Abstract
Abstract A hospital transfer trolley comprises a main frame from which two parallel end pieces extend at right angles so that a bed, trolley or the like can be received between the end pieces. A pair of horizontal lift members are carried by the end pieces and can be raised or lowered with respect to the end pieces. A couch including a mattress and a mattress support is movable between a horizontal patient-supporting position in which it is between the end pieces and an upright inoperative position on the main frame. The mattress support is engageable with the lift members when the couch is in its patient supporting position to enable the couch to be raised and lowered.
