摘要：
According to one embodiment, a cot (10) comprises a support frame (12) comprising a front end (17), and a back end (19)； a pair of front legs (20) pivotally coupled to the support frame (12), wherein each front leg (20) comprises at least one front wheel (26)； a pair of back legs (40) pivotally coupled to the support frame (12), wherein each back leg (40) comprises at least one back wheel (46)； a cot actuation system comprising a front actuator (16) that moves the front legs (20) and a back actuator (18) that moves the back legs (40), wherein the support frame (12) comprises a pair of parallel lateral side members (15) extending between the front end (17) and the back end (19)； the pair of parallel lateral side members (15) comprise tracks； each front leg (20) comprising a front carriage member (28) slidingly engaged with the tracks, and each back leg (40) comprising a back carriage member (48) slidingly engaged with the tracks； the front actuator (16) and the back actuator (18) raise or lower the support frame (12) together； the front actuator (16) being configured to raise or lower the front end (17) of the support frame (12) separately from the back actuator (18)； and the back actuator (18) being configured to raise or lower the back end (19) of the support frame (12) separately from the front actuator (16).
