Cable pulling truck

I have modeled a cable pulling truck for my electric power service company.  This truck pulls cables for under ground installation.  It took me longer than expect to build this as it has lots of small parts mostly built form scraps and wood.

I modeled this from a prototype photo shown below.  The cable pulling device is located behind the seat. Behind that are sets of storage cabinets for tools and supplies.

The photo above shows the rear of the truck loaded with supplies and tools including a small cable drum.

Above is the prototype I modeled.  The large cable drums are blocking the view of the front of the truck so I just guessed what it might have looked like.  The cable pulling device is above an open man hole so I guess it was going to pull a cable through that though I have no idea how that would have worked.

Above you can see a flat car pulling a cable to be installed in the ground next to the track, similar to what the truck would do by a road.

That does it for my electric power service company, now I need to figure out what to model next.
