First MOC - 42110 B-Model: Forklift

Recommended Posts

Hi all - my B-Model from Land Rover 42110 is complete. It’s a forklift, with a design goal of minimum steering radius.

Functions: 

  • Mast, controlled by knob at the back (modified version of mast from 8416)
  • Tilting forks, controlled from main cabin
  • Steering, controlled by HOG propane tank or adjustable steering wheel
  • DNR selector at main cabin
  • Fake I-4 engine
  • Steering-activated transmission, to allow the wheels to rotate in opposite directions during tight turns, and still be “powered” by the differential.
  • Manually adjustable fork width

Video:

The functions in this model are pretty densely packed:

Here’s the steering geometry at its most extreme position:

There are no plans for instructions at this point, beyond a photo teardown - but I had a lot of fun making this! Hope you enjoy. More photos are available at https://imgur.com/gallery/3OevclL

That's an AMAZING piece of work, well done!  Even using arbitrary parts it would be impressive, but doing it from one set is astonishsing.

I might try to make the fan a little faster.  It's kind of a pity that the marvellous reversing mechanism for the steering is not more obvious to the casual observer.  If it were motorized it would be perhaps be clearer, but that might not be practical.

I encourage you to make instructions.  I'm sure lots of people would want to make this, and you might regret not having a record of it later.

Wow, this is an awesome build !! The steering is simply ingenious.

Amazing for a B model.

Photo teardown will be good. Such an MOC deserves a challenging set of instructions. Trivializing with a one-part-in-each-step baby instructions is almost irreverent to this thoughtful MOC.

A recreator will also find it a lot more satisfying build after sweating it out a bit.

Good god this is bloody well advanced. I'm amazed at the steering drivetrain reverser mechanism

Superb technic! 
this should get front paged for technic awesomeness. It looks great of course but this is technic frontpaging :thumbup:

What a B-model, just whoa!

The mechanism for the steering-activated transmission is really unique. I've never seen that before in a technic build.

Wonderful model, some real novelties in there:thumbup:. All the more impressive being a B-model. Instructions (teardown photo's) would be more than welcome!

Thanks very much everyone for your feedback! Glad you’ve enjoyed it.

Yeah, this would be nice - I couldn’t find a way without a major redesign, or a more compact piece for the fan than the cheese wedge/brick built solution. (Part of it is also that every 8-tooth, 12-tooth bevel/double bevel, and 16-tooth non-clutch gear were used).

Yes, I’ve run into this problem trying to explain to my wife. Hopefully the video makes this function clear for most :laugh:   It’s funny that this model and the A-Model both have a large amount of complexity dedicated to making a fake piston motor spin in an “appropriate” way - in that sense this B-model is in the spirit of the original.

Hopefully I can make it reasonably clear - should be ready in the coming weeks.

This was the sort of radical engineering which we used to see in some of the older Technic sets.  Take a look at the build of the fork lift on 8082 for example.  it is solving a problem in a mechanical format which would be designed differently, using hydraulic or electronic means.  Given the fact that the forklift made is only 2wd the opposing rotation to each wheel at full lock is even more important.

A great proof of concept, but don't depend on your mast when removing product from high level pallet racking!  Well done.

Very true, it feels to me like 'proper technic'.. A day when i see a new clever solution is a happy day!! As everyone has already said, this is a brilliant moc. I love it.
