d. Suspension Traverse. The suspension traverse is used to move personnel and equipment over rivers, ravines, chasms, and up or down a vertical obstacle. By combining the transport tightening system used during the Rope bridge, an A-Frame used for the Vertical haul Line (Figure 5-25), and belay techniques device, Units can construct a suspension traverse (Figures 5-26 and 5-27). Installation of a suspension traverse can be timeconsuming and equipment-intensive. All personnel must be well trained and rehearsed in the procedures. (1) Construction. The suspension traverse must be constructed using a static ropes. The max span that can be bridged is generally 75 percent length of the shortest rope. Planning considerations are the same asrope bridge and vertical haul line combined. (2) Equipment. Three static installation ropes. Seven sling Ropes. Nine carabiners. One heavy duty double pulley. One locking carabiner. One canvas pad.
