About me

  Drivers cab, rear end, and a few details.

The cab is one of the more detailed areas on the carrier, and also time consuming. I will not make an exact replica of the real LTM drivers cab, but let the artistic freedom rule a bit.

I also need to make the rear end some how..

  First a regular dash board from a Scania R260 was made 23mm wider, and the seats from a Knight Hauler were modified.

  Seats got a new base..

  The ends on the dash board were modified as well to fir the new cab.
Seats show early stage modifications: Seat belt locks.

  The finished seats! Arm rests, control panel for seat adjustments, seat belt lock and guides, and a base.
Actual seat belts will be added after paint.

  The lower part of the drivers cab got a tray with holes for cups, steering column for the steering wheel, brake and speeder pedals, and various other details.
Six small SMD LED will go into the dash board later, after paint and stickers.

  A lot of details are missing, but I am sure that you get the picture.
Looking into the pipeline reveals a coffee machine, navigation, newspaper, CB radio, telephone and things like that.

  The wall behind the seats are the beginning of a double wall so I have somewhere to hide wires etc. for the rotary lights and position lights on the cab, and the interior lights that will go into the roof of the cab.
The tab in the middle will serve as a guide, while the two cut-outs will hold a cabinet, hiding the nut for the rotary lights on top of the cab.

  Here both halves of the cab have been put together, including the double wall.

  A look inside the passenger side!

The carpet that will go on the floor later will extend into the 2mm gab between the round base of the seat and the floor, thus holding it in place.
For the same reason, the seats cannot be glued in place just yet.

  -and the driver side! Not complete, but getting there..
The inside of the doors will be covered by a thin sheet once the windows are on place, after paint..
That way the clear plastic windows will be held in place like a sandwich, and not just glue.

  Note the nut in the corner of the sealing. Not THAT pretty, right?

  Note the back wall of the interior unit. It'll hide the nuts and wires! (See next image)

  Like so...

  The mats on the floor is actually the hand grip rubber from an old camera lens, cut to fit.
It has little squares, and lookes like a real floor mat up close.

  Cab, mirrors, seats, CB radio, walkie talkie, smartphone, steering wheel, and a white binder incl. real paper pages!

  The little binder is made by heat-folding a piece of thin trivet plastic, and stacking a bunch of "A4" paper sheets inside.
A small hole in the back, a few markings with a marker, and you're done!

  Right door interior, including pocket and handle.
Left door interior is similar.

  Got the paint out!
The yellow color is the actual RAL 1007 chrome yellow that Liebherr cranes are painted in.

On the right: Clear plastic sheet + H-shaped rubber seal for windshield and windows!
Also: Three windshield wipers, rotary lights, antenna, black corner-protectors for the cab, mirrors, and the almost finished inner cab module.

  Door interiors.
The one with the paper in the pocket are for the drivers side.

  A rare angle of the drivers cab, revealing the CB, navigator, walkie talkie, smartphone, and even a letter!

If you look careful you can also see a few of the six SMD LED's on the dashboard. There are one blue for the high beam, two green for the turn signals, and three red ones to indicate external power, work light on and rotary lights on. I'll get back to those later.

  If you look close you can see four clear LED's extruding from the lower side of the upper cabinet. Those are the cab lights, and are 3mm "warm white" LED's.

I intend to select a resistor about two or three times the minimum value so the light will only just light up the cab, and not look like a football match a mile away. :-) Such details are important, but often neglected.

  A look at the drivers side, all details painted!

  A look at the passenger side, all details painted!

  Got the grey paint out! This is THE grey that Liebherr paint their stuff in: RAL 7012.

(I try to get as much painted now while the weather is warm and dry. I cannot paint during the winter, cause my garage is too cold, and because it smells too much if I paint inside the house.. So: Paint now, mechanics later..)

  Back at constructing the cab: Fitting the glass! The clear glass goes in between the door and the door trim, and is held in place like that.

