I managed to get the whole drive line connected (16 x 8 ). Space was very tight, but it works. Next : connecting the steering system and the motor with the main gear box.   Kerst

Here the latest update on my LTM1800. Work during the summer was slow, but since then I managed quite a bit. I decided to add a quick connection rim to my slewing ring. It looks great on the real machine. Sarens has one with this option, but this is a LG1550. The logical next step was the super structure frame. I decided to use aluminum, mainly to reduce weight. I found excellent epoxy glue and so I laminated the sides. In places with lots of stress I use bolts. The carrier is obviously not quite finished, the main motor and gearbox are missing, so are the outriggers and lots of details.   To be continued, Kerst

Thanks for the compliments, everybody! It is nice to be able to share the progress here. It will be a while before it is going to be finished, I count on 6 - 10 years total depending on what life brings me, but the actual building is for me more important than the finished product. Kerst

It has been a long time since my last update, I did not have a lot of time, but I did some work. I spent from last November on the outriggers. This is probably the most complicated part of the whole crane, because they are going to function. I found some very small, but extremely high torque motors, which easily fit inside the beams. The issue was to transmit the movement effectively to the cylinders, from horizontal to vertical. I first made one outrigger assembly to try the design out, then after testing I redesigned it till it worked and fitted satisfactorily. I tested this outrigger to 10 lbs and it did fine. Now I am working on the others. The first photo shows the mechanism on the outside of the beam. This illustrates how it works. The mechanism will be hidden for the rest of its life inside the beam.    Kerst

A little progress: I finished the outriggers and they work! The clip shows them working. The steering is also finished and the only big thing to be done is the main motor and gearbox. I did some detail work on the cab, but there is still more to be done.  http://www.youtube.com/watch?v=i1kol40B3owKerst
