Abstract
A gurney includes a platform connected to a frame by two pairs of X-connected arms configured to reduce the amount of power required to raise the platform from its lowest position relative to the frame. A voltage doubling circuit is provided to approximately double the voltage applied to the motor to allow the platform to be raised and lowered relatively faster than normal. A rotating shaft in an internally threaded nut moves a cross beam to raise or lower the platform. The nut has interior bearings to reduce the friction between the shaft and the nut. A detent mechanism and a brake structure provide fail-safe locking of the platform at a plurality of heights.
