I'm just letting you know that I have finish my latest MOC
It is based on a Manitou Maniscopic Truck.
It can be viewed at <http://www.brickshelf.com/cgi-bin/gallery.cgi?f=182576>
It features the following:
Four wheel drive with four wheel steering.
Pivoting rear axle.
Motor driven front and rear stabilisers.
Three stage motorised extending jib with rotation and pnuematic raise/lower.
Remote controlled forks.
Ancillary on board air tank.
Main remote unit with air storage, pump and five way motor controls.
It took a long time to get this machine to this stage. There was a lot of work
to make the axles with steering strong enough the carry the weight of the
machine. There was also big problems with balance. I managed after significant
gearing down, to get outriggers that would take the weight of the machine and
therefore improve stability.
I know that the three stage boom is slightly bulky, but it works very well with
less deflection than on a two stage at that length. The forks can handle limited
load, due to the micro motors, but they use a lighter and tidier cable, than a
pnuematic alternative. One neat feature is the way that the excess cable for the
for fork tilt is neatly dispensed as required.
The pnuematic 4 gang cylinder for the main lift of the boom really struggles if
there is any extension of the boom. Such to the extent that there would be some
compression of the cylinders at certain angles. I guess that's why hydraulics is
generally used.
I would welcome your comments. Is anyone prepared to develope the concept
anymore???

| (...) Great job Mervyn! That looks quite involved. I am not familiar with that model, but it looks like a telehandler crossed with a mobile crane. It is definately more complex than the telehandler I did (in the "previously featured MOCs" section of (...) (19 years ago, 19-May-06, to lugnet.technic)
