Its working!
Now a number
of functions of the model can be controled by the remote controle. :)
But
still with the the wires connected and turned off transmitter part.
The pump, all outrigger motors, outrigger cilinders, boom cilinder and
swing are functional.
Now its time to organize the wiring.
For the CNC
machine I ordered several parts so I can use it with aluminium.
The revs where to high and working with aluminium didn't result in something
I wanted...
In the weeks
before I have been wrestling with the modules.
I discovered that the Robbe Futaba F14 transmitter has a lot of radio
power.
The modules get crazy from it!
So
now I will make a wire between the transmitter and receiver and see if
that works, without modules switching when they want and not when I want
them to switch...
In the mean while a lot of time is lost because of it.
Today the
mailman brought the switch modules I ordered.
To be able to control all functions of the model I needed switching modules.
After a long period of deep thinking, I decided to go for the RC8plus
base print and the ERW-4MS optional print from Modellbau-City.
And the switches for the transmitter.
But then two of all!
A BIG investement...
On a later moment I will explain how I think to use them and for which
function.
RC8plus gives
16 switch channels and 4 proportional channels over one transmitter channel.
The ERW-4MS module can switch 4 motors (2 directions and stop) and 4 proportional
channels.
I have to read all documentation so give me some time to explore everything!
I had to
think some time about how I would make both SSL arms.
Demag didn't use a normal recangular profile but a different form.
Because of the dimensions of the arms it was not possible to make them
from solid material, it would get to heavy.
So I had to bend sheet metal myself.
I formed two strips of 1mm thick metal over a length of 90 cm.
After
that I welded both strips together over the full length.
The result:
From this
side it looks like a normal profile.
On the other side you can see both welds.
The first rough grinding is done.
And the result
with the welds on the left top and the right side.
After this more grinding has to be done ofcourse.
Then I will cut of the two parts I need and connect them to the rest.
(The pictures
show a distorted view)

Thanks to Richard I had enough picture to start working on it.
These are the motors, 10mm in diameter, that will drive the cable drums of the SSL.
2005
On the moment
I am working on the SSL unit.
I have a lot of pictures and a few drawings, but not every detail is on
them as clear as I would like.
There seem to be different versions of the system, that makes it more
difficult.
Here two pictures of this moment.
2005
Its time
for the next update.
After a great Modelshow Europe are here the most recent pictures of the
model.
As from 2005
the model has the livery of De Gier from Rotterdam.
The change has had several reasons.
On the frontlawn with fully extended main boom.
During the Modelshow europe the model had a wheelloader on its hook, the
same like the real crane during the Openhouse of Kuiken-Cramat.
Complete with working signallight on it.
Unfortunatly the SSL and the ballast adapter plate aren't ready yet.
The sheaves are on more then 3 meter hight!
With the boom in an angle of 85 degrees.
The counterweight, good for 13 kilo!
All plates are separate and have the same form as the original.
On the moment I am working on the telescoping mechanics.
After that
I will instal the electronics needed for the Remote Control.
I will also start working on the SSL unit and the detailing of the total
model.
2005
One week to go for the modelshow in Eelde....
I am working
every minute to get the model in top state for the show.
It won't be ready but in a better state then last year.
The livery has changed and that is the reason why there haven't been any
resent pictures of the model here.
After the show I will make it up to you all.
This is how the ballast looked like one week ago...
I asure you
its looking better now and its lying on the frame on the back of the crane.
Now you can see its going to be a model crane. :-)
Also I made the lifting points in the side of the plates.
Now the several parts have to be combined, prime them and spraypaint.
As soon as they are in the basic color I will put here some pictures.
First I am working on the normal counterweight, in a later stage the extra blocks and plate will follow.
2005
It is only on slow-motion.
Other things demand a lot of my time.
During the Modelshow Europe you can see the new livery of the model.
And for people that can't be there I will show it here.(after the show)
By feeding a 3D CAD drawing into its notebook, it makes the part automaticly.
Great machine but it takes a lot of my building time.
