ABSTRACT:
In one form, a belt lifter apparatus provides increased lifting force and belt lift height by a scissors mechanism having crossed lifting arms each having a translatable end and having a translatable pivot axis between the lifting arms. Preferably, other ends of the lifting arms are fixed to an upper belt lifting member and to a lower support base member at locations such that the pivot axis translates to a position located substantially at the center of the lifted belt when the belt is lifted to the highest lift height. Lightweight, aluminum tubular members are used for the lifting member and the base support and each includes a track for supporting the translatable ends of the lifting arms. The span width of the base member is adjusted by sliding telescoping, tubular legs within the base tubular element. Pivoted wing arms are supported by braces extending to the belt lifting member.
