Best knuckle boom for this application

New to cranes but I want to build a rig on a single wheel short wheel base truck . Thinking a 148 in wheelbase International HV single axle 4x4 about a 40k GVWR truck with as as big of a knuckleboom as it can handle . I want the truck to be short so I can maneuver around a yard . Any ideas or input would be appreciated

Your best bet is to start talking with the dealers who sell them. They have programs that can show you what you can do

A few things that will determine the size of the crane you can put on. Rear mount or cab mounting the crane, and if you want payload for anything are 2 big determining factors. I am not sure if you absolutely need 40K GVWR (not sure of your entire plans for the build) but if you don't and go with a GVWR below 33K GVWR then you don't have to pay F.E.T. (12% in federal taxes). And then if you find out you need the payload there is a trick to increase payload and still avoid the F.E.T. I worked out a spec for a Copma 188.6 that would give you about 67' of vertical reach plus a 5' 45 degree manual extension to connect to a grapple saw.
 
Yes I want to know how big (reach mad max lift at full boom) on this truck

What’s the biggest crane you can put on a single axle truck?
If possible you always want the heaviest available frame. If you are buying used I know that isn't always any option. Depends on the axles & suspension ratings, and if you want any payload. Without knowing all the details of a truck probably around a 20 t/m - 25 t/m knuckle boom.
 
Westminster Hydraulics built this truck for me 3 years ago. It is a Palfinger Pk18002 EH on a GMC T7500 Chassis. It has 4 outer boom extensions and 3 fly jib extensions for a total of 70' of boom and ~82' tip height. Palfinger said this was the largest crane they would mount on a single axle truck. I have seen Effer and PM mount 22tm cranes on single axle trucks, but they don't have a fly jib. My truck is a 170" wheelbase, ~25' long. I think the length of that truck is going to limit the crane size you could mount more than the weight of the crane. My truck weighs around 26k lbs. Allmark is right, you need to talk to a crane builder to get specifics.

Correct as when having a jib crane you are going to obviously add more weight to the build with the addition of the jib to a standard knuckle boom. Also yours being rear mount, all of that weight is going on that rear axle as well. Looks like a nice truck by the way. Assume you have a decent turning radius with the cab-over truck.
 
I'd like to know this trick!
It's not a trick in the sense of gaining payload as much as it is of avoiding additional taxes (F.E.T.) on a new truck that is less than 33,000 GVW. If you don't have a brand new truck then it wouldn't make any difference.

That looks awesome. What does it pick at full reach?
 
That looks awesome. You would much rather have this than a 17 ton stick crane with the same reach but a much bigger chart, I’m assuming?

For me it doesn't make sense to own a stick crane. I would have to hire/train someone else to run it while I climb; couldn't set it up in a lot of the places I use my crane; and couldn't use it as a bucket truck like I do my knuckleboom. I like the size of my crane for what I do. I can always rent a stick crane when I need more reach and/or capacity.

Yeah those trucks are insane what they can do
