-23 Abstract LIFTING DEVICES AND METHODS A lift coupling system (22) includes a lifting base (24) attachable to an object (1). The lifting base includes a housing (50). Lift pins (70) move between a retracted state within the housing and an extended state wherein a portion of each of the lift pins extend outwardly from the housing. An actuator (36) moves the lift pins between the retracted and extended state. A lift collar (26) includes a lift collar body (58) configured to fit about the housing. The lift collar contacts and couples the lift pins to the lift collar when positioned about the housing and the lift pins are in the extended state and decouple therefrom when the lift pins are in the retracted state.
