The Medevac II series is the most widely used helicopter rescue litter. Currently in use with civilian and military operators worldwide, including all branches of the US Military, Japan Self Defense Force, Canada Department of National Defense, Royal Australian Army, and is standard equipment aboard all US Coast Guard helicopters and rescue boats. The Medevac II is a modern Stokes-type litter constructed for long life in the marine environment and is available in two models; a rigid frame (Medevac II) or break-apart frame (Medevac IIA).
The Break-Apart model occupies approximately half the stowage space of rigid litters. Screw-couplers with self-aligning pins secure the top tubes firmly together, and the lower skid tubes attach with hook and pin-type fittings permitting quick assembly. Both top tube and skid couplers are cast or machined from solid stainless steel. This coupler system is the strongest in use on any stretcher today. When assembled, the Medevac IIA Break-Apart is as robust as the rigid Medevac II, proof load tested to 2,600 lbs with no yield.
The lightweight Titanium Medevac IIA model share the same design as the stainless steel models, but are fabricated from aerospace ASTM Grade 9 (TI-3AL-2.5V) titanium tubing and components. Use of titanium provides a 40% reduction in frame weight, increased mechanical strength properties, and improved corrosion resistance compared to standard steel and stainless steel litters. The weight reduction is a significant benefit to aircraft operators, providing an increased available payload for additional equipment and/or reduced fuel consumption. Ergonomically, the lighter litter results in significantly easier transport & handling by rescue personnel, making the titanium models ideal for remote area and mountain rescue operations.
The Narrow Flotation Kit #103-TI reduces the width of a litter with installed flotation by 4″. The narrow profile is accomplished with half-width, “D” shaped flotation logs and a foam back pad. Flotation tests have been conducted on LSC #406-TI Medevac IIA litters only. Other litters will require testing prior to placement in service. Components in the flotation kit are constructed from high quality synthetic materials, and are suitable for the marine environment. When properly installed, the added flotation kit provides positive self-righting and head-up flotation characteristics. The included retainer straps prevent fouling of the patient restraint straps during in-water rescues. Covers for flotation components are international orange, and are available in black by special order.
Both the Medevac II & IIA litters are offered with polished Type 304 Stainless Steel and the IIA model is available with lightweight Titanium frames. The tubular components have a wall thickness that is 30% greater than that used on other MIL-SPEC & commercial litters for extended service life and durability. Included with each litter are five (5) color-coded patient restraint straps with LSC’s exclusive, double locking Quick Release Safety Buckles.
