the climbing ability is currently limited by the grip and the motor power. no cracking or slipping gears till yet. i have used perpendicular axle joiners(the correct description?) and my beloved Linear actuator parts to get the power from the axles to the frame. more pics when the folder is online again. next building step is the gearbox

i have found a way which it me allows to keep the frame free of gears. The third axle is connected via a torque tube to the second axle, and the second axle via a torque tube to the gearbox. so the axles could move relatively free and i hve no length changing driveshafts.the traction is good how you see in the vid. Pics are coming this day because the springs, the ground contact between the flat surface and the ascending slope is not good. but if i use a axle load balancing, the torque of third axle lifts the second axle in the air. The current gear ratio is 1:8,33 (2 times 12T to 20T and one 12T to 36T) and the xl fights at the 109% with the weight. i think i need a switchable gearbox or/and a second XL with the full weight of the finished Mog.

a spaceballs license model? picture source

you want build a trailer like this? Picture source if yes, i would use two winches with wormgear and M-motor. one winch to raise and lowering of the whole platform, and one winch to tilt the platform from vertikal to horizontal and reverse.

Thanks for the Vid. Purists will kill me, but i do it edit: it is done and it is a difference like night and day. btw, be carefull at the bottom side and dont drill to wide, or you have two holes

thanks for your answer. another question: how much load can the crane/turntable handle?

thanks mahjqa

great work sariel two questions this transclear gearbox, in which set does it appears? your double rope winch. Could you winch the ropes seperately, or both ropes only at the same time?

Hydraulics are working very precisely, but there is a big problem. It needs enormus power to push the cylinder in. i think this lies at the very small Intake hole of the bottomside. what do you think about to make the hole a little bit bigger?

looks cool, runs fine

maybe you could try rubber care lotion. in the most times it is grease, sometimes oil. i couldnt give a guarantee, but a try it is worth. normaly is a defective seal, forever defective

grindinggears, you are right. New cylinders are working perfect. i have made a little comparisation vid

Grindinggears, iam searching currently my four log loader cylinders to try it again T_tank, thanks for your suggestion. this is probably a usefull method and i will try it, if i find four not leaking cylinders. the Mini LA compressor was a easy way for the concept test and nothing final. more compact? iam not sure if this is correct hydrauliks are a big advantage for multiple axle steering. This is the only reason why i try it. edit: grindinggears, you are right. New cylinders are working perfect. i have made a little comparisation vid Edit² i have made a steeringtest with a 4x4x4 setup i think it works fine, but a little bit slow Edit³: some pics with cab 104_8220 von efferman auf Flickr 104_8226 von efferman auf Flickr 104_8225 von efferman auf Flickr 104_8223 von efferman auf Flickr

thanks for your test. i think i must select my fourteen pneumatic cylinders for the four new ones and test it again

if i use only the bottom side, then i need two cylinders, one for left, one for right, to move the wheels. to move this two cylinders, i need two cylinders. in complete i would need, only for the steering of two axles, 8 cylinders. it is possible, but the mechanism would need many space, and for the crane i need cylinders too. thanks for the idea, but it is nothing for me

Pneumatics are working, but after a few hours or working cycles, i must refill the steering circuit. now i am not sure if i should use pneumatics or the mini LAs for the steering mechanism. with the mini LAs the gearing will be a challenge

The Fluid was pure german drinking water well, the sealing of hydraulic and pneumatic cylinders is a little bit different, because they are completely different mediums. i had hoped that it works, but i have calculated with a fail

theoretical you produce a vacuum at the lower cylinder air intake when you pull the pistonrod out of the cylinder. maybe you could this use it with a hose and a dish to create your paper sucker

good evening, or should i say not so good? Hydrauliks didnt work. The cylinder is leaking at the piston rod maybe this is the only leaking cylinder, but i think using hydraulics for steering is no good idea.

good evening, or should i say not so good? Hydrauliks didnt work. The cylinder is leaking at the piston rod maybe this is the only leaking cylinder, but i think using hydraulics for steering is no good idea for my moc.

nice idea with the turntable. good for a 8x8 without portals

i will look what i can do, but first i must see with which way i mount the springs/Axleload balancing. and waiting for parts to could build the front axle.

i know. Thats the reason why i give pressure on both sides of the piston. The air is compressed before the cylinders are moving. so the Power transfer can work instantly. And the most important, if there are any leaks, off jumping hoses in example, i can repowering it without disassembling the mog. btw. i have some pics from my rearaxles. its not final but i think, something like this will it be

no prob, you was really near at the right letters. This morning i had read "Double Cab" I could make an instruction, but the cab fits to my 102x32 tires. At smaller tires it maybe looks a little bit to big. hopefully no one want a instruction of the complete moc. i have a few ideas. Knuckle boom Crane with flyjib and cherrypicker mode four point stabilizers 4 Gear transmission switchable in the cab L4 fake engine Tiltable Cab 3-way tipper Trailer Lights compressor, maybe with the lego education kit PTO we will see what i coud realise

this is an epical Moc five from five stars
