1. A stowable modular lift conversion system (1500) configured for application to a vehicle, the system comprising:
a fixed frame (110) configured to mount to the vehicle, the fixed frame comprising:
an opposing pair of vertical frame members (111),
a first compression member (1510) captured between the opposing pair of vertical frame members (111),
a first tension member (1520) configured and adapted to generate inward pressure between opposing frame members against the first compression member (1510),
an upper pivot point (112) on each of the vertical frame members (111),
a lower pivot point (113) on each of the vertical frame members (111),
a hook (114) configured to inhibit translational motion of the fixed frame (110) in more than one direction, and
a multiaxial adjustable brace (1570) comprising a support surface (115) configured to support the fixed frame (110) against rotation; and
a movable frame (120) configured and adapted to lift a load and to move from a stowed configuration to an extended position, the movable frame comprising:
an opposing pair of upper pivot arms (121), each having a near end (121A) respectively connected to one of the upper pivot points (112), and a far end (121B) opposite the near end,
an opposing pair of lower pivot arms (122), each having a near end (122A) respectively connected to one of the lower pivot points (113), and a far end (122B) opposite the near end,
a second compression member (1510) captured and located between either the opposing pair of upper pivot arms (121), or the opposing pair of lower pivot arms (122),
a second tension member (1520) configured and adapted to generate inward pressure between opposing pivot arms (121, or 122) against the second compression member (1510),
an opposing pair of adaptive mounting plates (1530), each connected to the far end (121B) of one of the upper pivot arms (121) or to the far end (122B) of one of the lower pivot arms (122),
a modular implement base (140) connected to the opposing pair of adaptive mounting plates (1530), and
a safety bar (1540) movable from an open position to a closed position with respect to the modular implement base (140);
wherein the modular implement base (140) and the safety bar (1540) are each respectively adapted and configured such that a multiplicity of modular implements (151), (152), (153) can be detached from the modular implement base when the safety bar (1540) is in the open position, but not when the safety bar (1540) is in the closed position.
