PierreR89 Posted February 2, 2022 Posted February 2, 2022 This is something that i think i will start building sometime within a month or 2 so there will not be much right now. I have wanted to build this for a few years now and now i finally have all the parts i need for it. I have 2 of the K100 aerodyne kits and decided to keep one stock and turn one in to this. Not much will be out of the box on this build and i also decided to make it look like an Australian truck so there will be many Auslowe parts on it. For the engine i decided to use it the CAT3408 from a W900 kit just beacue i have 2 of them just laying around, one build and one unbuilt. I have not yet decided what crane i want to use on it but i am thinking that the KFS crane will look better then the crane that comes with Italeris accessory kit.
gotnitro? Posted February 3, 2022 Posted February 3, 2022 looking forward to your build. Twin steer trucks are so interesting
PierreR89 Posted May 12, 2022 Author Posted May 12, 2022 I have finally started on this project. I made the frame for it tonight and it turned out like this. 2
'70 Grande Posted May 14, 2022 Posted May 14, 2022 I, too, will be watching this build. I'm curious; what are some of the 1:1 advantages of a twin-steer setup on a big rig? Is it primarily for better weight distribution or does a twin-steer setup also make turning/operations easier?

It is mostly for better weight distribution. Most of the trucks that have large cranes mounted on them have twin frontaxles to spread out the weight of the crane so the axles are not overloaded and still be within the weight specs the manufacturer recomends. Overloading can lead to the axles breaking in half and thats not good drivning down the road. The springs can also break if they are constantly overloaded.
PierreR89 Posted May 23, 2022 Author Posted May 23, 2022 Did some work on it today and it is starting to look like something now. Just a few small things left on the chassie to do before i can start on the cab. 1
PierreR89 Posted May 25, 2022 Author Posted May 25, 2022 After a few hours i finally got the rear cabmounts and aircleaner pipe mounts fitted. The last pic is what i have thought that it should look like but just not with the Italeri crane, it is going to have the KFS Hiab crane just because it is a better size then the Italeri crane. The fifthwheel is a ball race fifthwheel from auslowe. 1
PierreR89 Posted May 27, 2022 Author Posted May 27, 2022 Started to make the aircleaner pipes, there are a few small adjustments i have to make before they look good. Pipe from the aircleaners to the engine is done. I had to modify the kit part to make it fit on the cat v8. Instead of the round airintake that was supplied with the aircleaner set up, i think i am going to use this type of ram tube instead. The fifthwheel is done and works like they should with being able to turn around. 1
PierreR89 Posted May 28, 2022 Author Posted May 28, 2022 Made som small adjustments for the aircleaner set up and made the exhaststacks ready to be mounted when it is time for them. Have to wait to do the exhaust from the engine untill the stacks are mounted to the cab as they will decide were the pipe from the engine will be placed, other then that the aircleaners and exhaust is done. The last part to do on the frame is to figure out where the fendermounts should go over the rear axles then it is ready for paint. Started to build the KFS crane for it today, but did not get very far with it. The base for it is done and roughly where it is going to sit on the truck.
Oldmopars Posted May 29, 2022 Posted May 29, 2022 Please enlighten us (Or at least me) on what the reason for a "Ball Race" 5th wheels is? It looks cool, but it is not something I have ever seen here in the USA. What is its purpose? BTW, great build, it is coming along very nicely.

It looks cool, but it is not something I have ever seen here in the USA. What is its purpose? BTW, great build, it is coming along very nicely. It is to save wear on the kingpin on the trailer and fifthwheel. They are mostly used with heavy haul trailers that rarely gets disconnected from the truck. They have a locking mechanism that locks on to the kingpin so that it can not turn in the fifthwheel like they do in a normal fifthwheel. Instead the fifthwheel and kingpin will stay in the same position and when the truck takes a turn the ballrace turns around instead. When they turn the fifthwheel will stay in the same position as if the truck is drivning in a straight line and the ballrace is doing the turning. Edit: I just remembered that it is not the fifthwheel that locks the trailer so it can not turn. It is the trailers, they have a welded wedge behind the kingpin that fits between the toungs on the fifthwheel locking it in place so the trailer can not turn inside like they usually do. That wedge forces the ballrace to turn when the truck is turning on the road. Some of those trailers have linkages going from that point to each axle if they are steerable and that way the axles can steer in the direction the truck goes. Edited May 30, 2022 by PierreR89 1
gotnitro? Posted June 5, 2022 Posted June 5, 2022 Great progress! Love the exhaust routing, and how the crane is going together
PierreR89 Posted June 7, 2022 Author Posted June 7, 2022 Did some work on it today and got the base done and started on the mast for the crane. I had forgot how to work with photoetch but i figured it out in the end, still alot more to go. Also just realized that i put it on backwards when i took the photos of it.... 1
PierreR89 Posted June 8, 2022 Author Posted June 8, 2022 Got the mast for the crane done, it just need the rams in the cylinders mounted. Started on the main jib and got about halfways with it before i felt like taking a break from it. 1
PierreR89 Posted June 18, 2022 Author Posted June 18, 2022 Got the crane assembled and testfitted to the truck, its big.. maybe to big for this one? Still need to paint and run the hydraulic lines for it.