The arm is working as it should, so work can go on!
Last week
a delivery man brought a package.
Looking at the mans face it wasn't the biggest but shurely the heaviest
for him today.
It
was the ballast kit.
Everything beautiful laser cut, something which would have taken me a
year.
Here an overview of the parts making the different plates.
As you can
see all plates are made of several parts to get the right shape and thickness.
In a week I will start drilling the holes in them and finnishing them.
I didn't
go to the openhouse of Convoi.
But I played a litle soccer with my son. (playing soccer for the first
time in my life!!)
And i went down and teared a muscle in my right elbow.
Now I am the proud owner of piece cast around my right arm for the next
week.
Then some exercises....
No working on the crane or going out to take pictures. :-(
Just yesterday
I ordered a company to cut the counterweight plates with CNC Laser.
They said that it would take 12 working days to be ready.
I can't wait to see the result!
Maybe I
will go to the openday of Convoi but its a three hour drive, one way.....
You can see the pictures here when I have been.
On the moment I am working on the SSL unit and the undercarriage suspension.
The modelshow
of Geldermalsen is now more then a week ago.
I can look back on a very succesfull day.
Many visitors came at my table and showed a lot of interest.
Here are some pictures.
At this moment
I am working on several parts at (almost) the same time.
These parts are:
-The counterweightframe
-Hydraulic system
-Plating of the undercarriage
-The telescoping system
-The wirering
-Both cabines
The hook and the counterweight plates are also on the To Do list.
Depending on the drying time of the paint and glue, and the received information and materials, I am working every free moment on the model.
This to let everybody see a recognizable crane model on the show in Geldermalsen in April.
The next weeks there will not be many new pictures to keep the suprise.
Hereby I want to thank the driver of the Convoi AC350SSL for the support he is giving me with detail information!!
Here the first picture of the boom head.
And the base part of the boom has got some more details on it.
I couldn't resist to put the boom on to the superstructure.....
To get an idea of the size I put a tin can on the model.
I have planned
to fix the boomhead to the boom this weekend and make the sheeves for
it.
I will be putting several details on to the boom.
For example the SSL top cilinder mounting, cable guidens rolls etc.
As you can
see on one of the pictures I received the cable.
It has 7x19 wires in it and a diameter of 1.35 millimeter.
Unfortunatly
I haven't been able to do much work on the model the last month.
The time I had, I had to make to telescoping mechanism new, because of
to big tollerances I didn't work good.
I have done some work on the boom sections as you can see on the pictures.
To get an idea.
Last wwek
I have been working on the telescoping mechanics.
Everything goes as I planned, it only takes a lot more time.
But better slow than make things three times before they work.
It will be a while before I can show new pictures.
In the meanwhile I placed the cabine doors.
I have also
been to the openhouse of the Terex Demag works.
It was a wonderfull time and I saw everything and took pictures of it
all.
Only I am not allowed to put them on the site......
More in /Aktueel/ for
now only in dutch.
On this moment I am busy with the technics which will move the different parts of the telescopic boom.
I haven't had much time to make great progress.
But next week I will visit the open house days at the Terex Demag factory in Zweibrücken!.
As soon I have got time I will put some (of the propably hundreds) pictures on the site.
The first
two boom sections.
Pictures
of the superstructure.
Last week
I have been busy forming the plates into the desired shape.
These pictures show the raw shapes.
The profiles are to long and need more work.
The ends are deformed because the "brake" was to short.
On both longsides I have to remove a strip to get the correct measurements.
On the last
pictures you can see the outer section as it will be, only a bit shorter.
It is 8 centimeters wide, 8.5 centimeters high and 100 centimeters long.
I have also done some work on the superstructure, more info will follow soon.
The sheet
metal for the telescopic boom is waiting for me at the metal company.
Next week I will do an attempt to form the metal on a length of 1.1 meter.
As soon as there is more to see, you will find it here!
Today I did
the first tests on making the boom myself.
Here you see the first results.
These parts
are 10 cm long, max.
The boom parts will be about 80 cm long.
