Embodiments of a method of operation of a roll-in push cot for transport onto a first surface comprising initially loading the roll-in cot onto a first surface thereby releasing automatically at least one leading leg, continuing of loading the roll-in cot onto the first surface to move a front carriage member toward a front actuator, such that movement of the front carriage member triggers the front actuator that releases a middle release lever, thereby initiating the release of at least one trailing leg, supporting the weight of the cot at least partially in order to disengage a locking mechanism for the at least one trailing leg, and loading the cot in order to move a rear carriage member in conjunction with folding of the at least one trailing leg and thereby trigger a reset actuator and release a latch pin to engage the rear carriage member when the trailing and leading legs of the roll-in push cot are in a fully folded position on the first surface.
