Stretcher carriage provided with an offset lifting mechanism

摘要

The carriage (10) has a lower frame (12) provided with wheels (14), and an upper frame (22) comprising a bed, where the upper frame is connected to the lower frame through lifting arms (30, 32) to allow displacement of the upper frame relative to the lower frame. The arms pivot with respect to the lower frame around rotation axles (A, B) perpendicular to a longitudinal direction (L) of the bed and are actuated independently by actuators fixed to the lower frame. The arms have upper ends pivotingly mounted at feet and head sides of the upper frame and lower ends connected to the actuators.
