Hi,
I've finally gotten around to take a few pics of the work I've done so far on the HIAB crane mod for the 8110. I've uploaded them to my
brickshelf gallery, and included some information.
I wanted to make a three section telescopic crane that was as compact as possible to resemble the real HIAB cranes used on many mogs. I managed to make the main structure 4 x 4 studs, with some bracing increasing it to 4 x 5 studs. The only thing i don't like is that the pneumatic cylinders look so bulky... We NEED a new longer cylinder that has a smaller diameter!
To make the telescopic function extend 14 studs (24 to 38 total length) I used a chain with two belt pieces to lock it to the first and third part of the boom. The second part has a set of gears to run along. I chose this rather than using thread, like in the 8421 Mobile Crane, both because it would be harder to fit, and because it would make it more mechanically satisfying to me. It was also a good trial run for a forklift I'm planning on building.
For the extender function it was never an option to use a gear system, as I want to keep it as close to a real HIAB crane as possible. I just wish TLG would come up with a longer more sleek looking pneumatic cylinder. Let's hope pneumatic is back for good and that TLG will make more cylinders and a return to center RC valve.
If you look at the pics from LDD in my gallery you will see where i connected the belt parts marked with pink axles.
And the original:

More is still to come.

EDIT: I've re-sized the pictures, enabled deep links, and uploaded a couple more to my Brickshelf gallery as well as the .lxf file from LDD. You are all welcome to use it.
