Does anyone know why (at least on the nationals) the turn circuit is reversed from swing cab to stand up controls? I.e. push away for right on swings and push away for left on stand up... even joystick setups are like that...just curious.
 
I haven't run a swing cab national but the stand up units (900H) are push away for right. I would believe that maybe when national started building stand up units the main side to stand on placed the swing circle on your left side so pulling the lever towards you brought the swing towards you.

Or maybe there's some completely different complicated reason it's that way.

I was surprised it just didn't remain the same across the board...i'd switch the lines....lol. still looking for the answer, along with the ring with the slot on the national boom rests...

Would that be the swing away control station that utilizes the joystick style controls?
 
The right side on a swing...either on a dual station stand up...what are you getting at smittie?
 
If I remember correctly when in the main operating position you push the lever to rotate toward the direction the boom is on.
 
Hmph...then it gets back to dual postion cranes being the wierd ones i guess. Makes sense...back in the day their was probably only one station to work it from.

On my old crane when the control was on the driver side ,boom to my left pushing the lever forward moved it to the boom side. The controls would then swing to the other side and operate the same direction. of course this was with only the 1 set of controls. Of course with my remote it depends on where I'm standing:)
 
What Mark says!! Move the leaver up and the boom will rotate to whatever side the boom is on, in regards to the operators seat. They taught this is crane school. I was trained on a stand up terex with controls on both sides. Never noticed anything, but when I bought my national with a swing cab, that is the first thing I noticed was the boom rotation was opposite of the terex I was used to running.

PCSA standard control configuration on all swing cab cranes require you to push swing lever to move cab toward boom and pull swing control to move cab opposite boom location. works the same weather you have a left or right mounted cab, relative to the boom.

push the boom away from you, pull the boom toward you.
