摘要：
Embodiments of a cot comprise a support frame, legs coupled to the support frame, at least one hydraulic actuator configured to raise or lower the legs, and a manual release system coupled to the at least one actuator and configured to lower the cot manually at a controlled descent rate. The manual release system comprises a manual actuation component, a manual release valve operable to be opened upon actuation by the manual actuation component, a fluid reservoir operable to receive hydraulic fluid from the at least one actuator upon opening of the manual valve； and a flow regulator configured to control the flow rate of the hydraulic fluid into the fluid reservoir, wherein the release of hydraulic fluid into the fluid reservoir at the controlled flow rate is configured to manually lower the cot at the controlled descent rate.
