A lifting platform with a scissor type jack. The jack includes a plurality of inter-connected struts pivotally connected to a base forming a double X strut arrangement. A power actuator is connected to at least one strut in each X to effect extension and retraction of the jack. A safety latch is provided to prevent accidental retraction of the jack from an extended position should the power actuator fail to hold the jack in the elevated position.
