A lift coupling system includes a lifting base attachable to an object. The lifting base includes a housing. Lift pins 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 moves the lift pins between the retracted and extended state. A lift collar includes a lift collar body 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. At least one lift tab may be arranged on the lift collar body configured to enable lifting of the lifting base and the object thereby when the lift collar is coupled to the lifting base.
