Wheel Loader
--------------------------------

This Wheel Loader MOC is the work of Nico71 (
http://www.brickshelf.com/cgi-bin/gallery.cgi?f=321076) who has presented a wonderful set of photographic
instructions.  Using these instructions, I built the MLCAD file which is also presented here.


- Drive:  The vehicle is 4 wheel drive and driven by a single Power Functions XL motor.  There is a
differential on both the front and the rear axle.  There is no center
diff, so the front and back must always be driving together.

- Steering:  The vehicle steers with a worm driven articulated chassis turned by a Power Functions M
motor.  The steering wheel in the cab turns with the vehicle
steering.

- PF:  There are two motors, the PF XL and M mentioned above.  The body also contains the 9V battery box
and a single IR receiver allowing remote control of the
motorized functions.

- Bucket:  The bucket lifts with a pair of parallel pneumatic cylinders and dumps with a single pneumatic
cylinder.  The pneumatic pressurization system is not on board
so there are no switches.  An umbilical provides the air pressure remotely.

- Statistics:  About 900 parts.  3 pneumatic cylinders, 2 Electric motors, 1 IR receiver.


I made a number of renders of this model.  The first two just show the WIP as I built the model.  The
others show variations of radiosity and HDR settings.
