Felonyass:

I don't have one of my own to show you- but I know my local welding store sells three different models. I went to their website and found pictures of them. I've attached the links to them too, but their website is pretty scant on details.

If you'd like me to go there and take some better photos, or make any measurements for you- let me know and I'd be happy to.

Exactly what you are looking for:

I have the first crane that aquafire posted a picture of. The manufacturer's installation was to use 4 1/2" bolts through the bed, and through 2 pieces of 1.5" angle iron that are slightly longer than the crane's base is wide.

Your crane looks to have a smaller base plate than mine, and mine is rated for only 1000 lbs. I'd install a thicker, larger plate under the bed to help distribute the load from the crane to a larger area. If you go the route of Combat Jump's crane, then a jack stand under the crane base will help carry the load away from the truck bed.

It's worth mentioning that your crane has a longer extension boom, and a higher load rating, with a smaller base plate, than my crane. Something doesn't add up here, and I'd be very cautious using that crane until you fully comprehend what its' limits are. The max lift capacity for my crane is only reached with the boom in it's shortest configuration. Lengthening the boom dramaticly lowers the lifting capacity. I didn't see any markings on the boom for your crane, but I'd be willing to bet that the lifting capacity at full extension is only 100 or 200 lbs.

I suspect you know this already, but I though it worth mentioning for others who may read this topic...

Should it be attached to the frame or bolted/welded to bed .

a dab will do said" a higher load rating, with a smaller base plate, than my crane."

thats what i was wondering about ,i have a 12 inch square piece of 1/2 inch i willl weld the base to,does the manufacturer say to mount it to the bed or the frame?.

the max i can see me lifting would be the titan at 650 lbs

Oops- I just re-read the original post and realized I missed the boat slightly on what you were looking for. (It was the first post I read when I woke up this morning- next time I'll WAKE UP a bit more and have a cup of coffee before I start typing).

 

So sorry Bud...

I had read through CombatJump's thread as he developed his idea, and I thought that his explantion of how HE did it would maybe help you decide on how you wanted to do yours...

Highlights:

1) Mounted in the Passenger Rear corner of the bed so that loads can be lifted from behind the tailgate, into the truckbox.

2) Used an oversized sandwich plate bolted through the box floor, with nuts welded to the underside for easy removal when crane is not required.

3) Bottom of sandwich plate is attached to 2 pieces of channel, and then welded to the truck frame.

4) Fabbed up custom slide out, and swing down outriggers to stabilize while loading.

What did I MISS?

Now.... In direct response to your question - I am considering building something like this for my own use, and while I am not so sure about "Welding it to the truck frame" as Combat Jump described in his first post, I would definitely consider attaching the channels to a plate that is BOLTED to the side of the frame....As of right now, there isn't a whole lot I would change with the overall idea - I would also bolt through the bed, and then tie the bottom sandwich plate to the truck frame - Hate to sound like I am Rubber-Stamping someone else's ideas, or passing them off as my own, but It just makes sense to me...

Most of my experience is with Class 8 trucks, and the pickers are much MUCH bigger, but the principles are still the same.

Have a Good Night Eh!

 

Mine is better, Full hydraulic

I made a new plate 1 inch thick and ran 2 x2 x.250 tubing to the frame

 

i have been planning on something similar but instead of mounting it to the bed i am going to use the reciever hitch and along the bumper to the corner of the bed. the corner will have a hand cranked baseplate for stability and a cherry picker style crane on a swivel base, that way it is completely removable.

 

I just gotta give scooter 383 an atta boy a auty looking crane

 

Good advice all, just to add Princess Auto used to sell similar pickup truck cranes and a pedestal for mounting them. Might be worth a look to see if they still sell them.

 

Are you sure that crane will hold 1500lbs? This one is my truck bed trailer, used for ELK hunting, had to put jack supports aslo. I also have one that slides into the receiver, i will have to pull it out for thr pics.

 

i know this is an old post but do you have any photos on how you mounted to the frame i also dont want to weld to the frame i want to bolt it on thanks
