you need to hold them,they are throttle lever XD
the cable move only when 0.5 or -0.5 to prevent player accidentally press them

I pressed them and nothing happened

Okey,HUGE SORRY for the mistake!
I accidentally placed the pivot all the way across the connection point
thank you for find that out : )
But the cable system didn't seem wrong for some reason,what happened to the cable control exactly?

Well it worked but the button that tighten and untighten the cables in the crane cab Dont work and when i was trying to unfold the crane it was trying to flip and i had the supports out

Alright

to setup the counter weight you just need to move the rear of the crane above the counter weight and lower the cable,connected and raise it up,then lower the grabber and ones it's connected,raise the grabber up and is all good to go

grab is mean hold the E or Q and you will have a better chance of not connect on to the wrong connector :)

follow the steps :
1.Make sure all the cable magnet is at where you can grab them when they are loose though
(this is why there are two security magnet on the Y-shape guying system)
2.Loose the cable on the Y-Shape guying system
3.Lose the cable and grab them,turn off the security magnet it is connected on,pull it all the way to the tip of the crane and connect it to the one it should be connected.(left and right connector is for the guying systeam and the center one is for the main cable)

How exactly do you connect all the cables and Put the counter weights on?
I tryed yesterday but couldent figure it out
