A linkage for a stretcher suspension. The linkage includes a stretcher receiving frame 17 and a base frame 23. A pair of arms 10 are pivotally fixed to bottom frame 23 and slidingly connected (12, 14) to frame 17. A pneumatic suspension unit 33 is located between the arms 10 and a first link 27 pivotally coupled between arms 10 and frame 17. A cross member 12 of the slide coupling is coupled to a sliding mount 25 of a second link 24 pivotally coupled to an arm 18 pivotally connected to the frame 17 and sliding coupled (21) to the base frame 23.
