An elevating cage apparatus includes a support structure and a carriage that is operable to move vertically with respect to the support structure. The carriage is configured to be alternatively raised and lowered via a first driver and a second driver. The first driver may comprise a powered (electric, hydraulic, or pneumatic) motor, and the second driver may comprise a manual actuation mechanism including a hand crank. Both input drivers may be operable to move the carriage through a dual input worm drive gear box.
