1:50 Dragline

[modelman]

Rvjimd-"tight lining" means carrying the bucket in close to the boom after it is loaded. This action on a real dragline would cause the hoist & drag motors to overheat and severely damage or possibly destroy them. Also remember that they are carrying 100's of tons of dirt with each bucket and this also puts extra stress on the hoist & drag ropes. The correct action is after the bucket is loaded you let out the drag cables until the bucket is swinging freely under the boom-point. Even to the point that you are spilling a little dirt as you swing toward the spoil pile. If done correctly this takes all of the stress off the motors and some off the ropes. If you watch videos of some good operators you can see this is the way they work. After the bucket is loaded they let out the drag cables as far as possible without dumping and then adjust the height of the bucket as they are swinging so they are ready to dump as soon as they reach the pile. It takes a little practice to get all the motions working together but then it is really fun to watch. Also with your ingenuity I think you could make the big gear turn off one of your drums or servos which I think would make the model even more realistic... Have fun!!
