Suspended transport system (5,3)
I believe the answer is:
cable car
'suspended transport system' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for cable car that I've seen before include "Mountain transport system" , "Transport used to go up mountain" , "Skier's transport" , "could make one upwardly mobile" , "Funicular vehicle" .)
