Volvo A40F articulated dumper
A short demo of my 1:14 scale Volvo articulated dumper 6x6 wheel drive. The dumper tipping mechanism is a spindel motor system from Carson Germany.
The drive motor is a 6 V geared motor from Conrad electronics. The articulated turning mechanism uses 2 13/70 electric cylinders from CTI Germany. I may be swapping the electric cylinders with real hydraulic ones. Here is a pic of it beside a Fumotec model to the left Last edited by kenobi; 12-30-2013 at 01:56 PM. |

Re: Volvo A40F articulated dumper
Nice work Kenobi. Are those Tamiya axles you are using?
I'm trying to decide what to build next and the A40F is something I might like to do...

Re: Volvo A40F articulated dumper
Great cinema. Good idea too turn with cti cylinders. I think it's an option for my next Volvo-dumper.

As regards the CTI cylinders, they can be a bit hit and miss and I can not yet figure out why they sometimes do not work. Some days they work without a glitch , other days they suddenly stop working intermittently. Each cylinder piston is capable of 4 kg push and pull , that's 8 kg working together which should be more than enough for steering. I am running them on 3 Cell lipos but I am tempted to try 4 cells . |

Re: Volvo A40F articulated dumper
A really nice model. Dump system speed is very prototypical and smooth. I don't have any personal experience with the CTI cylinders but have seen them used in a variety of applications. Let us know when you find out what is causing the occasional problem.
Love the sound system and lights! Ken

Yes, they are regular tamiya axles.

Re: Volvo A40F articulated dumper
Definitely a great looking model! It seems very well built and scale as well. No lack of traction either, climbing over the boots and weights you laid in it's path. Is the model built out of metal and styrene?

Re: Volvo A40F articulated dumper
I had no idea it was all metal! Very cool! Usually the mass produced kits we see have the complex parts, like the cab and hood, made out of mold injected plastic. It's incredible to see everything made out of aluminum. The A40F looks beautiful in it's raw state! I know this isn't a mass produced kit. The original builder must be a master with shaping aluminum.
