counterweight or ballast trailer. Compact dimensions of the crane components and moderate individual weights allow a highly economic transport of the crane to the building site. The 750 ton crane can also be operated as a "Pedestal Crane" with outrigger supports, featuring a support base of 13 x 13 m. Lifting capacities can thus be increased by up to 370%.

The neat thing about this crane is, it's awesomely huge!  It takes approximately 24 truck loads to deliver it on a site.  Once it's there, a helper crane begins to assist in assembly.  It takes about 2 days to put it all together with an ambitious crew and all the pieces of the crane on site.  You have to remember that one counterweight alone for this crane weighs 12,500 pounds.  I'm no truck driver but I'd guestimate that you could only transport 2 of those on a flatbed trailer at a time.  The crane by itself uses 3 on the front deck, 3 on the back deck and 9 on each rear side tray.  My math says that's 24 weights at 12,500 for a grand total of:  300,000 pounds.  150 tons to be exact!  That's just how much the counterweights alone weigh in at... not to include the additional weight of the crane itself - the superstructure, the winches, the base, the booms, the luffing masts, the jib, the cables, the stiffeners, the tracks, the hook, the motor, the cab, the decks -- Man!  There are lots of parts that make up this crane. 

Also, in my quest to find out more about the Conrad 1:50 scale LR-1750 crawler crane model, I could not find any information on the manual and was quite curious about the assembly.  So, I can say that this is the first site that not only covers the contents of the box, but also includes the manual.  There are lots of sites out there that show you pictures of the crane itself.

Below and on the following pages are a series of assembly pictures of our LR-1750 crawler crane:
