Abstract

A litter comprising two arm shafts. The first arm shaft being the lock receiving frame arm and having a first locking member and a locking shaft having a second locking member. The second and first members interact to releasably retain the two arm shaft adjacent one another. Strap retaining means, each interacting with a strap, are place separately along the first arm shaft. The second arm shaft is a strap receiving arm with at least one ratchet dimensioned to receive a strap. A one torque limiter prevents each strap from being tightened beyond a preset tension point. A ratchet shaft, with a handle, is within the second arm shaft and in rotatable connection with each ratchet. Each arm shaft has a lockable handle rotatable around each end, able to rotate to serve as handles or legs.
