Knuckle Boom Crane

Knuckle Boom Crane

Having been exposed to them on the job site, I’ve realized just how handy these accessories are, and I wanted one. You know what they say, the only thing different between men and boys is the size of their feet, and the size of their toys…. I wanted one of these toys!

Click on the links below as I modify a 1951 International L-162 truck to have a IMT 700 Knuckleboom crane onto it.

Link to the manual from IMT for this crane.  It also shows the load chart on page 6 of the PDF.
In looking closer, this is NOT the right manual for this crane.  The load chart is really faded that is riveted onto my crane, but I was able to write down the load chart ratings.


Mine currently only has one hydraulic extension, and so with that extended, it can lift 4500 lbs, at a reach of 15′ 4″.

NOTE: positions 4 & 5 are not applicable on my crane as they don’t exist.  Those numbers do become important if I were to add a manual extension to calculate the capacity.
