TM 1-1520-240-10 6-4-2            6-4-11.  Litter Support Brackets. Refer to figure 6-4-5 for litter installation. Four litter sup- port brackets are permanently attached to each litter pole and each litter strap. The brackets are spaced 18 inches apart. A locking device in each bracket secures the litter handles in place. The locking device consists of a handle clip,  a  slotted  locking  bar,  and  a  locking  handle.  The locking handle is hinged to the lower jaw of the bracket. The slotted locking bar is hinged, cam fashion, to the locking handle. The handle clip is hinged to the upper jaw of the bracket and has a hook end which is engaged in one  of  the  slots  in  the  locking  bar.  When  the  locking handle is moved down, it forces the locking bar up and releases tension on the handle clip. When the locking handle is moved up, it pulls the locking bar down and forces the handle clip to a positive grip on the litter han- dle. 6-4-12.  Litter Poles and Straps. Twelve litter poles are provided for use in adapting the helicopter for medical evacuation. An attachment fitted to the bottom of each pole has two indentations, on oppos- ing sides, which fit between two studs located in a floor channel. The upper rear side of the pole contains two keyhole slots by which the pole is anchored to studs on the seatback support tubes. A metal spring retainer in- side the pole locks under one of the studs when the pole is installed. This prevents accidental dislocation of the pole. The retainer is released for litter pole removal by pulling the grommet which protrudes from the front of the pole. When not in use, the litter poles may be stowed at station 120. Twelve litter straps are used with the litter poles to sup- port the litters. The straps can be adjusted upward or downward by slide adjusters near the upper and lower ends of the straps. All of the straps are fitted at the top with slipover hooks which are fastened to brackets in the strap stowage recesses. The lower end of each strap has a fitting for attaching the strap to a tiedown stud on the floor. The straps are stowed in the overhead recesses directly over the floor studs to which the straps will be attached. The stowage recesses are covered with can- vas flaps which are zipped along two sides. 6-4-13.  Litter Loading. The loading of litters will be accomplished through the lowered aft cargo door and ramp. The forward litter tiers should be loaded first, top to bottom, then progressively rearward. Litter patients requiring in-flight medical care should be positioned to enable access to injuries requir- ing attention. If the helicopter is to be loaded with a com- bination of troops and litter patients, the litter patients should be positioned to the rear of the troops.
