December 4th - Dodge Mounted Crane
Converting the Dodge from a Flying Control truck, back to olive drab was just the first stage of its transformation. Having had something a bit different for so long, I didn't want the Dodge to be completely conventional. I still wanted something that would stand out from other Dodges, a field-mod conversion that might have been seen on an airfield and something that would be useful too.
I've already posted a picture on the previous page about potentially using one of the steel beams from the old garage to make a crane in the back of the Dodge, something like a No.7 set crane seen in GMC trucks. It was going to be a large amount of steel to store if I needed it out of the truck for any reason and I wouldn't be able to start any work until the garage doors were raised. Something lighter, quicker to set up and more easily stored would be a better option.
An idea struck me ( it was a glancing blow and I was quick to recover!! ).
The diagonal braces of the original design were just there to help support the removable beam, but did I really need the beam at all? That and its supporting structure was going to add most of the weight and complexity. It would also take up quite a bit of space in the back of the truck.
If I made the diagonals an A-Frame crane, it would dramatically cut down on the amount of weight, steelwork and welding needed. Instead of the beam carrying the weight, the A-Frame would carry it, braced by a hand operated wire winch. The winch could raise and lower the A-Frame, giving a longer reach or bringing a load to the point where it could be lifted onto the tailgate/bed of the truck. The chain hoist would still be used, mounted on the end of the A-Frame, to give precise and easy control of any lifting, such as removing a Jeep engine.
My Daughter's child seat is currently mounted on a framework on top of the false floor that contained the spare wheel. The false floor would be removed and this framework would be lowered to the truck bed. The frame would then be extended rearwards to form mounting points for the lower pivot of the A-Frame, while a bracket would be added at the front to mount the hand winch on. The two bars of the A-Frame could be quickly removed and stowed for transport.
I already have the chain hoist and the winch should arrive by courier tomorrow. I just need to finalise the steelwork required to make the A-Frame and extend the framing on the floor. For that I need to get some measurements of the existing seat frame structure and to work out how to mount the winch, once I have its size, so I know the required handle clearance from the floor.
