I recently completed my 8258 Crane Truck from POH (Parts On Hand). I only bought parts I did not have, and sometimes that meant I needed to change some colors as I did not have all the panels in all the colors called out for the model. I tried to integrate the different colors to make it look like it could be just an alternate build, not a rainbow.
I first examined my inventory via BaseBrick to determine what I had and the I needed to order. The only thing I did not have that I did not order was the hook as it was listed for $16 and up on USA sellers on Bricklink, I decided then that I would just build a hook. All-in-all I spent about $20 for parts I did not have. Pretty good to be able to build the Crane Truck.
I then pulled my parts and organized them, much as I would if I had the actual set. I waited for the parts from Bricklink to arrive and then started to build. I took me about 13 hours over 7 days to complete. Maybe a little longer than some would take but I took time to study a number of sub-builds and the gear box and distribution up the crane. Hopefully this will help me to learn more for MOC’s.
During the build and after completion I studied the model and formulated some opinions.
This is a really nice model, I am glad I took the time to build it. (Again!)
The gearbox is great in how it works and distributes all the mechanical functions.
The crane arm is fantastic! It reminds me of the arms used in robotic construction and as such it could be used as a basis for an arm in a MOC.
The outriggers use quite a few parts. Not as many as the 42009 but seems like more than the 42043.
The model appears quite fragile, not like some of the newer large models. It seems the the 42009 and 42043 are both more sturdy than the 8258. Maybe with the addition of 300-400 parts in the right locations the model could be more sturdy (this is beyond my design capabilities).
Sometimes some of the functions don’t work quite right, particularly when they reach the their limits. An example is that when either the lower boom or upper boom reaches the limit, it sometimes causes the crane to try to rotate, which is understandable considering how the mechanical power is distributed through the turntable. It is very clever, but maybe could be designed differently.
I really don’t like the fact that you need to reverse the motor to reverse a function. I much prefer the new way of reversing functions by putting the function selector in the opposite position to reverse, much like the 42042 Crawler Crane, 42055 Bucket Wheel Excavator and the 42054 CLAAS . But this is the way the 8258 was designed in 2009.
Excluding the quibbles in items 5, 6 and 7, this is still a fun model and I would do it again. When I disassemble this model I will most likely store it as a set so when I decide I want to build it again I will not have to hunt for parts in my POH.
During the build I applied Designer-Han’s modification number 3 to the PF-LA brackets. I really could not see what the other modifications would help, so I did not use them.
My favorite parts of the model are the gearbox and crane arm
Overall I would give the model a 9/10 (an A letter grade) for a 2009 set and a 8/10 (a B letter grade) compared to 2013 to 2016 released sets (particularly the 42009, 42043 and 42054).

From the photos you can see how I changed the colors. I tried to substitute colors where it made sense. I replaced the cab top with all black (because I was missing the red side panels) , and the crane arm with black for most of the the yellow beams and red panels for yellow ones. The yellow beams on the third section of the area were replaced with red because half of the arm was already black and I thought red would look better there. Also the red panels on the cab back and covering the controls were replaced with black, because I did not have the red rectangular panels.
Also notice that instead of an expensive hook I just used the hook from the 42009… I think it looks OK, particularly since I don’t plan to hook anything anyway.
I hope you find my Crane Truck pleasing to view.
