[MOC] 42139 Alternate - Front loader

[TGBDZ]

Finnaly found some time and inpsiration to build a proper alternate for this amazing set - Front loader. 

Functions: 

1. HOG steering - whole front section pivots
2. Pendular rear axle
3. Working 2 cylinder inline engine at the back
4. Fully operating front boom - uses ratched mechanism to keep the desired height
5. Angle of the shovel can be changed
6. Opening doors

As there are no access to worm gear or linear actuators, the lifting capacity is limited, but still it's possible to lift some lighter cargo.

Rear axle can move freely without any suspension, therfore it's easy to overcome smaller obstacles.

Whole front section is steering and is connected via the small turntable to the rest of the superstructure that enables easy and smooth steering using gear on top of the front loader.

Just like with other alternates, it's possible to buy the instructions on REBRICKABLE.

Cheers, TGBDZ

Nice loaders for a b model.

Wow, that's something totally unexpected. Real surprise in positive way.

Nice b model.

Very original idea of making a set with no LA or pneumatic components into a construction machine :-)

Very nice Alt build of 42139.There are a lot of functions that the partlist of 42139 does not make too easy, and you designed this well with those limitations.

This was my 4th or 5th attempt at building an alternate and from all the ideas I had this turned out much better than expected

Actuators and pneumatic deffinetly helps but it's possible to make functional models with out them as well, a bit more trickier but still doable

Thanks! I was tempted to use all 6 wheels but all the ideas failed and 4 wheels did the job. Maybe I need to make a dump truck to accompany the front loader?
