Oh, we of little faith! Having spent some time last night playing with my
banana peels with their little click-hinged plates, I can say that they are
a lot stronger than we thought.
Test 1. I built myself a little vertical wall of 1x8 bricks (about 8 high).
Underneath this stack, I attached a plate-hinge on each of the two ends. The
plate is 1x2 with one stud and one hinge to connect to the banana peel. I
put a 1x6 plate between them (to stop the hinge plates from swivelling on
their single stud. (The purpose of the wall was to give me something to grab
to do the Hand of God lifting).
Then I started testing how much weight the two forks (banana peels) could
lift without falling off. The stress points are the stud-connection of the
plate-hinge to the bottom of the wall, and the click hinge itself connecting
the plate to the fork (banana peel).
Results of Test 1.
I found that the forks could lift a payload built from 25 2x4 bricks, but
only on the initial lift. A couple of repeated up-and-down liftings (i.e.
jiggling it about a bit) caused the hinge plates to detach from the bottom
of the wall (i.e. the stud connection broke, the click-hinges remained
connected).
I experimented with reducing the number of bricks in the payload, and found
that at about 15 2x4 bricks, the forks could successfully lift this weight
and survive jiggling about. (Note too much jiggling makes the brick pallet
fall off rather than damage the "fork lift" itself). I was actually very
surprised at the strength of the structure, given that each fork-plate pair
was held onto the bottom of the wall with only a single stud.
Test 2.
Since the single stud connection under the wall had been revealed to be the
weakest point, I decided to strengthen this by adding a 1x8 plate across the
bottom of the whole thing (i.e. immediately above this plate is plate-hinge
(only 1-studs-worth of connection), the 12x6 plate mentioned above and then
the other plate-hinge. This made the hinge-plate very secure (i.e. not easy
to pull apart), and I theorised that the weak point would now be the
click-hinges themselves. I suspected that too much weight on the forks would
cause the click-hinge to come apart and the forks to fall off.
Results of Test 2.
I gave up eventually. By the time I had worked up to a payload of 50 2x4
bricks on the forks, the forks were showing no sign of falling off, even
with jiggling. By now, the payload was getting too physically bulky to let
me get my hand onto the wall to lift it, so I abandoned the experiment. C
Conclusions.
Click-hinges of the banana peel are remarkably strong, and even their single
stud connections are stronger than one might expect. With a plate across the
bottom to secure the hinge plates into the vehicle (or whatever), the forks
are slightly lifted above the ground by a plate-height (but you need this
for ground clearance anyway). These forks have no difficulty lifting a large
block of bricks (that is, a scale model could easily carry the appropriately
sized payload).
So, there was some benefit in buying Anakin's Podracer after all. I now have
some nice forks for a forklift.
Does these forks (banana peels) occur in any other sets? For example, any of
the actual forklift sets?
