About this creation
PFTruck is the alternate model of LEGO set 8285 (tow truck), but it is enhanced by including Power Functions. Earlier i did the same with the Mindstorms NXT set, see NXTruck for that. This time with PF, which allows for some further improvements.
To make it more challenging and to make it easier to rebuild if you have the set, I ONLY used the set parts, and added only PF motors, receivers and battery box.
I plan on taking pictures when i take it apart to allow you to rebuild.
Of course you can have a go on it based on these pictures and the YouTube clip, but i think it will be very hard to do so. I have no clue when instructions will become available, sorry for that. Enjoy!
Hi Eddy. The trailer is NOT the trailer from the LEGO instructions. However, i took the official B-model as a starting point to create the one pictured here. I cannot tell for sure what changes i applied, because this model was made about half a year ago... I do remember: 1 ripping out the crane part from the trailer. 2 Lengthening the puller by one stud, to make the XL motor for driving fit, and reinforcing the gear to diff with an L-shaped beam. 3 fitting in the M motor for steering with worm. 4 designing the lift mechanism with worm at the front of the trailer (took most time), and fitting the second M motor on the puller to couple and lift the trailer. 5 reinforcing the neck of the trailer with diagonal beams. 6 adding the 'spoons' to the trailer, and the mechanisms to lift and lock them.
So i think that the size of the standard trailer is actually ok already.
Hoping this helps, good luck!
Hi, you already stated that you only used the set parts, but there is a question left for me: I also own both displayed sets (excavator and tow truck), and I also want to fit the excavator on the tow truck, so I wanted to ask if you have changed anything else during build-up-phase of the tow truck to fit the excavator on to the loading platform, or did you build the trailer exactly as described in the plan? Thanks!
