1. An overhead lift apparatus comprising:
a mounting structure;
a rotatable assembly configured to attach a lift unit to the mounting structure, wherein the rotatable assembly is rotatable with respect to the mounting structure about an axis of rotation;
a rotatable electrical interface disposed in the rotatable assembly, wherein the rotatable electrical interface comprises a static portion and a rotatable portion attached to the rotatable assembly such that the rotatable portion rotates in conjunction with the rotatable assembly;
a first electrical connector extending from the static portion to a power source connector;
a second electrical connector extending from the rotatable portion;
a first lift unit attached to the rotatable assembly, the first lift unit comprising a lift unit power source conductively connected to the second electrical connector such that the first lift unit receives power from the power source via the rotatable electrical interface; and
a second lift unit attached to the rotatable assembly,
wherein the mounting structure comprises:
a first rail having a first carriage support channel formed in the first rail,
a second rail having a second carriage support channel formed in the second rail,
the second rail extending parallel to the first rail,
a first carriage slidably disposed in the first carriage support channel, and
a second carriage slidably disposed in the second carriage support channel; and
wherein power from the power source is provided through a second electrical conductor extending through the second rail, the apparatus further comprising a second carriage connector extending between the second carriage and the power source connector such that the power from the power source is provided from the second rail to the second lift unit via the second carriage and the rotatable assembly.
