This is a 6x6 1/15th or so scale Airport Fire truck with working water lines and full suspension.
About this creation
A little while ago The Lego Company put out their 8 x 8 airport fire truck set 8454. My plan was to make mine look much better. This is a 1/15, or so, scale model of the E-One Titan 6 x 6 Airport Rescue Fire Fighting (ARFF) with a Snozzle boom. This is the first “large” model I have made and it became a much greater project then I had planned. It, at times, made me angry that things would not work but it also made me re-look the project and try, at times many times, new ideas. I have researched the Internet for large Lego scale items and there are a LOT of them out there that look incredible, with such detail that I cannot begin to talk about mine. Inside, this truck there is monster space to put everything in so this was the one worry I did not have.
This Lego model has working suspension, not quite like the real one mainly due to the weight of the model. I broke a few pieces along the way so I changed the axels to hold more weight. It has front wheel steering and an inline 6 cylinder-working engine. The engine in these types of trucks is inside the rear sliding cover.
Knobs on the left side of the truck control a motorized air pump. It runs four pneumatic rams to lift the Snozzle boom. Since the boom is so large, the Lego rams were to “pull” the boom up but they did not have the strength so I had to make some modifications to make this boom “push” up. Again, these rams are operated from two switches at the left side of the truck. The boom is motorized so it can turn. The boom is geared to make it turn very slowly. The boom can also be extended about 12 inches or so to get a better reach to the fire. The end of the boom has a working water nozzle and a mock-up stinger used to puncture the side of an aircraft skin in case the fire has spread inside. The extra hose can be rolled onto the spool on the side of the boom.
The truck has two functioning water lines. One runs to the top boom and one to the nozzle on the front of the truck. The front nozzle can be turned left, right by a knob on the right side of the truck and it can be moved up and down by hand. There are two water in ports on the right side of the truck. The first plan was to have a water tank and pump on board, but due to the ever-increasing weight, I decided to hook up to an electric windsheild washer pump that pumps the water through the truck. There is also a hose real in one compartment that can be open and closed.
An 8x8 RC truck is built and I will try to post some picures and info of this truck in the next few days.
