Abstract: A portable apparatus for lifting a television to be mounted on a wall has a base frame assembly with at least three support members, and a connecting member that is connected to a first end of a first support member, and a first end of a second support member and a first end of a third support member are pivotally connected to the base frame support member. A mast assembly having at least two segments is removably connected to the connecting member of the base frame assembly, and a trolley device is removably engaged with the mast assembly, where the trolley is capable of translating along the length of the mast assembly. A electronic device holding assembly that has at least two support arms, and a cross-member to which the support arms are connected, is removably engaged with the trolley, and a driving mechanism causes the trolley to translate along the length of the mast assembly. Thus, a flat screen television can be readily installed on a wall by operating the apparatus of the invention.