  Look inside the cab at the driver door: Door trim and glass fitted!
-and so is the rotary lights, antenna, front markings, corner protectors, windshield wipers, mirrors etc. The little round things right above the windshield houses small, white SMD LED's. (Position lights)
The green shade is actually a small sheet of transparent plastic fitted on the inside of the actual windshield, so it look more real, and does not get stuck on things. Without this shade, the windshield looked like one, big shopping window..

  In order to maintain the same wire colors, methods and not least the overview, I sat down and soldered all lights in one go. Front bumper, rear bumper, indicators on the dashboard, cab light, rotary lights, position light on the roof, wires on the electrical panel (rear), and the light at the rear license plate.

  -and that completes the cab module!
Both inner- and outer part + front bumper and base plate together for the first time ever.

It will now go on storage until the rest of the carrier is complete.

  Wires will go into the chassis, and will be invisible later on..

  Wanna drive??
Everything's there, from the pedals on the floor to the CB, navigator, and the six little SMD LED indicators in the dashboard, walkie talkie, smartphone, binder size A4, push buttons to adjust the seats, operate the windows, and more....

  A few papers have been forgotten in the door pocket...
Also shown: The fuse box to the left of the steering column.

  Passenger side.
Note the glove compartment..

  Showing the cabinet above the seats, that hides the nuts and wires from the rotary lights, and holds the four interior cab lights.

This image is also a revealing close-up studio of the paint quality. The paint is regular Motip spray, normally used in the automotive industry.

  I also got the brass work back on track, and made two brackets to go on to the rear, holding wheel locks.

A 2mm round brass bar was bent into a big U, and soldered on to a piece of brass bar.
The assembly was then glued to the rear plate using epoxy.

  The wheel locks are excellent molded copies, bought at http://www.rcbrmin.com/
They needed absolutely no additional work, such as filing, sanding or paint.

A similar set are found on the other side.

  The finished module!
The license plate is lit, as are all lamps in the bumper. The lamp glass was glued in place and masked using tape prior to paint. That ensures that the assembly does not leak any false light.

License number: "10" because I live in police district 10, and "09 12" because I began building the crane September, 2012. :-)

  The little yellow electrical warning is not lying..


The cabinet does hold electrical stuff! Main on/off using a key. The power selector is here, and the entry point for battery charger, external power, and two related indicators. The eight clear indicators are for the outrigger microprocessor control, and I will come back to that later.

The bottom is used to hold tools, and a plastic separator ensures that no tools can get in behind the control panel. Wires from the bumper are protected by the orange straw..

  More wires...

This module will be bolted on to the rear end of the chassis later on, but for now it go on storage until the rest of the carrier is complete.

  Remember the exhaust that I made from a grey plastic tube? Here it is again, now painted with chrome paint to illustrate a chromed, steel exhaust.
I can't wait to see it along side of the other things from the engine area!

  It's suspension-time!
Most of the pendulum suspension, cardans and servo brackets are here.. Ready to go on the eight axles.

  While waiting for the grey paint to harden on all of the suspension parts, I began masking the rims / wheels.


The entire rim and tire was masked off using masking tape, and then the aluminum rim was cut free.
A round sticker (Ø 19mm) covered the very center, where some tiny M2 threads are, for the hub covers.
When the yellow paint has hardened, I'll scrape the little specs off that got on to the rubber tires.

Note the now assembled suspensions on the overturned chassis in the background.

  This was cut from a 12mm thick aluminum sheet on the CNC, and is the support bracket for the crane boom when in the stored position.
Here seen from the front.

  -and from the back.

  The micro switch detects when the crane is in the stored position, and only then will the support legs be operational.
This security feature are supposed to prevent that I accidently operate the support legs via remote, and only too late realize the mistake.

  This is one of the back panels, and I went ahead and fitted the checker plates according to the original.

MANY more details followed.
