its not the cable thats the important part ( thats easy) its making the movment of the lift car and the counter weight ballanced out

they need to move in sync with eachother over a set distance with a single input ( button push?)

once you have THAT working then your 2 cable models ( with origin at ONE end ( i'd use the top end) are easy

vertex attach cables to the top assembly
vec distance to verx location on top of car lift and top of counter weight from origin point of each cable connection point . using that vector set the correct angles and scaled distance of each cable for direction and length

one problem you will have with this scalling method is skin texture compression/stretching if you use a patterned skin on the cable
